The next phase of The City’s $1.6 billion Central Subway project will begin Monday, when construction crews start relocating underground utilities in the Union Square and Market Street areas.
The utility relocation work at Union Square will last until June 2012, according to the San Francisco Municipal Transportation Agency, which operates Muni. As a result of the work, only one lane of traffic will be open on Stockton Street, between Sutter and Market streets, for large portions of the day.
Two lanes of traffic would be available from 3 to 7 p.m. during the weekday, and from 10 a.m. to 5 p.m. on the weekends. The rest of the time, only one lane will be open.
