Following a brief respite over the holiday weekend, crews are back at work today on the Upper Haight's ongoing infrastructure project. 

To recap: in the spring, construction in the Upper Haight resumed after a lengthy hiatus, during which the city investigated the series of gas leaks and sinkholes that plagued the project in 2015. The city ultimately chose to fire the subcontractor on the project, and once they found a new one, work resumed in March. 

Everything was copacetic until August, when SF Public Works announced that they were moving along ahead of schedule and planned to start work on the Central and Masonic blocks of Haight during August. Some local merchants balked, expressing concern that they would lose business during the summer months, when foot traffic in the Haight peaks. Sunshine Powers, owner of Jammin' on Haight, even considered a protest if construction severely impacted business, but ultimately, merchants decided against it.

Now, the project is about to move once again. This week, crews will start work on lateral water lines along Haight from Baker to Masonic, which should take about two weeks.

After that, they'll move to the Masonic to Ashbury intersection, to install and test the water main. The water main work will take "several weeks" to complete, so expect parking impediments and lots of noise and dust. 

The schedule, Public Works spokesperson Alex Murillo says, is also subject to change based on "rain, equipment breakdown, and/or unforeseen field conditions. We'll keep you abreast as things hum along.
