'''Interstate&nbsp;175''' ('''I-175''') in St. Petersburg, Florida, also known as '''South Bay Drive''', is a {{Convert|1.3|mi|km|-long|adj=mid}} spur route from I-275 into downtown St. Petersburg. It is also designated as the unsigned highway '''State Road&nbsp;594''' ('''SR&nbsp;594''').<ref name="InterchangeReport" /> There is a sibling segment of freeway nearby designated as I-375.

==Route description== 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.<ref name="SLD"/>

==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.<ref>{{cite web |access-date=August 4, 2021 |title=Pinellas County |url=https://www.aaroads.com/florida/pinellas/ |website=AARoads}}{{sps|date=August 2021}}</ref> I-175 was built between 1977 and 1980 and opened on April 23, 1980, at a cost of $5.5&nbsp;million (equivalent to ${{formatprice|{{Inflation|US-GDP|5500000|1980}}}} in {{Inflation-year|US-GDP}}<!--Government estimate cost = using US-GDP for inflation estimate-->{{Inflation/fn|index=US-GDP}}).<ref name="seroads">{{cite web|url=http://www.southeastroads.com/i-175_fl.html|title=I-175 at South-East highways|access-date=October 5, 2014}}</ref>

When I-75 was relocated in the late 1970s–early 1980s, {{convert|5|mi|km|spell=in}} of additional Interstate became available; thus, the St. Petersburg feeder sections of I-175 and neighboring I-375 were upgraded to Interstate status.{{citation needed|date=March 2014}}
