Interstate 275
Interstate 275 (I-275) in Florida serves the Tampa Bay metropolitan area, measuring 60.696 miles (97.681 km) in length. The southern terminus is I-75 near Palmetto, just five miles east of the Sunshine Skyway Bridge, a toll bridge crossing Tampa Bay. The highway passes through St. Petersburg, Florida before crossing Tampa Bay again on the Howard Frankland Bridge and entering Tampa, where it intersects with I-4 in Downtown. After the interchange, I-275 heads due north through the Tampa suburbs to its northern terminus at I-75 in Wesley Chapel.
Interstate 275 and its parent route, Interstate 75, are opposite the normal conventions of freeway routing. Normally, the parent route will go through a metropolitan area while a 3-digit numbered freeway (beginning with an even number) serves as the bypass route; however, in this case I-275 runs through Downtown Tampa and St. Petersburg, Florida while I-75 serves as the bypass route.
