82-901: Interstate 376 ( I-376 ) is a major auxiliary route of the Interstate Highway System in the US state of Pennsylvania , located within the Allegheny Plateau . It runs from I-80 near Sharon south and east to a junction with the Pennsylvania Turnpike ( I-76 , its parent) in Monroeville , after having crossed the Pennsylvania Turnpike at an interchange in Big Beaver . The route serves Pittsburgh and its surrounding areas and
164-516: A cloverleaf interchange . I-76 then passes through Wadsworth , Norton , and Barberton and then enters Akron ; this section of road was built as US 224. Soon after entering Akron, I-76 turns north onto the short Kenmore Expressway. US 224 leaves I-76 there and continues east with I-277 toward I-77. Shortly after heading north from the I-277 interchange, I-76 meets I-77 and again turns east, joining southbound I-77 south of downtown Akron on
246-671: A trumpet interchange southwest of the city in Taylor Township . At this point, I-376 becomes a toll road officially named the James E. Ross Highway. I-376 continues southward, still paralleled by PA 18 and the Beaver River to the east. Shortly after entering Beaver County near Koppel , the route connects to its parent route I-76 ( Pennsylvania Turnpike ) for the first time at an interchange which also provides access to PA 351 . Around this area, I-376 crosses into

Interstate 376 Business ( I-376 Bus ) or Business Loop 376 ( BL 376 ), known locally as the Airport Parkway, is a six-mile (9.7 km) Interstate Highway business loop in Moon Township and Findlay Township in Pennsylvania . Its western terminus
492-578: A generally easterly direction through Churchill , Wilkins Township , Penn Hills , and finally Monroeville , where I-376 ends at an interchange with the Pennsylvania Turnpike and US 22 Bus . US 22 continues east from this interchange on the William Penn Highway toward Murrysville . The James E. Ross Highway portion of I-376 between US 422 and PA 51 uses all-electronic tolling , with tolls payable by toll by plate (which uses automatic license plate recognition to take
574-699: A high-speed surface road to provide access to the airport. In 1955, the Baltimore and Ohio Station was demolished to make way for construction of the new freeway. In late 1956, it opened from the Boulevard of the Allies (then US 22/US 30) near the Birmingham Bridge east to Bates Street, with the eastbound lanes opening September 10 and westbound opening September 29. The other downtown sections opened in segments from January 17, 1958, to 1959,
656-529: A marker, which was a new addition to the 2009 edition of the Manual on Uniform Traffic Control Devices . Despite PennDOT giving motorists over four years of advance notice on the I-376 extension, some local drivers were confused after the transition was complete, thinking that the I-376 extension was going to be an all-new highway instead of a renaming of PA 60. As part of the ongoing upgrades to I-376 to bring
738-554: A new alignment (already built as US 224 ) from Akron west to I-71 east of Lodi ; the rest of proposed I-80 west to near Norwalk (which would have crossed I-71 near Medina ) was removed from the Interstate Highway System. I-80 was moved to the turnpike between Streetsboro and southwest of Cleveland c. 1971 ; the old route became I-480 . On April 16, 1963, due in part to the extension of I-79 south from Greater Pittsburgh , Pennsylvania proposed
820-431: A partial renumbering. A new number, tentatively designated I-76, would run from Downtown Pittsburgh east on what was then I-70 (I-70S bypassed Pittsburgh to the south on what is now I-70) to the Pennsylvania Turnpike at Monroeville , and then east along the remainder of I-80S to I-295. I-80S would remain on the section of turnpikes from west of Youngstown to Monroeville. This was approved February 26, 1964, and included
902-597: A partially-unsigned concurrency (indicated only on reassurance markers ), continuing east-southeastward bearing the Penn-Lincoln Parkway name, and soon reach an interchange with I-79 . From that point eastward, along what was known for many years as I-279, I-376 runs east-southeast through Rosslyn Farms and Carnegie before turning northeast and passing through Green Tree . Entering the city of Pittsburgh , I-376 winds its way northeast to its second interchange with PA 51 at Saw Mill Run Boulevard, which

The tolled section of I-376 has two mainline toll plazas: the West Mainline Toll Plaza near milepost 18 and the East Mainline Toll Plaza near milepost 30. As of 2024, the West Mainline Toll Plaza costs $ 5.50 using toll by plate and $ 2.90 using E-ZPass for passenger vehicles while the East Mainline Toll Plaza costs $ 3.50 using toll by plate and $ 1.50 using E-ZPass for passenger vehicles. There are also ramp tolls at

