Interstate 175

The Interstate begins at I-275 with Tropicana Field on the northeast side of the interchange, going east into downtown St. Petersburg, passing through eastbound exits with 9th Street South/8th Street South and 6th Street South before the Interstate ends at 5th Avenue South next to an at-grade intersection with 4th Street South. Westbound, the Interstate begins with a split from southbound 4th Street South just north of the 4th Street South/5th Avenue South intersection and has no exits until the interchange with I-275. Along with its sister highway, I-375, I-175 lacks exit numbers. ==History==

The freeway was originally to have been a part of the former Pinellas Belt Expressway, which would have continued from its western terminus at I-275. The Pinellas Belt Expressway was budgeted in 1974 but was canceled in the late 1970s due to local opposition. I-175 was built between 1977 and 1980 and opened on April 23, 1980, at a cost of $5.5 million (equivalent to $ in ). When I-75 was relocated in the late 1970s–early 1980s, of additional Interstate became available; thus, the St. Petersburg feeder sections of I-175 and neighboring I-375 were upgraded to Interstate status. ==Exit list==
