highway completed in 1921 included concrete within the town of Manchester and a macadam highway from north of Frederick to Libertytown. By 1923, concrete roads were constructed from just east of Libertytown to north of Unionville and for south from New Windsor. MD 31 was completed between Libertytown and New Windsor in 1926. In 1933, MD 31 was truncated at Libertytown; the Frederick–Libertytown road became a westward extension of MD 26. The state highway was widened with a pair of macadam shoulders from Westminster to New Windsor between 1936 and 1939, resulting in a wide roadway between the two towns. A disjoint section of MD 31 was added in 1939 along Water Tank Road east of Manchester. The state highway, which extended from the eastern town limit of Manchester at Millers Station Road to Carrs Road, was removed from the state highway system in 1956. The first section of MD 31 to be reconstructed was east from Libertytown between 1949 and 1951. The state highway was also widened and resurfaced within Westminster starting in 1952. Construction began on reconstructing and widening MD 31 from Manchester to Westminster in 1957. This project involved several relocations of the highway by the time it was completed in 1960; sections of old road became segments of MD 852, including MD 852G between Westminster and Mexico. MD 31 was relocated from New Windsor to southwest of Westminster between 1963 and 1965; the old highway, Old New Windsor Pike, became another segment of MD 852. The final relocation of MD 31 around Westminster occurred in 1967 when the highway was relocated between Old New Windsor Pike and what is now MD 140. The old roadway that headed toward Western Maryland College and ran parallel to the new roadway for became MD 852K. Also in 1967, MD 31 was removed from Manchester Road, which became a northward extension of MD 27. MD 31's most recent relocation occurred in New Windsor in 2007. MD 31 originally entered town from the southwest along High Street, then turned east at Main Street. MD 31 was rerouted to follow High Street north to Green Valley Road at MD 75's present terminus, follow Green Valley Road south to Main Street at MD 75's old terminus, then turn east onto Main Street. The stretch of Main Street between its two intersections with MD 31 was designated MD 831. Junction list See also References