Some examples of beltways include: Interstate 76 in Pennsylvania Interstate ;76 ( I-76 ) is an east–west Interstate Highway in the Eastern United States . The highway runs approximately 435.66 miles (701.13 km) from an interchange with I-71 west of Akron, Ohio , east to I-295 in Bellmawr, New Jersey . This route
1148-619: A southerly direction on the Beaver Valley Expressway, a four-lane freeway with a wide grass median. Paralleling PA 18 , I-376 has its first interchange with that state highway in West Middlesex . I-376 soon meets US 422 and forms an overlap with that highway along the west side of New Castle . After an interchange with US 224 in Union Township , I-376 eastbound splits from US 422 at
1230-458: A state. There are three states that have no auxiliary Interstate Highways: Alaska, Arizona, and New Mexico. North Dakota has an auxiliary route, but it is unsigned , and Wyoming's does not meet Interstate Highway standards. Auxiliary Interstates are divided into three types: spur , loop , and bypass routes. The first digit of the three digits usually signifies whether a route is a bypass, spur, or beltway. The last two digits are derived from
1312-674: Is tolled and is maintained by the Pennsylvania Turnpike Commission (PTC), while the remainder of the highway is maintained by the Pennsylvania Department of Transportation (PennDOT). Near the airport, I-376 also has a business loop . I-376 begins at a cloverleaf interchange with I-80 and PA 760 located four miles (6.4 km) east of Ohio within the Glaciated Allegheny Plateau . From there, it travels in
1394-582: Is also part of a spread-out series of ramps linking Banksville Road ( US 19 ) and US 19 Truck . This junction, located just before the freeway passes under Mount Washington in the Fort Pitt Tunnel , features the infamous wrong-way concurrency of the northbound and southbound directions of US 19 Truck. After passing through the Fort Pitt Tunnel, I-376 emerges onto the four-lane double-deck Fort Pitt Bridge , crossing over
1476-612: Is at I-376 and Flaugherty Run Road (exits 50 and 51) north of PIT . Its eastern terminus is at I-376's exit 57, southeast of PIT. Before November 6, 2009, and after the Southern Expressway was completed in 1992, this road was known as PA 60 Bus. Prior to that, it had the regular PA 60 designation; this was also originally the last leg of the Parkway West which ended at the intersection with then-Beers School Road (now University Boulevard) and began as
1558-638: Is not contiguous with I-76 in Colorado and Nebraska . Just west of Youngstown , I-76 joins the Ohio Turnpike and heads around the south side of Youngstown. In Pennsylvania , I-76 runs across most of the state on the Pennsylvania Turnpike , passing near Pittsburgh and Harrisburg before leaving the turnpike at Valley Forge . At Valley Forge, I-76 becomes the Schuylkill Expressway , eventually enters Philadelphia , and then crosses
1640-528: Is signed east–west despite running north–south for nearly three-quarters of its length; however, it does run east–west through the majority of Allegheny County. This is because, until 2009, the route's western terminus was at I-279 in Downtown Pittsburgh ; it was extended west and north to I-80 to give the corridor a single route designation. Despite the route's direction, it serves as a major artery through Pittsburgh's West End , with I-79 being
1722-730: Is the main access road to Pittsburgh International Airport (PIT). Portions of the route are known as the Beaver Valley Expressway , Southern Expressway , and Airport Parkway . Within Allegheny County , the route runs along the majority of the Penn-Lincoln Parkway , known locally as Parkway West and Parkway East . It is currently the ninth-longest auxiliary Interstate route in the system and second only to I-476 within Pennsylvania. I-376

