Cost and schedule ►

Public outreach ►

This $12.7 million project will build eastbound and westbound passing lanes over a 1.5-mile segment of Route 3 between Potomac Mills and Flat Iron in Westmoreland.

When work is complete, Route 3 will become a four-lane undivided road from north of Route 639 (Winter Harbor Road) to east of Route 624 (Longwood Road). Route 3 will have four 12-foot travel lanes, and a 4-foot paved shoulder on each side.

Left turn lanes are being added on Route 3 eastbound at the intersection with Longwood Road, and on Route 3 westbound at Winter Harbor Road and Route 761 (Falls Hill Road).

Building additional travel lanes along this two-lane section of Route 3 will provide traffic with an opportunity to pass slower-moving vehicles.

A separate $1 million project to lengthen the right turn lane on Route 3 eastbound to Route 624 (Flat Iron Road) will be accomplished as part of this construction work zone and contract.
