Upcoming Traffic Revisions for Columbia St on Saturday, April 21 and Tuesday, April 24

SDOT is advising travelers that Columbia St will be reduced to one travel lane between 2nd and 3rd Avenues on Saturday, April 21, between 8 a.m. and 6 p.m. and Tuesday, April 24, between 9 a.m. and 3 p.m. as work continues on the Columbia St 2-way Transit Corridor Project.
