MD 713 has five
unsigned auxiliary routes and one former auxiliary route. MD 713A through 713E are associated with the construction of MD 100 through Hanover in the 1990s. MD 713F was assigned as part of the project to connect Arundel Mills Boulevard with MD 295. • MD 713A was the designation for a state-maintained section of Clark Road west from MD 713 just south of Arundel Mills Boulevard. MD 713A was transferred to private ownership and removed from the state highway system in 2008. • MD 713B is the designation for the L-shaped state-maintained portion of Ridge Chapel Road. The highway heads north from MD 713, then turns east at the southern end of MD 713C (Teague Road) and reaches its eastern terminus at an entrance to Harmans Park, which contains
Joe Cannon Stadium, a local baseball venue named for
Joseph Jerome Cannon, a major league baseball player who grew up in Anne Arundel County. The north–south part of MD 713B is the old alignment of MD 713. • MD 713C is the designation for Teague Road, a section of the old alignment of MD 713 between MD 713B and a cul-de-sac adjacent to MD 100. MD 713C also provides access to Joe Cannon Stadium. • MD 713D is the designation for Ridge Road, a section of the old alignment of MD 713 between a dead end adjacent to MD 100 and MD 176. • MD 713E is the designation for the state-maintained section of Ridge Road on both sides of the road's intersection with New Ridge Road north of MD 176. • MD 713F is the designation for the section of Arundel Mills Boulevard through its
diverging diamond interchange with MD 295. The interchange was constructed as a
dumbbell interchange in 2001 and designated MD 713F in 2002. The interchange was transformed into Maryland's first diverging diamond interchange in June 2012 to better serve the surge in traffic expected from the opening of the Maryland Live! casino at Arundel Mills that same month. ==See also==
