A six-mile-long continuation of Gulf Boulevard along Sand Key (to the bridge over Clearwater Pass) is designated 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).
As of September 2013, FDOT and Pinellas County have discussed relinquishing SR 699 to county control with the rest of Gulf Boulevard.[2]

Bridges
John's Pass Bridge
The original/second John's Pass bascule bridge in 2007, before it was replaced by the current bridge.
The John's Pass Bridge is a twin-span double-leaf bascule bridge that crosses the John's Pass, connecting Madeira Beach and Treasure Island, Florida. The bascule bridge carries Gulf of Mexico Boulevard, part of SR 699. The southbound span of the Johns Pass Bridge was built in 2008, and the northbound span was built in 2010.[4][5]
The first bridge was a two-lane bascule bridge built in 1927. But, the growth in the immediate Johns Pass area and strong currents could make the bridge collapse. Construction began on the second bridge in the late 1960s and was completed in 1971.
The second bridge was a twin-span bascule bridge built in 1971. But, the swift current prevalent in John's Pass. The frequent yet justified bridge openings have had motorists waiting lengthy periods to get across. One business just immediately south of John's Pass advertised drinks for 50 cents if the bridge was going up. Construction began on the current bridge in 2006.
The current bridge is a bigger twin-span bascule bridge built in 2008 (southbound) and 2010 (northbound). The southbound span of the second bridge has been demolished in 2006, and construction began on the current southbound. When the current southbound span was completed in 2008, the northbound span of the second bridge has been demolished, and construction began on the current northbound. The current northbound span was completed in 2010.[6]
