Warm weather allows for projects and regular scheduled maintenance to occur along Crystal Springs Regional Trail. We thank you for your patience with trail closures as we performed annual mowing along the trail earlier this summer. Learn about current and upcoming project-related closures below and see a map of all trail closures.

Paving & Culvert Maintenance, June 13 - September 30

From June 13 through September 30, San Mateo County Public Works will perform critical trail maintenance by replacing 16 culverts and repaving and re-striping a 3-mile portion of the Sawyer Camp segment. During the project, a 3-mile portion of the 7.2-mile Sawyer Camp segment will be closed 7 days a week. The closed portion spans from the Hillcrest Blvd gate to Tracy Dam (approximately a half mile south of the Jepson Laurel).

PG&E Gas Transmission Project, July 25 - November 23

From Monday, July 25 through Wednesday, November 23, PG&E will excavate a portion of the San Andreas segment to inspect the subsurface gas transmission line and to install new monitoring and reporting devices. This is part of PG&E's regional efforts to improve its management systems. During the project, a 0.5-mile portion of the 2-mile San Andreas segment will be closed 7 days a week. The closed portion spans from the northern entrance at San Bruno Ave to the electric gate a half a mile south.

Please note: Trail closures go into effect the evening before, at 6:30pm.
