I‑97 (Maryland)

I‑97 (Maryland) is an Interstate Highway wholly within Anne Arundel County connecting Baltimore area corridors with the Chesapeake Bay waterfront at Arnold and providing a link between U.S. Route 50, I‑695, and MD 3. The route serves commuter, military, and maritime traffic between BWI Airport, Fort Meade, Naval Academy environs, and suburban communities such as Severna Park, Glen Burnie, and Parole. Designed as a limited-access spur, the highway interfaces with regional corridors including U.S. Route 301, Maryland Route 2, and the historic Baltimore and Annapolis Railroad corridor.

Route description

I‑97 begins at its southern terminus near Parole with an interchange connecting to U.S. 50 and MD 2 close to landmarks such as Anne Arundel County Courthouse, Anne Arundel Community College, and Rams Head On Stage. Proceeding north, the freeway crosses suburban sectors adjacent to St. John's College and the United States Naval Academy district, with access to Annapolis Mall and the Maryland State House via connecting arterials. The route intersects Maryland Route 665 and provides connections toward Glen Burnie, serving commercial nodes near Arundel Mills and BWI Business District as it approaches the Baltimore Beltway. Northbound lanes link to I‑695 at a major interchange that also facilitates movements to Fort Meade through MD 32 and to Baltimore via I‑95. I‑97 continues north through suburban neighborhoods, crossing tributaries of the Severn River before terminating near Arnold, with surface connections to MD 648 and local roads serving waterfront communities and marinas on the Chesapeake Bay.

History

Planning for the corridor that became I‑97 involved state and federal coordination amid the expansion of highway networks in the late 20th century, influenced by studies from entities such as the Maryland State Highway Administration, the Federal Highway Administration, and regional planning organizations including the Metropolitan Washington Council of Governments. Early alignments referenced existing routes like Maryland Route 3 and proposals tied to the development of Baltimore-Washington International Thurgood Marshall Airport and the growth of Fort Meade and Andrews Air Force Base. Construction phases in the 1980s completed the limited-access link, with dedication ceremonies attended by state officials from Maryland, members of the United States Congress, and representatives of Anne Arundel County. The designation as an Interstate required coordination under the Interstate Highway System policies and revisions to the American Association of State Highway and Transportation Officials route numbering. Subsequent upgrades addressed traffic growth from commuters to Baltimore and patrons of waterfront destinations, alongside safety projects influenced by standards from the National Highway Traffic Safety Administration.

Exit list

The exit sequence on I‑97 organizes interchanges providing access to regional arterials and institutions. Major exits include connections to U.S. 50/MD 2 near Parole and the Anne Arundel County government complex; accesses to Maryland Route 648, which serves Severna Park and the B&A Trail; interchange with MD 100 and MD 10 facilitating east–west movements toward Glen Burnie and Pasadena; and the interchange with I‑695 connecting traffic to I‑95 and the Baltimore Beltway. Further north, exits serve local routes into Arnold and waterfront corridors along the Severn River and Chesapeake Bay.

Future and planned improvements

Planned improvements on the I‑97 corridor reflect capacity, safety, and multimodal objectives coordinated among Maryland Department of Transportation, Anne Arundel County officials, and regional agencies like the Washington Metropolitan Area Transit Authority for broader connectivity studies. Proposed projects have included interchange reconfigurations to improve links to U.S. 50, ramp modernization near BWI Airport, and corridor management strategies to mitigate congestion from commuter flows to Baltimore and military installations such as Fort Meade and Naval Station Annapolis. Environmental assessments reference protections for the Severn River watershed and coordination with agencies including the U.S. Fish and Wildlife Service and the Maryland Department of the Environment. Funding discussions have involved federal programs administered by the Federal Highway Administration and state bonding measures debated in the Maryland General Assembly.

Auxiliary routes and designations

Auxiliary designations associated with the corridor include state-maintained connectors and frontage roads carrying Maryland Route numbers that interface with I‑97, as well as historical alignments of Maryland Route 3 and Maryland Route 2 repurposed as local arterials. The corridor's role in regional routing systems ties it to major federal highways like I‑95 and surface routes including U.S. 301 and U.S. 50, with administrative oversight by the Maryland Transportation Authority for tolled facilities in the region. Special designations for emergency routing and hurricane evacuation plans involve coordination with Federal Emergency Management Agency protocols and county emergency services.
