With winter behind us and the start of a new season ahead, it's time to check in on the Upper Haight transit improvement and pedestrian realm project.

Six months into a projected total two years of construction, the first phase of the project is approaching its originally scheduled end, in April.

Phase I of the project is focused on replacing sewer mains and laterals along upper Haight Street; crews are currently at work on the 1500 block of Haight (from Ashbury to Clayton) and the intersection of Haight and Cole.

Though a few days of work were lost to rain, SF Public Works spokesperson Alex Murillo said the phase's completion is actually projected to stick pretty close to the original plan. It's shooting for an early May wrap-up, he said, "barring additional rain delays or unforeseen field conditions."

But before phase one draws to a close, some weekend work is on the horizon.

"One of the last segments of work under Phase I will include [the] re-lining of the sewer main on Haight Street between Cole North and Cole South," Murillo said via email. "Crews will need to work continuously over a weekend to re-line that stretch of pipe."

On that weekend (exact date TBD), locals can expect minor surface interruptions, like plate and manhole replacement, trucks, and generators.

But from there, it's on to phase two, which includes surface improvements, lighting, cosmetics, new sidewalks and design features.

"We're anticipating to start in mid- to late May," Murillo wrote. "We anticipate starting work near the Central Avenue intersection."
