Tampa Bay is a large natural harbor and shallow estuary connected to the Gulf of Mexico on the west-central coast of Florida , comprising Hillsborough Bay, McKay Bay , Old Tampa Bay, Middle Tampa Bay, and Lower Tampa Bay. The largest freshwater inflow into the bay is the Hillsborough River , which flows into Hillsborough Bay in downtown Tampa . Many other smaller rivers and streams also flow into Tampa Bay, resulting in a large watershed area .
61-555: Gandy Bridge is the southernmost bridge spanning Old Tampa Bay from St. Petersburg, Florida to Tampa, Florida . The original 1924 span was dismantled in 1975. The second bridge, constructed in 1956 was used for vehicular traffic until 1997, when it was converted to recreational use by non-motorized traffic. It became known as the Friendship Trail Bridge and was demolished in 2016, after closing in 2008 due to hazardous conditions and several failed efforts to preserve
122-531: A certificate of necessity from the War Industries Board headed by Bernard Baruch . The project was not approved and financing was canceled. Gandy bought out Fuller's interests and continued alone. In 1922, Gandy hired promoter Eugene M. Elliott to attract new investment. Gandy sold enough stock to finance the bridge, which cost $ 1.932 million. Construction began in September 1922 and the bridge
183-518: A leak of 65 million gallons of acidic water from a Cargill phosphate plant on the bay's southern shore severely impacted wetlands in the vicinity of the spill. And in April 2021, a breach of a wastewater reservoir at the long-closed Piney Point phosphate plant sent over 200 millions gallons of nutrient-rich mine tailings streaming into lower Tampa Bay. The resulting growth of red tide algae led to an ecocide and killed over 1000 tons of fish in
244-567: A traffic bottleneck." In 1956 a second slightly higher, fixed span was added to the Gandy Bridge to serve westbound traffic. The first span would then serve eastbound traffic until 1975. The second bridge remained in use until February 1997. Years before, the Florida Department of Transportation (FDOT) deemed the bridge structurally deficient to vehicular traffic unless costly repairs were made. FDOT initially planned to demolish
305-416: Is a Florida State Park located on the north and south sides of the mouth of Tampa Bay . When the original cantilevered Sunshine Skyway Bridge , carrying I-275 ( US 19 ), partially collapsed in 1980, due to the collision of a freighter on one of its pilings, it was replaced by the current bridges. The approaches to the old bridge, however, were left in place and converted into the longest fishing pier in
366-459: Is extremely vulnerable to sea level rise caused by climate change. The sea level has risen 8 inches (200 mm) since 1946. Tampa Bay is also one of the areas in the US most at risk when hurricanes arrive because of its location, growing population, and the geography of the bay. The Tampa Bay Regional Resiliency Coalition coordinates the region's response to climate change. Communities throughout
427-787: Is silty and sandy, with an average water depth of only about 12 feet (3.7 m). The relatively shallow water and tidal mud flats allow for large sea grass beds, and along with the surrounding mangrove -dominated wetlands, the bay provides habitat for a wide variety of wildlife. More than 200 species of fish are found in the waters of the bay, along with bottlenose dolphins and manatees , plus many types of marine invertebrates including oysters , scallops , clams , shrimp and crab . More than two dozen species of birds, including brown pelicans , several types of heron and egret , Roseate spoonbills , cormorants , and laughing gulls make their year-round home along its shores and small islands, with several other migratory species joining them in
488-660: The American Recovery and Reinvestment Act . A peer review done by E.C. Driver and Associates disagreed on the repair estimate claiming it would take $ 48 million to repair the bridge. Also in July 2009, the animal rights group, People for the Ethical Treatment of Animals (PETA) offered to contribute funds to help save the Friendship Trail. However, the group asked for fishing to be banned throughout
549-403: The 1950s. However, industrial and agricultural runoff along with runoff from developed areas pose a continuing threat to marine ecosystems in the bay, particularly by clouding the water with sediments and algae blooms, and seagrass coverage declined slightly in the late 2010s. Wastewater pollution from old phosphate plants near the shoreline has been a particular problem. For example, in 2004,
610-485: The 1956 bridge reopened to pedestrian and bicycle traffic on December 11, 1999, as the Friendship Trail Bridge. On November 6, 2008, the Friendship Trail was shut down "indefinitely" (though the ends remained open) after a state inspection determined that there were significant structural problems with the bridge's superstructure. The bridge had been decaying for years, eventually forcing the closure of
671-601: The Bay, including St. Petersburg and Tampa are adapting infrastructure and buildings to face changes in sea level. Humans have lived in Florida for millennia, at least 14,000 years. Due to worldwide glaciation, sea levels were much lower at the time, and Florida's peninsula extended almost 60 miles west of today's coastline. Paleo-Indian sites have been found near rivers and lakes in northern Florida, leading to speculation that these first Floridians also lived on Tampa Bay when it

