North Beach Utility Relocation
This week the contractor began work on a sewer manhole, requiring the closure of the left lane for northbound traffic on Columbus Avenue between Union and Powell streets. Next week the left lane for northbound traffic will remain 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 will 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 at Union will remain open while this work is in progress. The northbound bus stop will be closed during construction hours.
