The project will widen 4.2 miles of Union Cross Road in Winston-Salem and Kernersville from Sedge Garden Road north of I-40 to just south of U.S. 311. It also includes constructing the area’s first diverging diamond interchange at I-40.
News and Updates
Currently, crews are grading and paving the roadway, as well as placing sidewalk, curb and gutter and driveways along the project. Traffic has shifted to the outside lanes, to allow for work on the median from I-40 to the Sedge Garden Road intersection, and to the newly constructed roadway from I-40 to U,S. 311/I-74, to allow for construction to the southbound lanes.
The new interchange with U.S. 311 is expected to open in late July of 2015. After the U.S. 311 interchange is complete, the contractor is going to move forces down to the U.S. 40 interchange to finalize the diverging diamond. If all goes well, this work should be completed by late August.

Project Overview and Purpose
The Union Cross Road Widening Project has two key components: widening work and the construction of a diverging diamond interchange.
- Widening Work - The $30.3 million project will widen 4.2 miles of the road from Sedge Garden Road north of I-40 to just south of U.S. 311. The majority of Union Cross Road will be widened to two lanes in each direction, but at the I-40/Union Cross Road interchange, it will be widened to three lanes in each direction.
- Diverging Diamond Interchange – Crews will construct one of North Carolina’s first diverging diamond interchanges at Union Cross Road and I-40. The DDI is unique, because it allows traffic moving in two directions to temporarily cross to the left side of the road. The DDI will provide drivers with easier access to I-40, and help eliminate the congestion and crashes that occur when vehicles back up on the ramps. To see how efficiently traffic flows through a DDI, watch the video below.
Construction on the project started on April 16, 2012, and final completion is set for Nov. 15, 2015. The contractor is Larco Construction – A Division of Branscome Inc. of Winston-Salem.
Currently, 25,000 cars travel along this 4.2-mile section of Union Cross Road daily, but that number is expected to rise to 41,000 a day by 2031. The improvements will prepare for and accommodate the future residential and commercial growth anticipated in the area. They will also enhance safety and help drivers get where they need to go more efficiently.
This video explains how traffic will move through the new diverging diamond interchange at Union Cross Road and I-40.

Resources for Local Property Owners
In many cases, it is inevitable that a certain amount of private property must be acquired. The displacement of homes and businesses is minimized to the extent practicable. The following brochures will answer questions about this process.
