Construction on the Cesar Chavez Sewer and Streetscape Improvement Project will be completed a few months behind schedule in summer 2013, according to the SF Department of Public Works.

DPW’s Kris Opbroek said the streetscape portion will begin in the spring as completion of the sewer work moves west. When finished, the project will transform Cesar Chavez Street, from Hampshire to Guerrero Streets, with a wide planted median, bicycle lanes, and pedestrian safety improvements.

City staff and construction crews showcased the site last Friday as Mayor Ed Lee, who formerly headed the DPW, paid a visit to the project. It’s the largest yet under the city’s Great Streets Program, which has completed six streetscape projects since it began in 2005 and has another nine in the pipeline or under construction, according to a press release from the mayor’s office. Cesar Chavez, budgeted at $35.2 million, is the biggest project funded by the Great Streets Program to date.

The SFMTA is also developing plans for bike lanes on the eastern side of Cesar Chavez, just across “The Hairball”, after the mayor’s office pressured the agency into dropping a previous iteration of the plan in June.
