Major Traffic Change: I-495 North Left Exit to I-66 West to Close

Fairfax motorists will have to change some long-term habits in the next few days as a familiar, though often troublesome, Beltway ramp closes forever.

VDOT says that on or about Sept. 30, Exit 49C, the left exit from I-495 north to I-66 west will permanently close to traffic. Drivers will be required to use the existing right exit ramp, Exit 49A, I-66 west. The right exit ramp will have two lanes to accommodate the additional traffic.  

Motorists will need to be in the right lane on I-495 north as they approach the I-66 interchange to access Exit 49A, I-66 west. The merge point onto Exit 49A, I-66 west has been relocated to before the I-66 overpasses.

The closure of the left exit ramp is necessary to shift traffic to the new Beltway outer lanes and allow progress to begin on a new HOT Lanes access ramp that will be built in place of the existing left exit for I-66 west.

Motorists are encouraged to use caution in this area as a new traffic pattern will be in place. This work is part of the Capital Beltway High Occupancy Toll (HOT) Lanes Project.
