A plan to add $100 million of transit upgrades to a major HOT lanes project along Interstate 95 has been scrapped, with Virginia officials slashing plans to add four bus rapid transit stations, create new bus routes, and upgrade Metro and Virginia Railway Express facilities. The resulting project is expected to lead to more congestion inside the Beltway, according to a state report. And now the state will pay about $100 million for four parking lots and a ramp on what’s left of the once-touted private-public partnership to build the high-occupancy toll lanes.