Once across the river, the route touches down in Downtown Pittsburgh at Point State Park . An interchange at the Point connects I-376 to I-279 (Parkway North), which leads to the Fort Duquesne Bridge , as well as Liberty Avenue. I-376 continues east from
1886-478: The Ohio River . It then has its second interchange with PA 18 near Kobuta and continues south from there. I-376 passes to the west of Aliquippa before leaving Beaver County and entering Allegheny County . Approaching PIT , I-376 bends south-southwest and becomes the Southern Expressway, while the Beaver Valley Expressway diverges to the southeast along I-376 Business (I-376 Bus). I-376 circles around
1968-540: The PA ;80 designation until that route was decommissioned due to Pennsylvania needing the designation for I-80 to the north. In 1956, PA 60 was commissioned to have the Airport Parkway and the former alignment of US 22 and US 30 to Pittsburgh's West End. From 1959 to 1964, I-70 occupied the highway east of PA 50 in Carnegie . When I-70 moved to its current alignment (replacing I-70S) in 1964,
2050-582: The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users in 2005, Congress had designated an expansion of I-376 past I-79 and along present day US 22/US 30 and PA 60 through Pittsburgh International Airport and north to I-80 near Sharon . This was done because the airport was one of the few major airports in the US without direct access to an Interstate Highway. This routing required some major infrastructure work on US 22 west of Downtown Pittsburgh (particularly at
2132-684: The Unglaciated Allegheny Plateau , where it remains for the remainder of its length. I-376 then passes to the east of West Mayfield and becomes a non-tolled highway again at its first interchange with PA 51 in Chippewa Township , just west of Beaver Falls . The freeway then weaves through mountainous terrain, interchanging with PA 68 in Vanport just before crossing the Vanport Bridge over
2214-605: The Walt Whitman Bridge into New Jersey . After only about three miles (4.8 km) in New Jersey, I-76 reaches its eastern terminus, though the freeway continues south as Route 42 . I-76 begins at exit 209 of I-71 in Westfield Township , approximately six miles (9.7 km) east of Lodi, Ohio ; U.S. Route 224 (US 224) continues west from the end of I-76. The interchange
2296-727: The Walt Whitman Bridge over the Delaware River into New Jersey is with I-95 . Some of the ramps involve traffic signals , as the ramps to I-95 were retrofitted into an existing interchange when I-95 was built, and the tollbooth for the bridge lies west of the crossing of the two roads. Just after crossing the Delaware River on the Walt Whitman Bridge, I-76 turns south and becomes the North–South Freeway , which carries I-676 north to Downtown Camden ;

Expressway an eastern extension of I-76, they feel that making the change without a compelling reason would only add to motorists' confusion in southern New Jersey. The majority of I-76 along the Pennsylvania Turnpike includes the first long-distance rural freeway in the U.S.; the Ohio Turnpike and Schuylkill Expressway are also pre-Interstate freeways. By 1955,
2460-514: The Beaver Valley Expressway in 1971, PA 60 was extended to its future northern terminus in Chippewa. Finally, on October 2, 1972, after I-76 west of Monroeville moved to the Pennsylvania Turnpike and replaced I-80S, the western part of the highway took the I-279 designation while the section from Pittsburgh east to Monroeville would become the first section with the I-376 designation. When I-376

The Beaver Valley Expressway was selected as a test area so that the PTC could work out any bugs with mailing non-E-ZPass users bills with their unpaid tolls. The first section of what would eventually become I-376 opened June 5, 1953, from PA 885 (Bates Street) near the Hot Metal Bridge east through the Squirrel Hill Tunnel to US 22 Bus (then US 22) at Churchill . Construction commenced on this stretch on July 25, 1946, near Wilkinsburg . The next section to open, running from PA 60 ( Steubenville Pike , then US 22 / US 30 ) near PIT east to Saw Mill Run Boulevard ( PA 51 and US 19 ), opened October 15, 1953. At Steubenville Pike, it connected to PA 60—the Airport Parkway —which had been built c. 1950 as

Much of the road is up to freeway standards, but several signaled at-grade intersections remain, making this multilane divided road a true expressway (unlike many of Pennsylvania's freeways , which are often misleadingly named using the suffix expressway, since they are often called such in the northeast). I-376 Bus is one of only two business Interstate routes found in

This is in stark contrast to the mainline Turnpike, which charges less than $ 0.12 per mile ($ 0.07/km) for E-ZPass users and more than $ 0.17 per mile ($ 0.11/km) for cash users. This is due to the bonds on newer sections of the Turnpike system (such as

A partial interchange provides access to SR 59 ( the Innerbelt ), and then I-76 crosses through the Central Interchange, where I-77 goes south (on the South Expressway) and SR 8 begins to the north (on the North Expressway); I-76 switches from the West Expressway to the East Expressway. Leaving the Akron area, I-76 again heads through rural areas, crossing Portage County and entering Mahoning County . West of Youngstown ,

I-76 joins the Ohio Turnpike heading southeast toward Pittsburgh while I-80 exits the Turnpike and continues east toward Youngstown. The Ohio Turnpike carries I-76 until the Pennsylvania border, where I-76 joins the Pennsylvania Turnpike . From the Ohio border, the Pennsylvania Turnpike carries I-76 into and across most of Pennsylvania , bypassing Youngstown, Ohio , to

