It is known locally and signed as Boynton Beach Boulevard for nearly all of its route, with the exception of when the road becomes concurrent with U.S. Route 1 (US 1 southward for two blocks, then continues along Ocean Avenue in downtown Boynton Beach to its eastern terminus at SR A1A.

West of US 441, Boynton Beach Boulevard continues westbound as 100th Street South for 0.5 miles (0.80 km) without a state road designation through several farms before terminating at a dead end.

The speed limit here, and on almost all of Boynton Beach Boulevard outside of the incorporated city, is 45 miles per hour (72 km/h).

East of the turnpike, Boynton Beach Boulevard enters into some residential areas, intersecting Jog Road, followed by Military Trail (formerly SR 809 and now CR 809), where soon afterwards, it has access to the Quail Ridge Country Club to the south.

It crosses the Florida East Coast Railway tracks that carry the Brightline service, also passing the site of a proposed Tri-Rail station south of the boulevard.
