Locally known as Gulf Boulevard and Blind Pass Road, State Road 699 is a 15-mile-long road running the length of the Pinellas County barrier islands in the Gulf of Mexico and serving the popular beaches near St. Petersburg, Clearwater, and Largo. The southern terminus of SR 699 is at the extreme western end of Pinellas Bayway (SR 682) in St. Pete Beach; the northern terminus is the extreme western end of SR 688 in Indian Rocks Beach. State Road 699 is the closest Gulf Coast analog to SR A1A on the Atlantic coast of Florida: indeed, the southernmost two miles (3 km) of SR 699 (between Corey Causeway (SR 693) and the Pinellas Bayway) are part of a loop that Florida Department of Transportation once designated (and the Pinellas County Commission still calls) A19A.

A six-mile-long continuation of Gulf Boulevard along Sand Key (to the bridge over Clearwater Pass) is designated Pinellas County Road 183; a similar, shorter extension south of SR 682, Pass-a-Grille Way to Pass-a-Grille Park, is not a designated State or County Road. In addition to SR 688, SR 693, and the Pinellas Bayway, access to SR 699 from the mainland is made via the Stuart Welch Causeway (SR 666) and the Treasure Island Causeway (CR 150).
