Interstate 275

Interstate 275 (I-275) may refer to:

Tampa Bay

Tampa Bay is a large natural harbor and estuary connected to the Gulf of Mexico on the west central coast of Florida, comprising Hillsboro Bay, McKay Bay, Old Tampa Bay, Middle Tampa Bay, and Lower Tampa Bay. The surrounding area is home to about 4 million residents, making it a heavily used commercial and recreational waterway but putting much stress on the bay's ecosystem, which once teemed with enough wildlife to easily support an extensive indigenous culture. Much greater care has been taken in recent decades to mitigate the effects of human habitation on Tampa Bay, and water quality has slowly improved over time.

The term "Tampa Bay" is sometimes 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 the misconception that it is the name of a particular municipality when this is not the case.

Saint Petersburg

Saint Petersburg (Russian: Санкт-Петербу́рг, tr. Sankt-Peterburg; IPA: [ˈsankt pʲɪtʲɪrˈburk]) is the second largest city in Russia. It is politically incorporated as a federal subject (a federal city). It is located on the Neva River at the head of the Gulf of Finland on the Baltic Sea. In 1914 the name of the city was changed from Saint Petersburg to Petrograd (Russian: Петрогра́д; IPA: [pʲɪtrɐˈgrat]), in 1924 to Leningrad (Russian: Ленингра́д; IPA: [lʲɪnʲɪnˈgrat]), and in 1991, back to Saint Petersburg. In Russian literature, informal documents, and discourse, the word "Saint" is usually omitted, leaving "Petersburg". In casual conversation Russians may drop the "burg" as well, referring to it as "Peter": Russian: Питер (Piter).

Tsar Peter the Great founded Saint Petersburg on May 27 [O.S. 16] 1703. Between 1713–1728 and 1732–1918 Saint Petersburg functioned as the imperial capital of Russia. In 1918 the central government bodies moved from Saint Petersburg (then named Petrograd) to Moscow. It is Russia's second-largest city after Moscow, with 5 million inhabitants (2012), and the fourth most populated federal subject. Saint Petersburg is a major European cultural center, and also an important Russian port on the Baltic Sea.

Sunshine Skyway Bridge

The Bob Graham Sunshine Skyway Bridge, commonly known as the Sunshine Skyway Bridge, is a bridge spanning Tampa Bay, Florida, with a cable-stayed main span, and a total length of 21,877 feet (4.1 miles or approximately 6.67 km). It is part of I-275 (SR 93) and US 19 (SR 55), connecting St. Petersburg in Pinellas County and Terra Ceia in Manatee County, Florida, passing through Hillsborough County waters. Construction of the current bridge began in 1982, and the completed bridge was dedicated on February 7, 1987. The new bridge cost $244 million to build, and was opened to traffic on April 20, 1987. It replaced an older bridge constructed in 1954, which was partly destroyed in a collision in 1980.

It is constructed of steel and concrete. Steel cables clad in 84 9-inch (229 mm) steel tubes (42 per pylon) along the center line of the bridge support the main span. It was designed by the Figg & Muller Engineering Group (who also designed the popular Seven Mile Bridge), and built by the American Bridge Company.
