List of former Maryland state highways (700–999)
The Maryland highway system has several hundred former state highways. These highways were constructed, maintained, or funded by the Maryland State Roads Commission or Maryland State Highway Administration and assigned a unique or temporally unique number. Some time after the highway was assigned, the highway was transferred to county or municipal maintenance and the number designation was removed from the particular stretch of road. In some cases, a highway was renumbered in whole or in part. This list contains all or most of the state-numbered highways between 700 and 999 that have  existed since highways were first numbered in 1927 but are no longer part of the state highway system or are state highways of a different number. Most former state highways have not had their numbers reused. However, many state highway numbers were used for a former highway and are currently in use. Some numbers have been used three times. The former highways below whose numbers are used presently, those that were taken over in whole or in part by another highway, or have enough information to warrant a separate article contain links to those separate highway articles. Highway numbers that  have two or more former uses are differentiated below by year ranges. This list does not include former Interstate or U.S. Highways, which are linked from their respective lists. MD 711. Maryland Route 711 was the designation for Dogwood Road, which ran from MD 545 east to MD 280 (now MD 213) near Elkton in northeastern Cecil County. The highway and a bridge across Dogwood Run were constructed as a wartime access project in 1942 and 1943 to provide better access to the Triumph Explosives plant along MD 545. MD 711 was transferred from state to county maintenance in a  road transfer agreement on May 8, 1958. MD 714. Maryland Route 714 was the designation for Rivers Edge Road, which ran from Rivers Edge West north to MD 291 west of Millington in eastern Kent County. The highway was created to re-establish access to the portion of Rivers Edge Road cut off by the construction of what is now US 301 near Millington between 1954 and 1957. MD 714 was transferred from state to county maintenance through a December 1, 1987, road transfer agreement. MD 752. Maryland Route 752 was the designation for Hallowing Lane, a spur south from  MD 231 just east of the Benedict Bridge near Barstow. The route was transferred to the Maryland Department of Natural Resources in an agreement dated June 29, 2017. MD 787. Maryland Route 787 was the designation for Flower Avenue, which ran from MD 195 north to MD 320 within Takoma Park in southeastern Montgomery County. Flower Avenue from Carroll Avenue to Piney Branch Road was paved as a concrete road by 1923. The pavement was extended from Piney Branch Road north to Franklin Avenue in Silver Spring between 1931 and 1933. Flower Avenue between MD 195 and MD 516 (Franklin  Avenue), was designated MD 194 by 1939. MD 194 was widened to and resurfaced with asphalt concrete from MD 195 to MD 320 in 1947. The highway from MD 320 to MD 516 was resurfaced in 1954. In 1955, MD 194 was involved in a route number swap involving three routes in different parts of the state. At the time, MD 71 was assigned to the highway connecting Frederick with Taneytown, which connected with Pennsylvania Route 194 at the Maryland–Pennsylvania state line. MD 71 was reassigned to the new Blue Star Memorial Highway on the Eastern Shore; this designation  would be replaced with US 301 in 1959. The Frederick–Taneytown highway was assigned MD 194 to match its Pennsylvania counterpart. Flower Avenue's designation was changed to MD 787. The portion of MD 787 from MD 320 to Franklin Avenue was transferred from state to county maintenance in 1999. This mileage swap, which included the transfer of MD 516 as well, was conducted to bring MD 119 (Great Seneca Highway) into the state highway system. The following year, a short segment of MD 787 south of MD 195 was removed from the state highway system. This segment, which extended  south to Chaney Drive, had already been maintained by the city of Takoma Park. Chaney Drive had been where Flower Avenue intersected the Montgomery–Prince George's county line before the county line was moved in 1997 to place Takoma Park entirely within Montgomery County. The remaining state-maintained portion of Flower Avenue functioned as more of a city street than a state highway, and the city of Takoma Park desired to reconstruct it as a "green street" with improved stormwater management and complete sidewalks on both sides of the street. In November 2010, after a series of discussions on  several state highways in the city, the Takoma Park city council proposed the city receive ownership of Flower Avenue from the state in exchange for a one-time payment of $696,000, which was the amount the Maryland State Highway Administration had planned to spend to repave MD 787. The city would use the state payment toward reconstructing Flower Avenue after ownership was transferred to the city. Flower Avenue from MD 195 to MD 320 was officially transferred from the state to the city of Takoma Park through a road transfer agreement on August 1, 2012. MD 801. Maryland Route  801 was the designation for Irelands Corner Road, which ran between intersections with MD 313 on either side of MD 290 south of Galena in northeastern Kent County. The highway was originally paved in two segments. Kent County constructed the first segment, north of MD 290, with state aid as part of the concrete road from Galena south to Lambson Station between 1915 and 1919. The southern segment was built as part of the Galena–Massey highway; the concrete road was constructed in 1921 and 1922. MD 801 was assigned to Irelands Corner Road after MD 313 was reconstructed and  relocated south from Galena in 1956 and 1957; the segment of MD 290 between MD 801 and MD 313 was constructed at the same time. MD 801 was transferred from state to county maintenance through a December 1, 1987, road transfer agreement. MD 803. Maryland Route 803 was the designation for two segments of Edgar Price Road with a total length of near Warwick in southern Cecil County. The western segment paralleled the northbound side of US 301 from MD 299 to where it curved southeast from the U.S. Highway, where the county-maintained portion of the road began. The  eastern segment of MD 803 began where Edgar Price Road curved northeast. The highway met the southern end of MD 822 before reaching its eastern terminus at the Delaware state line. The portion of the county highway west from the state line was reconstructed as the eastern section of MD 803 was reconstructed as a state highway in 1955. The western section was constructed as a service road to reconnect MD 299 with Edgar Price Road, which was cut off by the construction of MD 71 (now US 301) between 1954 and 1956. MD 803 was transferred to county maintenance  through a December 27, 1979, road transfer agreement. MD 809. Maryland Route 809 was the designation for a pair of sections of old alignment of MD 273 at Calvert and near Fair Hill in northern Cecil County. MD 811.

