The Interstate 85 northbound ramp to N.C. 150 in Davidson County is expected to be closed today starting at 7 a.m. so that work can begin on the first phase of the I-85 Corridor Improvement Project, the North Carolina Department of Transportation said.
The closure is necessary to build a new interchange that will improve access to N.C. 150, DOT said.
The ramp will remain closed until the project is finished in January 2013.
During construction, a detour will be in place for motorists traveling north on I-85. The detour will take motorists past the closed ramp to Exit 85 toward Clark Road. Detour signs on Clark and Salisbury roads will lead to N.C. 150.
The interchange work is part of a $136 million contract awarded to Flatiron-Lane, a joint venture of Flatiron Constructors Inc. and The Lane Construction Corp., to widen nearly 3 1/2 miles of I-85 from four lanes to eight and replace eight bridges, including the I-85 bridge over the Yadkin River.
