From the SF Department of Public Works:

The work which necessitated the two-lane closures on 19th Avenue is progressing faster than anticipated.

As of this afternoon, April 5, crews have completed the sewer work in the southbound lanes at Kirkham and Noriega intersections. We will proceed ahead of schedule with the two-lane northbound closure on 19^th Avenue in the Kirkham/19^th and Noriega/19^th intersections starting April 6.

Available traffic lanes along 19th Avenue at the intersections of Noriega and Kirkham streets will be reduced to accommodate an essential sewer replacement project. Work will take place 7 a.m. to 5 p.m., Monday-Friday. 

Crews have completed the southbound lanes and will now move onto northbound lanes, leaving just one lane open instead of the normal three in each direction. Northbound dates are now April 6-9. Motorists should expect delays of approximately 15 minutes from one end of 19th Avenue to the other and are advised to use alternate routes. 

The temporary reduction in lanes is needed to ensure the safety of construction crews, pedestrians and motorists while sewer replacement work is performed at the two intersections. Traffic control officers will be on site to direct people safely through the two intersections. 

We thank you for your patience as we work to maintain and improve our critical City infrastructure.
