Northbound I-495 Traffic Shifted to New Beltway Alignment

Reminder: Traffic on all four general-purpose lanes of northbound I-495 (Capital Beltway Inner Loop) was shifted onto newly constructed outer lanes between just south of Old Dominion Drive and the George Washington Memorial Parkway. This shift enables crews to begin construction of the new express lanes in the center of the Beltway. Lanes on southbound I-495 (Capital Beltway Outer Loop) in the project corridor are planned to start shifting in early June.

New Ramp Alignment for Traffic Exiting George Washington Memorial Parkway to Southbound I-495 and Georgetown Pike (Exit 44) and Southbound I-495 Traffic Exiting at Georgetown Pike (Exit 44)

Reminder: Traffic was shifted to a new ramp alignment located on the outer edge of the Beltway that runs parallel to southbound I-495 (Capital Beltway Outer Loop) between George Washington Memorial Parkway (GWMP) and Georgetown Pike. Drivers exiting northwest GWMP to southbound I-495 now stay in the right lane of the ramp and merge onto I-495 just south of the Georgetown Pike Bridge and motorists heading to Georgetown Pike (Exit 44) now remain in the left lanes of the ramp to reach the exit. Southbound I-495 Exit 44 collector road traffic now enters the new ramp alignment just after Exit 43 for GWMP and exit left to access Georgetown Pike (Exit 44).

Drivers should pay close attention to signage and lane markings, and use caution while getting acclimated to these new traffic patterns.

New Exit Ramp for Northbound I-495 Exit to Westbound Dulles Toll Road

Reminder: Motorists traveling on northbound I-495 heading for westbound Dulles Toll Road must take a new, earlier exit. The new exit ramp is located about one-third of a mile ahead of the old, closed Exit 45. To facilitate this new traffic pattern, I-495 has been reduced from four to three lanes for approximately one-half mile near the Dulles Corridor interchange.

Westbound George Washington Memorial Parkway to Southbound I-495

Reminder: The ramp from westbound George Washington Memorial Parkway to southbound I-495 (Capital Beltway) was reduced from two lanes to one lane to make room for a construction vehicle haul route that will be separated from traffic by a physical barrier. This traffic change will be in effect throughout construction on the 495 NEXT project.
