Caltrans Logo

The California Department of Transportation (Caltrans) proposes to construct auxiliary lanes to connect the entrance and exit ramps between the Temecula Parkway and Winchester Road interchanges from Post Mile R3.5 to Post Mile R6.8 in Riverside County. A Draft Initial Study (IS) with Proposed Mitigated Negative Declaration (MND) has been completed for the project. Caltrans is the lead agency under both the California Environmental Quality Act (CEQA) and the National Environmental Policy Act (NEPA).

The Draft Initial Study with Proposed MND and other project information is available for review and copying at the Caltrans District 8 Office (464 W. 4th Street, San Bernardino, 92401) on weekdays from 8 am to 4 pm.  Due to COVID-19 protocols, please provide a minimum 24-hour notice prior to visiting the District office to view available documents. To request a copy of the IS-MND, please contact Antonia Toledo, Senior Environmental Planner, at antonia.toledo@dot.ca.gov or call (909) 501-5741. The deadline to submit public comments is January 30, 2023.
