Project Description:

The proposed project consists of re-grading the existing nonstandard I-40 median cross slopes within the 30-foot clear recovery zone from existing, which vary from 2:1 to 6:1 or steeper, to 10:1 or flatter. The proposed improvements would require substantial fill material and modification of existing drainage facilities within the median. Drainage modifications and improvement work would consist of reconstruction of existing offsite drainage facilities by extending the storm drain in the median

The proposed project area extends along a 29.6-mile distance between PM 125.0 to PM 154.6 on U.S. I-40 in the unincorporated territory of San Bernardino County, California. The proposed project spans from approximately 16 miles west of the City of Needles to the California/Arizona State Line. It is located within the United States (U.S.) Geological Survey (USGS) 7.5-minute series topographic quadrangles of West of Flattop Mountain, Flattop Mountain, Bannock, Needles NW, Needles SW, Needles, Topock, and Whale Mountain.  The proposed project crosses through several Ranges and Townships.

Public Notice of Availability of an Initial Study (with Mitigated Negative Declaration) 

What's Being Planned

The California Department of Transportation (Caltrans) proposes to regrade the existing median cross slopes within the 30-foot clear recovery zone (CRZ), from existing 6:1 or steeper gradient to 10:1 (or flatter) on Interstate 40 (I-40) from 4.5 miles of Homer Wash bridge near the Town of Ludlow (post mile [PM] R125.0) to the California/Arizona State Line (PM R154.6) in rural San Bernardino County.  Providing flatter slopes and upgrading existing highway roadside design features within the project limits is expected to reduce the number and severity of collisions in the median.  This would improve the roadway safety of the traveling public.

Why This Ad?

Caltrans has studied the effects this project may have on the environment. Our studies show it will not significantly affect the quality of the environment. The report that explains why is called an Initial Study (with Mitigated Negative Declaration). This notice is to tell you of the preparation of the Initial Study (with Mitigated Negative Declaration) and of its availability for you to read, and to also offer the opportunity to request a public hearing or to provide comments, and the intent to adopt this Mitigated Negative Declaration.

What's Available

Maps for the Initial Study (with Mitigated Negative Declaration) and other project information are available for review and copying at the following locations: 

  • Needles Branch Library, located at 1111 Bailey Avenue, Needles, CA 92363 (posted hours of operation for the Needles Branch Library: Monday, Tuesday, Wednesday: 11 am to 7 pm; Thursday: 10 am to 6 pm; Saturday: 9 am to 5 pm; Fridays and Sundays: closed).
