State Road 687 comprises an urban route wholly within the city of St. Petersburg. The 9.45-mile alignment originates at the east end of Interstate 175 and SR 594 (5th Avenue S) just outside Downtown St. Petersburg. The state road forms a one-way street couplet through Downtown along 4th Street S (southbound) and 3rd Street N and 5th Avenue N (northbound) between SR 594 and SR 595.
North from 5th Avenue S, SR 687 doubles as U.S. 92 along the 4th Street N business corridor to the Gateway area in north St. Petersburg. There U.S 92 branches east along Gandy Boulevard along the unsigned SR 600 to the Gandy Bridge and South Tampa while SR 687 travels solo along a more wide open 4th Street N to Old Tampa Bay at the Howard Frankland Bridge approach. SR 687 ends at a wye interchange with I-275 north near Cedar Point.
State Road 687 originally extended south all the way to Pinellas Point and Pinellas Point Drive through south St. Petersburg. This segment generally remained along 4th Street S, with the exception of a westward shift on 6th Street S through Lakewood Terrace to circumvent Big Bayou. This north-south extension tied into an east-west branch of SR 687 in the Pinellas Point neighborhood. This segment stemmed west from 4th Street S via 62nd Avenue S, Royhanna Drive and Pinellas Point Drive to then 34th Street S (U.S. 19).
