N.C. Department of Transportation contractors will replace the superstructure of the bridge on Williams Road over U.S. 421 in Lewisville in Forsyth County.
The superstructure is the portion of the bridge that spans between the supports.The current superstructure was damaged by an oversized load. By replacing it instead of just repairing the damage, the Department is able to increase the vertical clearance over U.S. 421. This week crews will begin performing work on the portions of the bridge that will remain in place and will be preparing for the closure of Williams Road next month. Beginning Monday, Feb. 9, Williams Road will be closed to traffic between the ramps at the bridge. Williams Road should be reopened by Aug. 17 and the project complete by November 24.Motorists travelling northbound on Williams Road towards Lewisville can use a signed
detour route along U.S. 421 South to Lewisville-Clemmons Road and take the ramp onto U.S. 421 North back to Williams Road.Motorists travelling southbound on Williams Road towards Clemmons can use a
detour route along U.S. 421 North to Shallowford Road and take the ramp onto U.S. 421 South back to Williams Road.During the construction project, lane closures can be expected on U.S. 421. The closures will take place outside of the morning and evening rush hours depending on direction of travel. Full closures of U.S. 421 may also occur at night between 9 p.m. and 6 a.m. During these closures, traffic will be routed off the ramps at U.S. 421 and motorists will travel around the traffic circles and back onto U.S. 421.
