Install Rumble Bars on I-905 in San Diego County

Caltrans District 11 is proposing the installation of raised rumble bars at nine specific locations on eastbound SR-905 in San Diego County, spanning from the Airway Road undercrossing to the Otay Mesa Port of Entry. The primary objective of these installations is to alert drivers to traffic slowdowns or stoppages to improve road safety. All project activities will be conducted within the state right of way, and no separate staging location is required. The project, identified as 11-3B018, has been granted a Categorical Exemption under CEQA Class 1 and complies with NEPA requirements, as the work is classified as the repair and maintenance of existing public facilities with negligible expansion of use. A Notice of Exemption was filed on September 21, 2026. The project is managed by Caltrans in San Diego, California, with Emery McCaffery serving as the primary point of contact.