The Corps of Engineers currently maintains more than 80 miles of deep-water channels in Tampa Bay up to a depth of 47 feet. These must be continuously re-dredged and deepened due to the sandy nature of the bay bottom. While dredging has enabled seaborne commerce to become an important part of

The United States acquired Florida from Spain in 1821. The name Spirito Santo seems to have disappeared from maps of the region in favor of "Tampa Bay" (sometimes divided into Tampa and Hillsboro Bays) soon after the US established Fort Brooke at

Dredged material has also been used to create several spoil islands on the eastern side of Hillsboro Bay. These islands have become important nesting sites for many seabirds, including threatened species such as oystercatchers , and have been designated as "sanctuary islands" that are off-limits to boaters. In

Spanish maps dated from 1584 identifies Tampa Bay as Baya de Spirito Santo ("Bay of the Holy Spirit "). A map dated 1695 identifies the area as Bahia Tampa . Later maps dated 1794 and 1800 show the bay divided with three different names, Tampa Bay west of
1037-426: The aging third (1975) span. The new span is slated to be constructed along the north side of the fourth (1996) span, perhaps right over where the second (1956) span once stood. While the agency has identified that work will include widening the fourth span, it is currently unclear as to whether the span will only have widened shoulders, or if an additional travel lane will be added. It is also unclear as to how many lanes
1098-575: The area for over a century. The United States took possession of Florida in 1821 and established Fort Brooke at the mouth of the Hillsborough River in 1824. The communities surrounding Tampa Bay grew tremendously during the 20th century. Today, the area is home to about 4 million residents, making Tampa Bay a heavily used commercial and recreational waterway and subjecting it to increasing amounts of pollutants from industry, agriculture, sewage, and surface runoff . The bay's water quality
1159-534: The bay and along the nearby gulf coast and may lead to further damage to seagrass beds. The effects of Hurricane Milton in October 2024 caused polluted waste from the fertilizer industry including products from Mosaic , which were retained after the production of phosphate, to enter into Tampa Bay. Both Hurricane Milton and Hurricane Helene caused disruption in the production of phosphate fertilizers from Tampa Bay. Tampa Bay, like other parts of Florida ,
1220-479: The bay are distributed among over a hundred small tributaries, rather than a single river. The Hillsborough River is the largest such freshwater source, with the Alafia , Manatee , and Little Manatee rivers the next largest sources. Because of these many flows into the bay, its large watershed covers portions of five Florida counties and approximately 2,200 square miles (5,700 km ). The bottom of Tampa Bay
1281-507: The bay was connected to the Gulf of Mexico. This culture, which relied almost exclusively on the bay for food and other resources, was in turn replaced by the similar Safety Harbor culture by approximately 800 AD. The pre-contact Indigenous nation most associated with the Tampa Bay are the historic Tocobaga nation, who are known to be among the ancestors of the contemporary Seminole and Miccosukee Tribes of Florida. The Safety Harbor culture

#17327721925221342-488: The bay. Not finding gold or silver in the vicinity and unable to convert the native inhabitants to Christianity, the Spanish did not remain in the Tampa Bay area for long. However, diseases they introduced decimated the native population over the ensuing decades, leading to the near-total collapse of every established culture across peninsular Florida. Between this depopulation and the indifference of its colonial owners,
1403-566: The bridge On June 27, 2012, the Hillsborough County Commission voted to allow the group more time to evaluate their options for the bridge. It would also allow the commission to decide on a plan to possibly present a referendum to voters in November to hike the property tax to fund park improvements. Despite the various community efforts to save the bridge, none were able to fully materialize. Gradual demolition work

Beginning in the early 1980s after federal and state legislation to improve water quality, authorities installed improved water treatment plants and tightened regulation of industrial discharge , leading to slow but steady improvement in water quality and general ecological health. By 2010, measures of sea grass coverage, water clarity, and biodiversity had improved to levels last seen in
1525-478: The city of Tampa's downtown wharves on Hillsboro Bay. Most ships would anchor well out from shore and transfer cargo and passengers to and from the city in smaller boats. Henry B. Plant 's railroad line reached the area in 1884 and ran across the Interbay Peninsula to Old Tampa Bay, where he built the town and shipping facility of Port Tampa at its terminus. In 1898, Plant used his connections in
1586-399: The clearing of mangroves for shoreline development were important factors. Most damaging was the discharge of waste water and other pollutants into the bay, which drastically degraded water quality. The bay's health reached a low point in the 1970s. The water was so murky that sunlight could not reach the shallow bottom, reducing sea grass coverage by more than 80% compared to earlier in
1647-408: The early 20th century, traveling overland between the growing communities around Tampa Bay was an arduous process. The trip between Tampa and St. Petersburg was almost 50 miles (80 km) around the north end of Old Tampa Bay and took up to 12 hours by train and over a full day over uncertain roads by car. The trip between St. Petersburg and Bradenton was even longer – over 70 miles (110 km) all

In March 2011, citizens came together to save the bridge again, proposing a public/private partnership to fund repairs. In April 2011, Hillsborough County Commission voted to delay the demolition in order to give a group of citizens 30 days to come up with a viable plan to repair and re-open

