Maryland Route 175

Maryland Route 175 is a state highway in Maryland connecting communities in Howard County and Anne Arundel County, providing arterial links between suburban developments, military installations, and major highways. The route serves Columbia, Jessup, Fort Meade, BWI Airport, and Glen Burnie, intersecting corridors such as U.S. 29, Maryland Route 32, Maryland Route 100, and U.S. 1. Functioning as both a commuter boulevard and a freight connector, the highway supports access to facilities like National Security Agency, Fort Meade, BWI Marshall Airport, and business parks near Arundel Mills.

Route description

Beginning near Columbia and Howard County, the road proceeds southeast through mixed residential and commercial areas, intersecting U.S. 29 near Laurel and meeting Maryland Route 32 close to Benfield and industrial zones that serve Fort Meade. The highway traverses the Patuxent River watershed and enters Anne Arundel County, where it connects with Maryland Route 100 near Arundel Mills Mall and the Arundel Mills complex, providing direct routes to Baltimore–Washington Parkway and BWI Airport terminals. Eastward, the corridor passes near Northrop Grumman, Lockheed Martin, and other contractors before linking with U.S. 1 and crossing I-97/I-95 corridors en route to Glen Burnie. The roadway alternates between divided arterial sections and multilane boulevard segments, accommodating commuter, commercial, and military traffic destined for Fort Meade, NSA, and regional logistics hubs such as Hanson and Jessup.

History

The corridor evolved from 19th- and early 20th-century local roads serving farms and mills in Howard County and Anne Arundel County. Mid-20th-century growth tied to Fort Meade and defense contracting during the Cold War prompted upgrades, while the rise of planned communities like Columbia spurred suburbanization and arterial improvements. Completion of interchanges with U.S. 29 and Maryland Route 32 reflected broader transportation planning influenced by agencies such as the Maryland State Highway Administration and regional planning commissions tied to Baltimore–Washington Metropolitan Area. Later expansions coincided with construction of Maryland Route 100 and redevelopment around Arundel Mills after the 1990s, aligning with economic shifts toward retail, distribution, and aerospace contracting involving firms like Northrop Grumman, Lockheed Martin, and General Dynamics. The route's role in serving BWI Marshall Airport and access to Baltimore–Washington Parkway further integrated it into Metropolitan Baltimore's highway network.

Major junctions

The highway connects with several principal routes that serve regional traffic patterns: the junction with U.S. 29 near Laurel links to Howard County commuter flows; the interchange with Maryland Route 32 provides access toward Clarksville and West Friendship; the connection to Maryland Route 100 and proximity to Arundel Mills tie into retail and distribution access; intersections with U.S. 1 and interchanges offering moves to I-95 and I-97 integrate long-distance travel to Baltimore and Washington, D.C.; local connectors serve Glen Burnie and nearby employment centers including Fort Meade and BWI Airport.

Auxiliary routes

Several short spur and connector segments associated with the corridor provide localized access to industrial parks, military entrances, and commercial centers. These include ramps and service roads facilitating movements to Arundel Mills, access roads serving Fort Meade gates used by personnel to reach National Security Agency facilities, and frontage roads near Jessup providing connections to distribution centers utilized by firms such as Amazon and regional logistics operators. Many auxiliary links align with county-maintained collectors that feed into the state highway.

Future developments

Planned and proposed projects focus on capacity, safety, and multimodal integration to address commuter congestion and freight demands tied to BWI Marshall Airport and defense-related employment at Fort Meade and NSA. Proposals include interchange upgrades near Maryland Route 100, improved transit connections coordinating with Maryland Transit Administration, bicycle and pedestrian enhancements near Columbia and Arundel Mills, and corridor studies by the Maryland Department of Transportation to optimize freight routes serving Port of Baltimore-linked distribution. Coordination with regional plans for Baltimore–Washington Metropolitan Area growth, defense facility expansion, and private development near Arundel Mills will shape sequencing and funding.
