After the interchange with I-95, West Atlantic Avenue continues eastward, entering downtown Delray Beach, where the highway begins intersecting with numbered local streets now as a four-lane boulevard. The surroundings become a mix of residences and commercial industries until NW 6th Avenue, when it becomes purely commercial. SR 806 passes to the south of the Delray Beach Tennis Center and its lanes begin to merge as the highway approaches the intersection with Swinton Avenue. At Swinton Avenue, West Atlantic Avenue changes names to East Atlantic Avenue, and SR 806 continues eastward along East Atlantic. Also at the intersection with Swinton Avenue, SR 806 narrows to a two lane undivided avenue. At this point, the state has relinquished control of East Atlantic to the city of Delray Beach, and the segment is not part of SR 806. At the intersection with North Railroad Avenue, the road crosses the Florida East Coast Railroad and continues through downtown Delray Beach. At the intersection with NE 5th Avenue, East Atlantic Avenue intersects with US 1 (unsigned SR 5) southbound, where the state regains control of the road and SR 806 resumes. A block later, the route intersects the US 1 northbound lanes (NE 6th Avenue). SR 806 widens to a four lane undivided avenue for the remainder of East Atlantic. After US 1, the highway continues eastward, crossing Veterans Park and then crossing over Intracoastal Waterway on a large drawbridge. After the drawbridge, East Atlantic Avenue continues eastward, passing several high-rise residences until terminating at an intersection with SR A1A in Delray Beach, along the Atlantic Ocean.
