The Capital Beltway—also known as Interstate 495 (I-495)—is a 64-mile highway that surrounds Washington, D.C. and travels through the Maryland and Virginia suburbs. The Capital Beltway passes through Prince George's County and Montgomery County in Maryland as well as Fairfax County and the City of Alexandria in Virginia.

The highway is a loop around the whole of Washington, D.C. and one of the busiest in the nation. As a result, traffic can be rather unpredictable, so it's a good idea to get to know alternate routes to get around the region. When it comes driving on the Capital Beltway, it's helpful to know about the main exits from I-495 that grant you access to some of the best attractions in the capital region.

However, it's better to use a GPS device or app like Waza or Google Maps instead of a traditional map for specific directions as road closures and detours often happen along the route. Also, be sure to check traffic reports and detours before you plan your travel for the day as these driving conditions can often change daily.
