US 401 Northbound Closure at US 70/NC 50 In Raleigh This Weekend

RALEIGH - Northbound lanes of U.S. 401 will be closed between Mechanical Boulevard and U.S. 70 this weekend as work continues on an N.C. Department of Transportation project to replace the U.S. 70/N.C. 50 bridge over U.S. 401 south of Raleigh.

The closure is from 9 p.m. on Friday to 6 a.m. Monday. It will allow the contractor to safely complete storm drainage, paving and barrier work on the section of U.S. 401 northbound that goes under the bridge being torn down.

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

Dane Construction Inc. of Mooresville was awarded the $3 million contract to replace the 61-year-old bridge, which is considered structurally deficient and functionally obsolete. That means it is still safe for travel, but has been in deteriorating condition and needs to be replaced, and that it was built to design standards no longer used for bridges.

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. It will be on a new location just west of the current bridge, eliminating the need for an offsite detour.

The new bridge is expected 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. No lane closures are allowed on U.S. 401, U.S. 70 or Mechanical Boulevard between 6 a.m. and 9 p.m. Mondays through Saturdays, and between 10 a.m. and 6 p.m. on Sundays. In addition to this weekend, there will be other brief closures of U.S. 401 when the current bridge girders are removed and new girders put in place. That work can only take place on weekends between 9 p.m. Friday and 6 a.m. Monday.

This replacement 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.
