This week the contractor continued construction to replace a sewer manhole. Next week construction to relocate a water line will be underway, and the left lane for northbound traffic on Columbus Avenue between Union and Powell streets will be closed during construction hours (Monday thru Friday, 7 a.m. to 3:30 p.m.). To facilitate construction in the median of Columbus Avenue, the southbound lanes may be shifted toward the western side of the street. Both southbound lanes will remain open, and traffic controls will be in place to facilitate safe travel through the area.
The southbound bus stop on Columbus Avenue at Union Street will remain open while this work is in progress. The northbound bus stop will be closed during construction hours. In addition, the westbound bus stop on Union Street at Columbus Avenue may be temporarily relocated about 100 feet east of its regular location.
Work may be underway in the intersection of Columbus Avenue and Union Street, and the crosswalk crossing Columbus Avenue on the north side of the intersection may be impacted.
