U.S. 29 travels 25 miles through the state of Maryland from Washington, D.C. north to Mt. Hebron. The highway exists in two forms. The southern two thirds of the highway varies between a congested surface arterial to expressway with interchanges at Maryland 216 and Maryland 650. The northern third from Maryland 32 to Maryland 99 is a full freeway with numbered interchanges.
U.S. 29 began as a freeway between Maryland 99 (Original U.S. 40) and U.S. 40 (Baltimore National Pike). Upgrades to the route occurred between the 1970s and 1990s, converting the surface boulevard portion of U.S. 29 between U.S. 40 and Maryland 32 (Patuxent Freeway) into a full freeway. The upgrade of U.S. 29 into a freeway was completed as part of the planning for the city of Columbia in central Howard County.