In the early to mid-1980s, the entire section from downtown to Monroeville was refurbished. The next leg of the route opened to PA 108 in 1991 and to PA 51 in Chippewa on November 30, 1992, as the 16.5-mile (26.6 km) $ 260-million (equivalent to $ 507 million in 2023) "missing link" between two sections of PA 60, when that route's designation

It marked the third partial interchange on the legacy PA 60/Parkway West to be upgraded to
4182-441: The main Interstate Highway. For instance, I-115 contains an odd number in the first digit (1), which indicates that this freeway is a spur. The last two digits signify the highway's origin. In this case, the "15" in I-115 shows that it is a supplement to I-15 . Exceptions to the standard numbering guidelines exist for a number of reasons. In some cases, original routes were changed, extended, or abandoned, leaving discrepancies in

Some routes connect to the parent route at one end but to another route at the other end; some states treat these as spurs while others treat them as bypasses. Like the primary Interstate Highways , auxiliary highways meet Interstate Highway standards (with rare exceptions ). The shorter auxiliary routes branch from primary routes; their numbers are based on

With some exceptions, spur routes are numbered with an odd hundreds digit (such as I-395 ), while bypasses and beltways are numbered with an even hundreds digit (such as I-695 ). Because longer Interstates may have many such supplemental routes, the numbers can repeat from state to state along their route, but they will not repeat within

4510-481: The renumbering of all I-X80 spurs to I-X76. On June 29, 1970, a renumbering was approved in the Pittsburgh area, with the main effect being rerouting I-79 to bypass Pittsburgh to the west on the former I-279 . I-279 was moved to the former I-79 north of downtown, and the former I-79 from downtown southwest to new I-79 became a western extension of I-76. (It was then that I-876 was designated for former I-479 .) A realignment and extension of I-76 into Ohio, taking over
4592-431: The rest of I-80S to I-71 east of Lodi, was approved January 11, 1972. The former I-76 from Monroeville west into Downtown Pittsburgh became I-376 , and I-279 was extended southwest from downtown along former I-76 to I-79. (I-876 was renumbered to I-579 then.) Signs in Ohio were changed September 1, 1972; the old I-80S signs remained for about a year. On August 29, 1972, a swap of I-76 and I-676 in Philadelphia and Camden

4756-451: The route received the I-76 designation into Pittsburgh. West of Pittsburgh, from 1963 to 1970, I-79 occupied the route. In West Middlesex, the route would receive the PA 18 designation while the former alignment would receive a business route designation as PA 18 Business, since it served as a bypass of West Middlesex. In 1970, I-79 swapped positions with I-279 , necessitating that I-76 be extended to I-79. With commencement on

