State Road 804's western terminus is in unincorporated Boynton Beach at the intersection of US 441–SR 7, just north of the eastern boundary of the Loxahatchee National Wildlife Refuge and the historic northern boundary of The Everglades.

East of Knuth Road, Boynton Beach Boulevard enters incorporated Boynton Beach and becomes more commercial, with the Boynton Beach Mall a few blocks to the north, and SR 804 intersecting with Congress Avenue, which like Military Trail is a state turned county road.

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. At the intersection with US 1, SR 804 leaves Boynton Beach Boulevard proper for US 1 (Federal Highway, and the hidden SR 5), where it continues south for two blocks. SR 804 then turns left (east) and follows Ocean Avenue in downtown Boynton Beach, along portions of the Ocean Avenue Historic District, with a speed limit of The road also has access to the revitalized Boynton Harbor Marina to the north before crossing a drawbridge over the Intracoastal Waterway to the eastern terminus at SR A1A (Ocean Boulevard), which is just outside the Boynton Beach city limits in Ocean Ridge, just south of Boynton Beach's Oceanfront Park and Boynton Beach's government offices.

The original designation of Boynton Beach Boulevard was State Road 195. The 1945 State Road renumbering changed that designation to the current State Road 804. The road originally began as Boynton West Road at State Road 7, about 1/2 mile south of the current western terminus, connecting the farms in that area to the town of Boynton Beach to the east. Boynton West Road headed east to Military Trail at the eastern end of a sugarcane field, where the road would follow Military Trail for 1/2 mile northbound, with the field to the west. The road would continue east, and then south to Boynton West Shellrock Road (now Old Boynton Road), where the road would head east to its original eastern terminus at Dixie Highway (now Federal Highway, US 1, and SR 5) and NW 2nd Avenue.
