As the Upper Haight infrastructure and pedestrian realm project approaches the completion of its first phase — on schedule, no less — it's heading into a three-day stint of around-the-clock work at the corner of Haight and Cole streets.

Crews will be relining the sewer under the Haight and Cole intersection, a job that commenced at 7 a.m. today, May 1, and will continue nonstop until the end of Friday, May 3.

All the work will be conducted underground, but will require a full aboveground retinue of equipment and trucks, causing disruptions to parking and transit. 

The 37-Corbett, 43-Masonic and N-Owl bus lines will be rerouted from their usual Cole Street stop up to Belvedere. Parking on the affected blocks of both Haight and Cole streets will be off-limits, to make way for generators, sewer pumps, spot lights, and water trucks.

Phase two, still on track to kick off in late May, will entail streetscape enhancement, including "pedestrian-scale lighting, tree planting, sidewalk replacement, curb ramps and bulb-outs, bus bulbs, conduit work, traffic signal installation/replacement, and repaving of Haight Street between Stanyan street and Buena Vista West," according to SF Public Works. We'll keep you posted on that work when it begins.
