Construction Info

Overview


Construction began in summer 2008 on 14 miles of HOT lanes - two lanes in each direction - that will stretch from the Springfield Interchange to just north of the Dulles Toll Road in Virginia.

The Capital Beltway HOT Lanes project will deliver a package of transportation improvements that will be the most significant enhancement to the Beltway in more than 30 years.
