Virginia officials and a private company have finalized a contract to build HOT lanes along Interstate 95, Gov. Bob McDonnell announced Tuesday.

Fluor-Transurban will pay $843 million and the state will fund $97 million initially to build the high occupancy toll lanes along 29 miles of the highway between Edsall Road in Fairfax County and Garrisonville Road in Stafford County. However, the state also said it plans to kick in $200 million more to expand bus service and build more than 3,000 new park-and-ride spaces.
