US 15, north of I-66, is being widened to a 4-lane divided highway. You can read the PWC Project Report.

This project was divided into two sections, a northern section and southern section. Both sections will create a four-lane divided facility with median that will widen approximately 19,639 linear feet of Route 15. The northern section will widen Route 15 north of Dominion Valley to the intersection of Route 234. This section will include the realignment of Route 234 & Waterfall Road to create one intersection with Route 15. The southern section will widen Route 15 from north of Route 66 to north of Utterback Lane. Improvements will also include extending Heathcote Blvd. from its intersection with Rt. 15 east to its existing intersection with Old Carolina Rd, and widening Old Carolina Rd. from Heathcote Blvd. north to the existing Old Carolina widened section.

Thanks to Supervisor Stirrup's office for sending this out.
