At its northern end, MD 210 starts from the end of South Capitol Street in Washington, D.C., connecting the U.S. Capitol with Indian Head, Maryland. This state route is accessed from the Capital Beltway by way of Exit 2A (northbound only), Exit 3 (northbound and southbound) and from ramps to and from the southern terminus of Interstate 295. Maryland Route 210 is part of the National Highway System as an arterial route from the Washington, D.C. city line to Maryland Route 228. The Metrobus system provides local bus transportation for various stops along the highway.

Maryland Route 210 begins in Indian Head, Maryland in Charles County along the four-lane, divided, arterial Indian Head Highway, beginning at an intersection with Potomac Avenue within the town. It is located close to the Naval Surface Warfare Center. The section of the highway in Charles County features many direct intersections, with homes and businesses directly fronting the road. The route then heads northeast out of the town into woodland, passing through Potomac Heights and Bryans Road as it exits Charles County.

Maryland (ⁱ/ˈmɛrɨlənd/) is a U.S. state located in the Mid Atlantic region of the United States, bordering Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware to its east. Maryland was the seventh state to ratify the United States Constitution, and three nicknames for it (the Old Line State, the Free State, and the Chesapeake Bay State) are occasionally used. Maryland is the 9th smallest state by area, but the 19th most populous and the 5th most densely populated of the 50 United States. The state's most populated city is Baltimore. Its capital is Annapolis. It was named after Queen Henrietta Maria.

Maryland has an area of 12,406.68 square miles (32,133.2 km²) and is comparable in overall area with the European country of Belgium (11,787 square miles (30,530 km²)).

Wonder Woman is a fictional character, a DC Comics superheroine created by William Moulton Marston. She first appeared in All Star Comics #8 (December 1941). The Wonder Woman title has been published by DC Comics almost continuously except for a brief hiatus in 1986.

Wonder Woman is a warrior Princess of the Amazons (based on the Amazons of Greek mythology) and was created by Marston, an American, as a "distinctly feminist role model whose mission was to bring the Amazon ideals of love, peace, and sexual equality to a world torn by the hatred of men." Known in her homeland as Diana of Themyscira, her powers include superhuman strength, flight (even though the original Wonder Woman did not have this ability), super-speed, super-stamina, and super-agility. She is highly proficient in hand-to-hand combat and in the art of tactical warfare. She also possesses animal-like cunning skills and a natural rapport with animals, which has been presented as an actual ability to communicate with the animal kingdom. She uses her Lasso of Truth, which forces those bound by it to tell the truth, a pair of indestructible bracelets, a tiara which serves as a projectile, and, in some stories, an invisible airplane.
