These 26 highways are service roads constructed or old alignments maintained to provide access to private property or county highways whose access was compromised by the realignment of MD 2 and MD 4 in Calvert County.

The portions of MD 765 that form the old alignment of Solomons Island Road were part of the original state road constructed as in the early 1910s, which ran the length of Calvert County from Solomons to Owings and continued north toward Annapolis.

MD 2 continues south a short distance to its terminus at Lore Road in Solomons.

After meeting Southern Connector Boulevard, which heads west as unsigned MD 765Z, at a roundabout, the highway curves northeast to intersect MD 760 (Rousby Hall Road) and pass through the village center of Lusby.

Following this, the road passes Middleham Chapel and the entrance to Calvert Cliffs State Park.

MD 765Q continues north a short distance on the west side of the divided highway, passing Sollers Wharf Road before turning east to its northern terminus at another intersection with MD 2-4 south of Johns Creek, a tributary of St. Leonard Creek.

MD 765P reaches its northern terminus when Nursery Road turns east to a barricade at a secondary entrance to Calvert Cliffs Nuclear Power Plant.

Parkers Creek Road heads south to a full service intersection with MD 2-4 and north toward Scientists Cliffs.

[8] The highway was graded and surfaced as an improved dirt road from Owings south to Hunting Creek in 1910 and 1911 and from there to Prince Frederick between 1911 and 1913.

[10] This highway was improved to a gravel road for its whole length and several dangerous curves were modified by 1919.

[16] The MD 2 reconstruction continued south a few miles to the northern end of Lusby in 1942, a stretch widened to 22 feet (6.7 m) and resurfaced with bituminous stabilized gravel.

[21] By 1946, the highway had been relocated to its modern alignment and paved north of Armory Road.

[22] The bypassed portion of Armory Road was marked as MD 750 by 1950 but may have been removed from the state highway system by 1952.

[20] This improvement occurred contemporaneously with or shortly before the construction of the Prince Frederick bypass; MD 2 moved to the new 24-foot (7.3 m) wide bituminous stabilized gravel highway in the autumn of 1951.
