Crystal Springs Road between Polhemus and Skyline/Hwy 35, in unincorporated San Mateo County just south of the Town of Hillsborough, will be closed be for 18 consecutive days from Monday, June 11th to Friday, June 29th .
The road closure is necessary to replace a regional water pipeline as part of the Crystal Springs Pipeline No. 2 project. Some additional construction work in this area will continue through October 2012.
During the closure, cars will be detoured onto Hwy 280. Bicycles will be detoured to Hillsborough city streets. Detour signage is now being posted along the routes and more information will be available online (including maps and alternate detour routes) later this week at: www.sfwater.org/SCT.
The road closure will be in effect for cars and other vehicles 24 hours a day, Monday through Sunday, from June 11 to June 29. Bicyclists only are expected to have through access on Sundays (however, the road will be closed for cyclists Monday to Saturday – including Saturdays June 16th and 23rd).