MD 811 was transferred from state to town maintenance in a road transfer agreement on January 5, 1979. MD 812. Maryland Route 812 was the designation for a pair of sections of old alignment of MD 280 (now MD 213) near Singerly in northeastern Cecil County. Both routes were created after MD 280 was relocated north of Singerly between 1956 and 1958.

MD 823 was transferred from state to county maintenance in a road transfer agreement on December 27, 1979. MD 835. Maryland Route 835 was the designation for a section of old alignment of US 1 (now MD 273) near Rising Sun in northwestern Cecil County. The highway formed a loop on the south side of US 1 west from the western town limit of Rising Sun at Stone Run toward  Harrisville. MD 835 was assigned to the loop of old alignment after US 1 was reconstructed and straightened west of Rising Sun in 1952 and 1953. The highway was transferred from state to county maintenance through a May 8, 1958, road transfer agreement. The loop that comprised MD 835 ceased to exist as a road by 1971. MD 857. Maryland Route 857 was the designation for Medders Road and the portion of Rosedale Cannery Road east of Medders Road, which had a length of between intersections with MD 566 in Still Pond in northern Kent County.

Maryland Route 880 was the designation for Michaels Mill Road, a route that ran from MD 85 east to MD 80 in Buckeystown, Frederick County. MD 880 was designated in 1975 on the former  alignment of MD 80 after that route was shifted south to a new alignment. On November 18, 2008, MD 880 was removed from the state highway system and transferred to Frederick County. MD 895. Maryland Route 895 was the designation for Lockwood Drive, a route that ran from US 29 to MD 650.

Both highways were originally part of MD 283, which was paved as a concrete road on the north side of Earleville in 1928. MD 912 was assigned to the L-shaped part of Peddlers Lane after MD 282 was reconstructed and relocated from Cecilton to north of Earleville in 1966 and 1967; MD 282 had previously had a  right-angle turn at Peddlers Lane. MD 912A was bypassed when MD 282 was relocated north of Earleville in 1967 and 1968; MD 282 had previously turned at a four-way intersection with Grove Neck Road and Sandy Bottom Road.
