MD 254 begins 0.03 miles (0.048 km) south of the intersection of Cobb Island Road and Neale Sound Drive on Cobb Island. Cobb Island Road continues south as a county-maintained two-lane divided avenue to Potomac River Drive on the Potomac River side of the island. North of Neale Sound Drive, MD 254 is a two-lane undivided road and leaves the island by crossing over Neale Sound on the Cobb Island Bridge. The state highway passes between marinas and curves northwest to parallel the coast. At Pine Grove Road, MD 254 veers north to its terminus at Rock Point Road. Rock Point Road heads southeast as a county highway toward Rock Point and northwest as MD 257 up Cobb Neck to U.S. Route 301 in Newburg.[1][2]
The original bridge from the mainland to Cobb Island, a "noisy one-way wooden bridge that was prone to summer traffic jams," was constructed in 1923 shortly after the establishment of the island as a summer resort by Robert Crain.[3] In 1932, the Maryland State Roads Commission rebuilt Cobb Island Road as a modern gravel road and replaced the "hazardous" 1923 bridge with a creosoted timber bridge.[4][5] This bridge was still one-lane, being 10 feet (3.0 m) wide, but had a passing area near the middle.[5] Cobb Island Road was originally designated MD 533.[6] MD 533 was widened to 24 feet (7.3 m) and resurfaced with bituminous stabilized gravel in 1951.[7] MD 533 was renumbered MD 254 in 1958.[8] MD 254 had originally been assigned to Davidsonville Road between Davidsonville and Edgewater in central Anne Arundel County; that highway was renumbered as an eastward extension of MD 214 (Central Avenue) by 1939.[6][5] A two-lane steel girder Cobb Island Bridge was built in 1963.[9] In 2015, plans were made to construct a new Cobb Island Bridge to replace the existing structure that was structurally deficient. The new Cobb Island Bridge, which includes wider travel lanes, a sidewalk, and lighting, cost $18 million to build and opened to traffic on April 28, 2020.[10]
The entire route is in Charles County.