A spur route 's number usually has an odd number for its first digit. It is usually one of the following: Examples include: Sometimes, a three-digit Interstate Highway branches off from another three-digit Interstate Highway. These spurs do not connect directly with their parent highways, but are associated with them via
5494-472: The three-digit highways they do intersect with. Examples include: A bypass route may traverse around a city, or may run through it with the mainline bypassing. In a typical 3-digit Interstate Highway, bypasses usually have both its two termini junctioned with another Interstate highway. Bypass routes are preceded by an even number in the first digit. Examples include: In the case of an auxiliary Interstate highway which has both ends at Interstates but not
5576-399: The tolled section of I-376 in 2006 at both the two mainline toll plazas as well as the exits that collect tolls. A bridge crossing I-376 from Oakland to Greenfield, the Greenfield Bridge , gained some national notoriety on an episode of Last Week Tonight with John Oliver concerning infrastructure . The state could not immediately afford to replace the crumbling bridge, so instead a cover
5658-417: The total cost of the parkway at this time came to $ 112.11 million (equivalent to $ 896 million in 2023). The $ 6.31-million (equivalent to $ 50.4 million in 2023) Fort Pitt Bridge opened June 19, 1959, followed by the $ 16-million (equivalent to $ 126 million in 2023) Fort Pitt Tunnel on September 1, 1960, using the West End Bypass (PA 51) and Carson Street ( PA 837 ) as detours until
5740-509: The turnpike was still not assigned a number from near Elyria (where I-80N and I-90 would split from it) to west of Youngstown. The route from west of Youngstown to Philadelphia was assigned I-80S, and extended east to I-295 in New Jersey when auxiliary Interstates were assigned in 1959. (The planned I-80N in Pennsylvania became I-78.) Initial spurs of I-80S were I-180 (now I-176 ), I-280 (now I-276 ), I-480 (now I-476 ), and I-680 (now I-676 , though it swapped with I-76 in 1972). I-80
5822-407: The unsigned Route 76C connector runs east to US 130 and Route 168 . The exit numbers in New Jersey are backward, running from east to west. Though signed eastbound toward Atlantic City , the route ends near Gloucester City in western Camden County at an interchange with I-295 . From the exit for I-676 to the end, I-76 originally had local–express lanes in both directions;
5904-650: The western terminus of I-376. Work began on the Beaver County sections of I-376 (in between Chippewa Township and the Airport Parkway) in 1971 and would finish by 1976. The following year, the northern section finished construction, which would leave a gap between New Castle and Chippewa Township for the next 15 years. Until the middle section was completed, in order to continue on the highway, travelers had to use US 422 , PA 168 , PA 18, PA 251 , and PA 51 before returning to
5986-731: Was approved. I-76 had been routed along the Vine Street Expressway and Ben Franklin Bridge (now I-676) through Center City, while I-676 used the Schuylkill Expressway and Walt Whitman Bridge to bypass downtown to the south. The switch was made because of delays in building the Vine Street Expressway, better interchange geometry at the splits, and that the Ben Franklin Bridge ends in city streets, rather than in expressway grade. The renumbering of
6068-469: Was built under the bridge to protect the vehicles on I-376. The Greenfield Bridge was finally demolished in December 2015, and a replacement was built over the following two years, officially opening on October 14, 2017. From PA 60 to I-376's eastern terminus, I-376 has had the US 22 and US 30 designations for its entire history (US 30 exiting at Wilkinsburg). Until 1961, it also carried
6150-570: Was complete. On January 21, 2010, the remainder of the route except for the Beaver Valley Expressway started receiving the I-376 signs. The stretch of PA 60 from I-80 in Shenango Township of Mercer County north past PA 18 (where the freeway terminates and the highway reverts to being a two-lane arterial) to the former northern terminus of PA 60 in Sharon became PA 760. On August 1, 2010, signage along PA Turnpike 60
6232-537: Was completed with a toll highway. When the Beaver Valley Expressway started opening in 1991, it would receive the "PA Toll 60" designation, because it was operated by the PTC . With the opening of the Southern Expressway in 1992, PA 60 moved to that highway, while the Airport Parkway received the PA ;60 Bus designation. PA 60 was eventually extended to Sharon in 1997, ending at US 62 Bus . As part of
6314-613: Was drawn on a map from 1947, which did not include several changes that had been approved, specifically the Keystone Shortway across Pennsylvania. (The route in that corridor ran further north, along US 6 , and was numbered I-84 .) Thus, the final numbering, approved in 1958, assigned I-80 to the Norwalk–Youngstown route to reach the Keystone Shortway. The former alignment through Cleveland became I-80N;
6396-399: Was extended onto the Parkway West in 2009, I-279 was truncated to its current southern terminus at the former western terminus of I-376. PA 18 Business was decommissioned in 1978 when PA 18 returned to its former alignment (where it has remained to this day) and PA 60 was extended all the way to Hermitage. On November 30, 1992, the 16.2-mile (26.1 km) gap in Beaver County
6478-420: Was officially changed to I-376, and, unlike other tolled highways with an Interstate designation, it is not grandfathered from Interstate standards . Having been built in the early 1990s, this section was already up to Interstate standards. This section of I-376 is signed as "Toll I-376", with a black-on-yellow "Toll" sign above the I-376 trailblazer. This makes I-376 one of the first tolled Interstates with such
6560-452: Was on the highway. The aforementioned "END 60" sign was removed when the first leg of the middle section opened in 1991, and a "No re-entry this exit" sign has sat on the site since due to exit 12A being an indirect connection to US 422 westbound without a direct reentry ramp. The Southern Expressway, a southern bypass of PIT, opened on September 9, 1992, and is the newest portion of I-376. The PTC retrofitted E-ZPass lanes on
6642-403: Was previously a double trumpet but was reconstructed in 2010. Officially, I-76 begins at the beginning of the ramp from I-71 north; it merges with US 224 at mile 0.61. After passing through rural Medina County , I-76 enters Summit County and soon crosses State Route 21 (SR 21, old US 21 ), once the main north–south route through the area until I-77 replaced it, at
6724-519: Was realigned in Ohio by 1962, largely taking over former I-80N, which ran through Cleveland, joining the turnpike southwest of Cleveland. However, while I-80N was planned to split from I-80 near Kent and run northwest to Cleveland along SR 14 , the new alignment of I-80 used the turnpike between the crossing west of Youngstown and the crossing with SR 14 at Streetsboro . The former I-80 from near Youngstown west to Akron became part of I-80S, as did
