I-495/American Legion Bridge Transit and TDM Study
The purpose of the I-495/American Legion Bridge Transit/TDM Study is to identify a range of current and future multimodal solutions that can be implemented to reduce congestion, improve trip reliability and regional connections, and enhance existing and planned multimodal mobility and connectivity.
The I-495 Survey seeks to gain an understanding of commute choices in addition to driving alone. Click here to participate.
The I-495/American Legion Bridge Transit/TDM Study is being conducted separately from the NEPA process currently underway for the I-495 NEXT, American Legion Bridge, and MD P3 Program projects.
The American Legion Bridge opened in 1962 as part of the Capital Beltway (I-495). It was originally called the Cabin John Bridge and constructed as a six-lane facility. It was renamed the American Legion Bridge in 1969 and widened to 10-lanes in 1992 (8 through lanes and two merge or exit lanes.)
In 1965 the American Legion Bridge carried 48,000 vehicles daily. Today, daily traffic averages 235,000 vehicles and by 2040 it is projected to increase to 280,000.
The American Legion Bridge provides the only direct connection between the region’s two most populous counties — Fairfax (1,164,000) and Montgomery (1,020,000) — which between them are home to nearly 40% of the region’s population and jobs and 44% of its personal income. Residents of the region’s fastest-growing counties — Loudoun (368,000) and Frederick/City of Frederick (117,000) also depend upon the American Legion Bridge.
