Daytime Road Closures at Hampshire Road Beginning Wednesday, July 16

As part of the US 101 bridge widening at Hampshire Road, preparations are under way to begin pile driving the week of July 14. Pile driving is a common method of constructing bridge foundations. To support the bridge foundation, steel or concrete beams (known as "piles") are driven into the ground by a large hammer mounted atop a crane, until the beams reach a hard layer of earth beneath the foundation. Please be advised, this work may be loud and disruptive due to vibration and pounding.

WHEN/WHERE: In order for the contractor to set up the pile driving crane and other equipment, Hampshire Road underneath the US 101 freeway as well as the northbound US 101 Hampshire Road on- and off-ramps will be closed, from 9 p.m. Monday, July 14 to 6 a.m. on Tuesday, July 15.

Pile driving on Hampshire Road will begin during the day on Wednesday, July 16. Hampshire Road will be closed to through traffic at the US 101 freeway, daily between 9 a.m. and 4 p.m., Wednesday, July 16 through Friday, July 18. The US 101 freeway on- and off-ramps on Hampshire Road will remain open, however there will be no access on the roadway underneath the freeway. To avoid delays, motorists are encouraged to avoid the area and consider using alternate routes.
