Minnesota State Highway 13 ( MN 13 ) is a 111.694-mile-long (179.754 km) highway in Minnesota that runs from its intersection with U.S. Highway 65 in Albert Lea to its northern terminus at its intersection with State Highway 149 at the West St. Paul / Saint Paul city boundary line.
31-451: State Highway 13 serves as a north–south route between Albert Lea, Waseca, Prior Lake, Savage, Burnsville, Eagan, Mendota Heights, West St. Paul, and the "West Side" neighborhood of Saint Paul. The southern terminus of the route is at the intersection of Main Street and Broadway Avenue ( U.S. 65 / Business Loop 35) in the city of Albert Lea. The northern terminus of Highway 13 is at
62-569: A circular green indication to show that turns in the direction of the arrow are prohibited, but other movements are allowed. In some jurisdictions, a red arrow prohibits a turn on red . In Europe, if different lanes have differing phases, red, yellow and green traffic lights corresponding to each lane have blacked-out areas in the middle in the shape of arrows indicating the direction(s) drivers in that lane may travel in. This makes it easier for drivers to be aware which traffic light they need to pay attention to. A green arrow may also be provided; when it
93-410: A right turn (across oncoming traffic) in one turn). It also allows for diagonal crossings ( pedestrian scramble ) and reduces crossing distances for pedestrians. Intersections generally must manage pedestrian as well as vehicle traffic. Pedestrian aids include crosswalks , pedestrian-directed traffic signals ("walk light") and over/ underpasses . Walk lights may be accompanied by audio signals to aid
124-565: A right turn on red, and sometimes left on red depending on the geometry of the intersection in question, possible in many cases, often without stopping. Cyclists ideally have a protected bike lane on the approach to the intersection, separated by a concrete median with splay kerbs if possible, and have a protected bike lane width of at least 2 metres if possible (one way). In the Netherlands , most one way cycle paths are at least 2.5 metres wide. Bicycle traffic can be accommodated with
155-415: A setback crossing of the pedestrians and cyclists , generally between 1.5–7 metres of setback, a forward stop bar, which allows cyclists to stop for a traffic light well ahead of motor traffic who must stop behind the crosswalk. Separate signal staging or at least an advance green for cyclists and pedestrians is used to give cyclists and pedestrians no conflicts or a head start over traffic. The design makes
186-603: A turn lane does not normally indicate a prohibition of turns in that direction. Instead, traffic control signs are used to prohibit specific turns. Turn lanes can increase the capacity of an intersection or improve safety. Turn lanes can have a dramatic effect on the safety of a junction. In rural areas, crash frequency can be reduced by up to 48% if left turn lanes are provided on both main-road approaches at stop-controlled intersections. At signalized intersections, crashes can be reduced by 33%. Results are slightly lower in urban areas. Turn lanes are marked with an arrow bending into
217-399: Is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange , which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design. This article primarily reflects practice in jurisdictions where vehicles are driven on
248-913: Is a four-way interchange on the German autobahn network. Autobahndreieck (literally "autobahn triangle"), short form dreieck , and abbreviated as AD, is a three-way interchange on the German autobahn network. At intersections , roads cross at-grade . They also can be further subdivided into those with and without signal controls. Signalized designs include advanced stop line , bowtie , box junction , continuous-flow intersection , continuous Green-T, double-wide, hook turn , jughandle , median u-turn, Michigan left , paired, quadrant , seagulls , slip lane , split, staggered , superstreet , Texas T , Texas U-turn and turnarounds . Non-signalized designs include unsignalized variations on continuous-flow 3 and 4-leg, median u-turn and superstreet, along with Maryland T/J, roundabout and traffic circle . In
279-577: Is a hybrid: traffic moving from CSAH 101 toward Highway 13 is grade separated, with through traffic connecting to Highway 13 north, and with exit and entrance ramps connecting to Highway 13 south; southbound traffic on Highway 13 uses a continuous green T-intersection , while through traffic connects to CSAH 101. Highway 13 is also built as a divided highway in Mendota Heights between I-494 (no interchange / junction) to State Highway 55. The section of Highway 13 north of State Highway 55 at Mendota
310-894: Is far less busy. Highway 13 is also known as Sibley Memorial Highway in Lilydale, Mendota, and Eagan. The Sibley House Historic Site museum in Mendota , overlooking Fort Snelling , is located immediately north of the junction of Highways 13 and 62 . The museum is on Highway 13. Highway 13 is also known as Langford Avenue in Spring Lake Township and Cedar Lake Township in Scott County. The route follows Main Street and 4th Avenue SW in New Prague . Highway 13 follows 4th Street in Montgomery . In
