MD 90 continues east through Ocean Pines, where the highway has a diamond interchange with MD 589 (Racetrack Road) and passes over Ocean Parkway within that community. The median barrier ends and the state highway becomes an undivided highway again immediately before crossing the St. Martin River on a long bridge. A median returns right after the bridge ends at Isle of Wight, where MD 90 has an at-grade signalized intersection with St. Martins Neck Road and the entrance to Isle of Wight Nature Park. MD 90 becomes undivided again for the Assawoman Bay Bridge over the Assawoman Bay. After that bridge, the state highway expands to four lanes with a Jersey barrier for a short distance before its terminal intersection with MD 528 (Coastal Highway) at 62nd Street in the Midtown section of Ocean City.
