Dulles Toll Road
The DTR ( Virginia Route 267 ) is 14 miles long with 4 lanes in each direction . It provides direct access to Dulles International . We have over 90 million revenue transactions each year . The Authority assumed operating control of the DTR in 2009 and uses a portion of the toll revenue to support the Silver Line Project .

The Dulles Corridor Metrorail Project , also known as the Silver Line project , is expected to open in 2021 and will bring high-occupancy Metro service to Dulles International . The Authority is responsible for the construction of the Silver Line . Toll revenue from the DTR covers 49 % of the project budget , with multiple entities covering the remaining 51 %. When construction is complete , the Washington Metropolitan Area Transit Authority ( WMATA ) will operate the Silver Line .
Sustainability Plan Creation
In 2019 , the Authority committed to developing a forward-looking sustainability plan beginning with a foundational implementation strategy of codifying sustainability policies and practices into our Design Manual and Master Plans . Of equal importance is a thoughtful strategy for the integration of sustainability policies and practices into existing and future airport lease agreements , service contracts , and purchasing decisions .
Integrate sustainability policies and practices into Design Manual , Master Plans , lease agreements and other contracts .
To that end , we have partnered with the National Renewable Energy Laboratory ( NREL ) 4 to facilitate a sustainability-focused update of our Design Manual and the development of our first Sustainability Plan . Using the Federal Aviation Administration ’ s ( FAA ) sustainability planning process 5 as guidance , NREL initiated the effort in 2019 , bringing together Authority staff and Board members and conducting sustainability planning charrettes at each airport . The FAA ’ s pilot sustainability planning program , through which several major U . S . airports have developed sustainability plans , resulted in guidance and best practice documentation , including a recommended process for developing such plans at airports , outlined in Table 1 .