341-488: Is known from the crossing at Shibuya Station , Tokyo. In 2020, NHTSA reported that more than 50% of pedestrian deaths in the United States (3,262 total) were attributed to failure to yield the right of way-- which typically occurs at intersections. Poor visibility at junctions can lead to drivers colliding with cyclists and motorcyclists. Some junctions use advanced stop lines which allow cyclists to filter to

#1732794030575372-449: Is on, drivers heading in the direction of the arrow may proceed, but must yield to all other vehicles. This is similar to the right turn on red in the US. Disadvantages to turn lanes include increased pavement area, with associated increases in construction and maintenance costs, as well as increased amounts of stormwater runoff. They also increase the distance over which pedestrians crossing
403-515: Is where two or more roads meet. Roads began as a means of linking locations of interest: towns , forts and geographic features such as river fords . Where roads met outside of an existing settlement, these junctions often led to a new settlement. Scotch Corner is an example of such a location. In the United Kingdom and other countries, the practice of giving names to junctions emerged, to help travellers find their way. Junctions took
434-1195: The Michigan left / Superstreet (RCUT/MUT) and continuous flow intersection (CFI/DLT), to improve traffic flow, and also interchange types like Diverging diamond interchange (DDI/DCD) design as part of the Federal Highway Administration 's Every Day Counts initiative which started in 2012. Vulnerable road users include pedestrians, cyclists, motorcyclists, and individuals using motorized scooters and similar devices. Compared to people who are in motor vehicles (like cars and trucks), they are much more likely to suffer catastrophic or fatal injuries at an intersection. Intersections generally must manage pedestrian as well as vehicle traffic. Pedestrian aids include crosswalks , pedestrian-directed traffic signals ("walk light") and over / underpasses . Traffic signals can be time consuming to navigate, especially if programmed to prioritise vehicle flow over pedestrians, while over and underpasses which rely on stairs are inaccessible to those who can not climb them. Walk lights may be accompanied by audio signals to aid
465-638: The diverging diamond , Michigan urban diamond, three-level diamond , and tight diamond. Others include center-turn overpass, contraflow left, single loop, and single-point urban overpass. Non-signalized designs include the cloverleaf , contraflow left, dogbone (restricted dumbbell), double crossover merging , dumbbell (grade-separated bowtie), echelon, free-flow interchange , partial cloverleaf , raindrop , single and double roundabouts (grade-separated roundabout ), single-point urban , stack , and windmill . Autobahnkreuz (literally "autobahn cross"), short form kreuz , and abbreviated as AK,
496-643: The EU it is estimated that around 5,000 out of 26,100 people who are killed in car crashes are killed in a junction collision, in 2015, while it was around 8,000 in 2006. During the 2006–2015 decade, this means around 20% of road fatalities occur at junctions. By kind of users junctions fatalities are car users, 34%; pedestrians, 23%; motorcycle, 21%; pedal-cycle 12%; and other road users, the remaining. It has been considered that several causes might lead to fatalities; for instance: A number of features make this protected intersection much safer . A corner refuge island,
527-429: The case of railways or rail tracks the term at grade applies to a rail line that is not on an embankment nor in an open cut . As such, it crosses streets and roads without going under or over them. This requires level crossings . At-grade railways may run along the median of a highway . The opposite is grade-separated . There may be overpasses or underpasses . Junction (road) A junction
558-421: The city of Waseca , Highway 13 is also known as State Street . The 200MW (with possible expansion to 400MW) Bent Tree Wind Farm was scheduled to be built in 2009 along Highway 13 between Manchester and Hartland. The farm being developed by Wind Capital and Alliant Energy would be the biggest wind farm in the state of Minnesota. State Highway 13 was authorized in 1920 from Albert Lea to Jordan . In 1934,
589-512: The direction of the turn which is to be made from that lane. Multi-headed arrows indicate that vehicle drivers may travel in any one of the directions pointed to by an arrow. Traffic signals facing vehicles in turn lanes often have arrow-shaped indications. North America uses various indication patterns. Green arrows indicate protected turn phases, when vehicles may turn unhindered by oncoming traffic. Red arrows may be displayed to prohibit turns in that direction. Red arrows may be displayed along with
620-479: The front of a traffic queue which makes them more visible to drivers. A European study found that in Germany and Denmark, the most important crash scenario involving vulnerable road users was: These findings are supported by data elsewhere. According to the U.S. National Highway Traffic Safety Administration , roughly half of all U.S. car crashes occurred at intersections or were intersection related in 2019. In
651-573: The intersection of Annapolis Street and Smith Avenue ( Highway 149 ) at the West St. Paul / Saint Paul city boundary line. Highway 13 is built as a divided highway between Savage, Burnsville, and Eagan. This portion of the route is a busy metro area corridor paralleling the Minnesota River . At the junction with CSAH 101 in Savage, leading to US 169 , Highway 13 turns east. This junction

