The project adds HOT Lanes within the median of the Capital Beltway and new ramps at various interchanges that allow drivers using the inside lanes access to the intersecting roadways. The project exists in four phases: Tysons Corner / McLean - the Beltway north of Interstate 66 Merrifield - Interstate 66 interchange Annandale - the Beltway south of Interstate 66 Springfield Interchange Work between 2008 and 2011 involves constructing four new outer lanes on the Beltway and the demolishing and reconstruction of all Interstate 495 interchanges. Work between 2011 and 2012 shifts traffic onto the new outer lanes while crews construct two inner HOT lanes. The project completion is expected in 2013. See the project web site for more details.
