In January 2017, high floodwaters washed out the culvert where Pinole Creek crosses Alhambra Valley Rd. Work began on June 12, 2017. Repairs entailed installation of a 60' bridge with pedestrian and bicycle paths. A bridge will allow easier access by fish to the upper watershed. Construction was completed November 2, 2017.

A bridge was completed by fall of 2017.
