The City of Syracuse reopened West Onondaga Street between South Salina Street and West Street Thursday night. The road closed early Thursday afternoon when a concrete sidewall on the New York Susquehanna & Western Railroad viaduct along Clinton Street in downtown Syracuse collapsed. Repair work on the viaduct will continue to the north of the steel railroad bridge over West Onondaga Street today. Crews cleaned up debris along Clinton Street Thursday evening, but the 500 block of the road will remain closed until further notice.
