Virginia Gov. Terry McAuliffe announced Wednesday that Express Lanes on Interstate 95 will extend to the Fredericksburg area.

The governor said the state accepted a proposal from Transurban to extend the Express Lanes about 10 additional miles, from Route 610 to Route 17 North. The project is part of the broader Atlantic Gateway initiative, a $1.4 billion package of improvements to road and rail service along the I-05 corridor.

The Express Lanes on I-95 and 395 together will combine for about 50 miles from Fredericksburg into the District. The Express Lanes will work exactly the same way as existing lanes, with all-electronic tolling and free access for carpoolers with at least three riders.

Construction is scheduled to begin in 2019 and would be completed by 2022.

Under the plan, Transurban would build and finance the Express Lanes and no state taxpayer money would be required. Funding came from a combination of private partnerships and a $165 million FASTLANE grant from the U.S. Department of Transportation.

“Expanding the Express Lanes 10 miles south will bring much-needed relief from the existing bottlenecks along the I-95 corridor, improve reliability for commuters and freight, enhance road safety and set up the regional economy for future growth,” Virginia Secretary of Transportation Aubrey Lane said.
