Part of a highway in Rowan County will need to be closed this weekend to allow Norfolk Southern rail crews to replace a railroad crossing. Beginning at 7am December 4th, Jake Alexander Boulevard (U.S. 601/70) will be closed between Statesville Boulevard and Harrison Road. Work is expected to be complete by December 5th, weather permitting. A signed detour will be in place utilizing Brenner Avenue and Statesville Boulevard. An alternate detour route will use Statesville Boulevard, Majolica Road, Sherrills Ford Road and N.C. 150/Mooresville Road. Motorists should allow extra time for detours.
