Virginia and Transurban have reached a deal on a 10-mile extension of I-95 express lanes. The three-year, public-private project, scheduled to begin in spring 2019, will add two reversible, dynamically tolled lanes from Stafford County to U.S. Route 17, south of Fredricksburg. Transurban also will provide $277 million for a new bridge across the Rappahannock River. Any remaining funds will be applied to other corridor transportation projects. Combined with Transurban’s current conversion of eight miles of existing HOV lanes along I-395 inside the Capital Beltway, the project will result in a 50-mile toll-lane corridor from outside Washington, D.C., to its metro area’s southernmost suburbs by the end of 2022.
