US 401 Northbound Closure at U.S. 70/N.C. 50 South of Raleigh This Weekend

RALEIGH - The U.S. 70/N.C. 50 bridge replacement project at the intersection with U.S. 401 south of Raleigh will require the northbound lanes of U.S. 401 to be closed this weekend. The closure between Mechanical Boulevard and U.S. 70 westbound will be in effect from 9 p.m. on Friday through 6 a.m. Monday.

The closure is needed so crews can safely install storm drainage and new pavement along U.S. 401 under the U.S. 70 eastbound bridge.

Motorists will have a short signed detour, turning right on Mechanical Boulevard, and then left to get onto U.S. 70/N.C. 50 toward Raleigh.

The work is part of a $3 million contract awarded Dane Construction Inc. of Mooresville to replace the 61-year-old bridge over U.S. 401. It is considered structurally deficient and functionally obsolete. That means it is still safe, but has been in deteriorating condition and needed replaced, and that it was built to design standards that no longer can handle the increased traffic volume. The new bridge will have a higher clearance height over U.S, 401, and there will be wider shoulders on the roadway approaching the bridge. The new structure will also be on a new location just west of the current bridge to eliminate the need for an offsite detour in this heavily traveled area.

The new bridge is scheduled to be in place by Dec. 1, with additional vegetation work completed by May 30, 2014.

Because of the traffic volume through this intersection, almost all the work will be done at night. There can't be lane closures on U.S. 401, U.S. 70 or Mechanical Boulevard between 6 a.m. and 9 p.m. Monday through Saturday or between 10 a.m. and 6 p.m. on Sunday. In addition to this weekend, there will be other brief closures of U.S. 401 so the current bridge girders can be safely removed and the new girders put in place. That work can only take place between 9 p.m. on a Friday and 6 a.m. on a Monday.

This project is part of the NCDOT's $450 million state-funded bridge plan for 2011-13, which invests in preserving, repairing or replacing bridges statewide. For more information on this plan, visit our Bridge Improvement Program webpage.