#1732794030575682-405: The intersection shown in the diagram, left turn lanes are present in the right-left street. Turn lanes allow vehicles, to cross oncoming traffic (i.e., a left turn in right-side driving countries, or a right turn in left-side driving countries), or to exit a road without crossing traffic (i.e., a right turn in right-side driving countries, or a left turn in left-side driving countries). Absence of
713-606: The low grade bike lanes in the roadway or higher grade and much safer protected bicycle paths that are physically separated from the roadway. In Manchester, UK, traffic engineers have designed a protected junction known as the Cycle-Optimised Signal (CYCLOPS) Junction. This design places a circulatory cycle track around the edge of the junction, with pedestrian crossing on the inside. This design allows for an all-red pedestrian / cyclist phase with reduced conflicts. Traffic signals are timed to allow cyclists to make
744-459: The name of a prominent nearby business or a point of interest. As of the road networks increased in density and traffic flows followed suit, managing the flow of traffic across the junction became of increasing importance, to minimize delays and improve safety. The first innovation was to add traffic control devices, such as stop signs and traffic lights that regulated traffic flow. Next came lane controls that limited what each lane of traffic
775-775: The right . If not otherwise specified, "right" and "left" can be reversed to reflect jurisdictions where vehicles are driven on the left . One way to classify intersections is by the number of road segments (arms) that are involved. Another way of classifying intersections is by traffic control technology: At intersections, turns are usually allowed, but are often regulated to avoid interference with other traffic. Certain turns may be not allowed or may be limited by regulatory signs or signals, particularly those that cross oncoming traffic. Alternative designs often attempt to reduce or eliminate such potential conflicts. At intersections with large proportions of turning traffic, turn lanes (also known as turn bays ) may be provided. For example, in
806-472: The route. The route was completely paved by 1940. In the late 1960s, U.S. Highway 16 was decommissioned in the Albert Lea area. Highway 13 was then extended east on Main Street in Albert Lea between its intersection with U.S. 69 to its intersection with U.S. 65 . Later, US 69 was truncated to the present terminus, and MN 13 was extended along US 69's route. In 1994, the nearby Mendota Bridge
837-532: The segment between New Prague and Jordan was redesignated Highway 21 , and Highway 13 moved to the east and extended north through Prior Lake, Savage, and Burnsville; then northeast to its northern terminus in West Saint Paul. From 1934 to 1935, Highway 13 also ran from Albert Lea south to the Iowa state line. In 1935, U.S. Highway 69 was extended north into Minnesota, assuming that 12 mile section of
868-438: The street are exposed to vehicle traffic. If a turn lane has a separate signal phase, it often increases the delay experienced by oncoming through traffic. Without a separate phase, left crossing traffic does not get the full safety benefit of the turn lane. Alternative intersection configurations, formerly called unconventional intersections, can manage turning traffic to increase safety and intersection throughput. These include
899-460: The visually impaired. Medians can offer pedestrian islands, allowing pedestrians to divide their crossings into a separate segment for each traffic direction, possibly with a separate signal for each. Some intersections display red lights in all directions for a period of time . Known as a pedestrian scramble , this type of vehicle all-way stop allows pedestrians to cross safely in any direction, including diagonally. All green for non motorists
930-982: Was allowed to do while crossing. Turns across oncoming traffic might be prohibited, or allowed only when oncoming and crossing traffic was stopped. This was followed by specialized junction designs that incorporated information about traffic volumes, speeds, driver intent and many other factors. The most basic distinction among junction types is whether or not the roads cross at the same or different elevations . More expensive, grade-separated interchanges generally offer higher throughput at higher cost. Single-grade intersections are lower cost and lower throughput. Each main type comes in many variants. At interchanges , roads pass above or below each other, using grade separation and slip roads . The terms motorway junction and highway interchange typically refer to this layout. They can be further subdivided into those with and without signal controls. Signalized ( traffic-light controlled) interchanges include such " diamond " designs as
961-623: Was rebuilt between Mendota Heights and Fort Snelling. Highway 13 was rerouted in Mendota Heights at this time so it could intersect with State Highway 55 and State Highway 110 (present day State Highway 62). The old alignment of Highway 13 in the southwest corner of Mendota Heights (Sibley Memorial Drive) is still under state maintenance and has the unmarked designation of Highway 913-A.
