Site Navigation Delaware District of Columbia Maryland New Jersey Pennsylvania Virginia West Virginia     U.S. Highway 29 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 started out as a freeway between Maryland 99 (Original U.S. 40) and U.S. 40 (Baltimore National Pike). However between the 1970s and 1990s, the surface boulevard portion of U.S. 29 between U.S. 40 and Maryland 32 (Patuxent Freeway) was converted 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. U.S. 29 Highway North U.S. 29 (Columbia Pike) northbound at the Exit 17 folded-diamond interchange with Seneca and Shaker Drives. Shaker Drive snakes northwest from Eden Brook Drive and Maryland 32 to the intersection with Seneca Drive at Exit 17. Seneca Drive serves residential areas of Atholton and Hickory Ridge within the immediate vicinity of Columbia Pike. Photo taken 09/25/04. Broken Land Parkway, like Shaker Drive, also travels northwest from the Maryland 32 freeway to meet U.S. 29 (Columbia Pike). The divided highway serves the Owen Brown community east of U.S. 29 and the Columbia Town Center to the west. Use Exit 18 for the Merriweather Post Pavilion, Oakland Hills, Hickory Ridge, and Howard Community College. A directional cloverleaf interchange joins the two highways in one half mile. Photo taken 09/25/04. U.S. 29 (Columbia Pike) continues north from Broken Land Parkway to junction Maryland 175 (Exits 20A/B) to the northeast of Columbia. Maryland 175 (Little Patuxent Parkway) constitutes an east-west surface arterial between Columbia and Jessup. Photo taken 09/25/04. Maryland 175 travels 17.01 miles east from U.S. 29 (Exit 20) to Maryland 3 (Crain Highway) at Millersville. The state highway serves the nearby communities of Oakland Mills and Long Branch on the eastward drive to Interstate 95 at Waterloo. Little Patuxent Parkway continues west from Columbia Pike to Wilde Lake. Photo taken 09/25/04. Drawing to within one half mile of the Exit 20A ramp departure for Maryland 175 (Little Patuxent Parkway) eastbound. Maryland 175 sees interchanges with Snowden River Parkway and Columbia Gateway Drive near the Exit 41 junction with Interstate 95. Photo taken 09/25/04. Exit 20A departs U.S. 29 (Columbia Pike) northbound for the eastbound beginning of Maryland 175 (Little Patuxent Parkway). Maryland 175 reaches the Anne Arundel town of Jessup eight miles to the east. Oakland Mills lies nearby at the crossroads with Thunder Hill Road. Photo taken 09/25/04. A full-cloverleaf interchange facilitates the movements between U.S. 29 and Little Patuxent Parkway. The parkway continues west from Columbia Pike to Wilde Lake, Governor Warfield Parkway, and the The Mall in Columbia. Governor Warfield Parkway stems southwest from the mall area to the Columbia Town Center. Photo taken 09/25/04. U.S. 29 northbound travels a short distance between Maryland 175 and the full-cloverleaf interchange with Maryland 108 (Exits 21A/B). Pictured here is a northbound reassurance shield. All Maryland freeways double as snow emergency routes, and are generally signed as such on reassurance shield assemblies. Photo taken 09/25/04. Maryland 108 (Old Annapolis Road / Clarksville Pike) meets U.S. 29 at Exits 21A/B near Columbia Hills. The east-west highway arcs 34.23 miles between Maryland 27 at Damascus and Maryland 175 near Waterloo. Maryland 108 meets the west end of the Patuxent Freeway (Maryland 32) at Clarksville 6.3 miles to the west. Photo taken 09/25/04. Maryland 108 (Clarksville Pike) westbound serves the Dorsey's Search and Harper's Choice communities via Exit 21B. Clarksville Pike also serves Centennial Park and Elioak to the west.

Exit 21B loops onto Maryland 108 (Clarksville Pike) westbound for Elioak and Clarksville. Use Clarksville Pike for Centennial Lane north for Centennial and Font Hill. Eliots Oak Road joins Maryland 108 with the town of Columbia to the south. Photo taken 09/25/04. Traffic merging onto U.S. 29 northbound from Maryland 108 forms an auxiliary lane for the Exit 22 off-ramp to Maryland 100. Maryland 100 constitutes a 22.05 mile long freeway between U.S. 29 east to Maryland 177 (Mountain Road) near Lake Shore and Jacobsville in Anne Arundel County. Photo taken 09/25/04. There is no direct access from U.S. 29 northbound onto Maryland 103 (Montgomery Road). Therefore drivers bound for Maryland 103 can use the Exit 1A interchange of Maryland 100 to Long Gate Parkway to access Montgomery Road and the adjacent park and ride lot. Maryland 103 parallels Maryland 100 between St. John's Lane and to Dorsey near the Anne Arundel County line. Photo taken 09/25/04. U.S. 29 northbound at the Exit 22 ramp departure for Maryland 100 eastbound. Maryland 100 ventures southeast from U.S. 29 through the suburbs of Howard and Anne Arundel Counties to Southgate and Pasadena.

Directional ramps shuttle U.S. 29 northbound travelers onto Interstate 70 east and Interstate 70 westbound motorists onto U.S. 29 south. This setup is like the U.S. 40 interchange to the south, with a standard cloverleaf configuration handling the remaining movements between the two highways.
