California Department of Transportation, District 8
Interstate 40 Median Regrading, Post Mile R25 to Post Mile R50
MND - Mitigated Negative Declaration
Present Land Use
The project would regrade the existing median slopes within the clear recovery zone of Interstate 40 (I-40) from Post Mile (PM) R25 to PM R50 between Newberry Spring and Ludlow, in San Bernardino County. The existing median slopes within the clear recovery zone would be regraded from existing 6:1 slope or steeper gradient to 10:1 or flatter to reduce the severity and the number of run-off-road accidents in the median on I-40. The project will also include drainage modifications to accommodate the flatter median slopes, the replacement of the existing Metal Beam Guardrails with Midwest Guardrail Systems, and improving existing California Highway Patrol crossings in the I-40 median. Approximately 1.9 miles along I-40 from PM R25.6 to PM R27.5 occurs within Troy Dry Lake and would not be improved as part of the proposed project.