Tampa Bay formed approximately 6,000 years ago as a brackish drowned river valley type estuary with a wide mouth connecting it to the Gulf of Mexico . Prior to that time, it was a large fresh water lake, possibly fed by the Floridan Aquifer through natural springs . Though the exact process of

That project was cancelled due to the new developments. December 17 brought further gloom for the trail when preliminary estimates to retrofit the bridge added up to about $ 30 million. Furthermore, the projected costs would only provide a temporary solution to

The term "Tampa Bay" is often used as shorthand to refer to all or parts of the Tampa Bay area , which comprises many towns and cities in several counties surrounding the large body of water. Local marketing and branding efforts (including several professional sports teams, tourist boards, and chambers of commerce) commonly use the moniker "Tampa Bay", furthering
2318-517: The opening ceremony. During George Gandy's speech, he stated; "The bridge is built!" The bridge was dismantled in 1975 immediately after completion of a third span. Efforts to preserve the bridge for recreational purposes were not supported by the Pinellas County Commission, which felt the idea was too expensive, too dangerous, and unnecessary. By 1947, state Sen. Raymond Sheldon described the bridge as "outmoded, too narrow and

With the state and the nation in recession, county governments saw no way to meet the staggering costs, leaving the trail likely closed for good. December 20, 2008 a report done by Kisinger Campo & Associates and SDR Engineering Consultants showed that the bridge could potentially collapse due to the amount of decay on the structure. Immediately after

The difficulty of traveling between Tampa and St. Petersburg in the early 20th century inspired the world's first scheduled air service, the St. Petersburg-Tampa Airboat Line , which operated during the tourist season of 1914. While the construction of bridges made air travel across Tampa Bay unnecessary, several airports have been built along
2928-483: The three bridges are obvious to observers. The westbound span is nine feet higher than the older eastbound span, and has a more gradual hump than its counterpart. The design and architecture of the westbound bridge is similar to the Clearwater Pass Bridge replacement, which was completed in 1994. In June 2021, FDOT announced that it is conducting a study to construct a fifth span to eventually replace
2989-459: The waters were rich enough that they were one of the few Native American cultures that did not have to farm. The Tocobaga was likely the dominant chiefdom in the area when Spanish explorers arrived in the early 1500s, but there were likely smaller chiefdoms on the eastern side of the bay which were not well documented. The indigenous population had been decimated by disease and warfare by the late 1600s, and there were no permanent human settlements in
3050-553: The way around Tampa Bay, a trip that still took about two hours into the 1950s. In 1924, the Gandy Bridge over Old Tampa Bay reduced the driving distance between Tampa and St. Petersburg to 19 miles (31 km). Ten years later, the Davis Causeway (later renamed the Courtney Campbell Causeway ) was built between Clearwater and Tampa. More bridges criss-crossed Tampa Bay over the ensuing decades, making travel between
3111-550: The western bay shore opposite Tampa. By 2010, the Tampa Bay Area was home to over 4 million residents. As Tampa began to grow in the mid-1800s, roads across central Florida were still just rough trails and rail lines did not yet extend down the Florida peninsula, so the most convenient means of traveling to and from the area was by sea. By the late 19th century, however, the shallow nature of Tampa Bay made it impossible for large modern vessels with deeper drafts to reach

The steel and concrete bridge spanned a distance of two and a half miles, making it the longest automobile toll bridge in the world at that time. Its double steel bascule drawbridge had a clearance span of 75 feet (23 m) and operated electrically. The original toll to cross the bridge was $ .75 for an automobile and driver and $ .10 for additional passengers. The bridge stopped collecting tolls on April 27, 1944, after it

The Tocobaga , who built their principal town near today's Safety Harbor in the northwest corner of Old Tampa Bay, are the most documented group from that era because they had the most interactions with Spanish explorers . However, there were many other coastal villages organized into various small chiefdoms all around

On December 23, 1945, a federal jury awarded The Gandy Company $ 2,383,642 in compensation for the property, plus $ 100,000 in interest. The bridge reduced the distance between Tampa and St. Petersburg from 43 to 19 miles (31 km). Its location enabled travel by auto along the route of the world's first scheduled airline flight , which operated between Tampa and Saint Petersburg for six months in 1914. The Gandy Bridge opened on November 20, 1924 Sixteen visiting state governors and several foreign dignitaries attended

Greater care has been taken in recent decades to mitigate the effects of human habitation on Tampa Bay, most notably upgraded sewage treatment facilities and several sea grass restoration projects, resulting in improved water quality over time. However, occasional red tide and other algae blooms have caused concern about

Evidence of human habitation from this early period has been found at the Harney Flats site, which is approximately 10 miles east of the current location of Tampa's downtown waterfront. The earliest evidence of human habitation directly on the shores of Tampa Bay comes from the Manasota culture , a variant of the Weeden Island culture , who lived in the area beginning around 5,000–6,000 years ago, after sea levels had risen to near modern levels and
