Capital Beltway High Occupancy Toll (HOT) Lanes
The Capital Beltway High Occupancy Toll (HOT) Lanes project (officially the 495 Express Lanes) is a public-private partnership (P3) between VDOT and Capital Beltway Express, LLC (a joint venture of Fluor and Transurban). The project extends from the Springfield Interchange (south) to just north of the Dulles Toll Road (14 miles). Previously, the Capital Beltway had four lanes in each direction. Improvements included:
- 14 miles of two new lanes in each direction
- First time introduction of High Occupancy Vehicles (HOV) lanes to the Capital Beltway and reliable transit options to the Beltway and Tysons Corner, Virginia
- Congestion-free network for carpools, vanpools, transit, and toll-paying motorists
- Replacement of more than $260 million of aging infrastructure, including more than 50 bridges and overpasses
- Construction of carpool ramps connecting I-95 with the Capital Beltway to create a seamless HOV network
Changes in the composition of the regional economy and shifts in employment patterns over the past 40 years have increased demand for all transportation facilities around the District of Columbia, particularly for roadways such as the Beltway that provide mobility between major suburban employment centers. Given that the last major improvements to the Beltway were completed in 1977, I-495 required substantial upgrades to keep pace with growing demand. According to the project’s website, the HOT lanes have considerably increased capacity, reducing congestion and cutting travel times by an average of 20 minutes per trip.
