Road Improvements Coming to Oak Grove Drive and Berkshire Place

To protect and preserve the local roads used by haul trucks during the Devil’s Gate Reservoir Restoration Project, LA County Public Works will perform microsurfacing work along Oak Grove Drive and a portion of Berkshire Place in the cities of La Cañada Flintridge and Pasadena.

Microsurfacing is a paving operation that is similar to slurry seal. The process consists of the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and chemical additives to an existing asphalt concrete pavement surface. The application hardens quickly and can be used when conditions would not allow slurry seal to be successfully placed. Streets with substantial shade or a relatively high volume of traffic are good candidates for microsurfacing.

New striping will be installed along treated road segments with additional signage and pavement markings added for improved safety for all roadway users. Work will be performed April 6-10, during the La Cañada Unified School District Spring Break, with final roadway striping performed by April 11.

Working hours are from 7 am to 5 pm, and traffic may be reduced to one lane in each direction during construction. Call the project hotline at (626) 458-2507 with any questions or visit the project website at devilsgateproject.com.
