If you’re on a road trip to Washington, DC or have rented a car at the airport, you’re probably wondering how to drive on what locals call the Capital Beltway. It’s actually Interstate 495, a 64-mile highway that circles Washington. The highway passes through Prince George and Montgomery counties in Maryland, and Fairfax County and the city of Alexandria in Virginia.
So I-495 is the Capital Beltway, or just “The Beltway.” The two directions of travel, clockwise and counter-clockwise, are known as the “inner loop” and the “outer loop.” Knowing the terminology is the beginning of knowing how to navigate this circular path.
Arriving in Washington, DC
Access to Washington, DC is via I-270 and I-95 from the north; I-95 and I-295 from the south; I-66 from the west; and US Highway 50 from the west and east.
The most scenic routes from I-495 into Washington are via George Washington Memorial Parkway along the Virginia side of the Potomac River, Clara Barton Parkway along the Maryland side of the river, and Baltimore-Washington Parkway, approaching the center from the northeast.
I-495 History
Construction of the Capital Beltway began in 1955 as part of the Interstate Highway System that was created in the Federal Aid Highway Act of 1956. The first section of the highway opened in 1961, and the highway was completed in 1964. Originally , I-95 was planned to serve central Washington from the south and north, intersecting the Beltway in Virginia and Maryland. However, the plan was canceled in 1977, and the entire portion of I-95 within the Beltway from the south running north to downtown Washington, DC
it was reassigned as I-395.
By 1990, the east side of the beltway was dual-signed I-95 / I-495. Exits were renumbered based on mileage from the I-95 entrance in Maryland at the Woodrow Wilson Bridge. Understandably, this was confusing.
Traffic congestion on I-495
The explosive growth of homes and businesses in the suburbs of Maryland and Virginia has created a lot of traffic in the region, especially on the Capital Beltway. Despite numerous expansion projects in recent decades, heavy traffic is an ongoing problem.
The intersections on the capital bypass that rank as the “worst bottlenecks in the nation” are the interchange at I-495 and I-270 in Montgomery County, Maryland; the interchange at I-495 and I-95 in Prince George’s County, Maryland; and the Springfield interchange, where I-395, I-95 and I-495 meet.
Many outlets provide traffic reports with real-time information including details on accidents, road construction, chemical spills, and the weather. A wide range of transportation alternatives is available for travelers who want to avoid the ring road altogether.
I-495 Driving Tips
Driving on the Capital Beltway and other interstate highways in the Washington DC area can be a headache. You can lower your chances of having problems by staying informed and planning ahead.
- Plan your route in advance and in time to move to the right lane when exiting. In heavy traffic, it can be difficult to change lanes and may take longer than expected.
- Traffic can be unpredictable. Be flexible and ready to use an alternate route if necessary.
- Avoid traffic congestion by traveling during periods other than rush hour. Washington rush hour is generally 6 to 9 am and 4 to 7 pm, Monday through Friday.
- Expect reinforcements during rush hour at the Woodrow Wilson Bridge and the American Legion Bridge.
- Construction can cause delays at any time of the day. Check state transportation websites before you leave to find out where construction is taking place.
Virginia Express Lanes en la I-495
The Virginia Department of Transportation opened high occupancy toll lanes (HOT), or express lanes, in Northern Virginia in 2012. The project added two lanes to I-495 in each direction from west of the Springfield interchange to north of Dulles Toll Road and included the replacement of more than 50 bridges, overpasses and major interchanges.
Drivers of vehicles with fewer than three occupants must pay a toll to use these express lanes. An EZ Pass transponder is required to enable electronic toll collection. There are no tolls for buses, public transportation vehicles of at least three people, motorcycles and emergency vehicles.
If you are visiting from out of town and have an E-ZPass from another area, you can use these express lanes. Signs leading to and within toll lines have an E-ZPass logo that tells you that you need an E-ZPass. Fortunately, there are 15 states that use E-ZPass and more than 26 million E-ZPass devices in circulation, making it convenient for many visitors to use the express lanes.
If you don’t have an E-ZPass device, you can’t drive on the express lanes.
