- Crash Video showing importance of placement of cable barriers in median (4MB MPEG)
This video shows the result of placing cable within the 1′ to 8′ range of ditch centerline.
FHWA recommends that barrier NOT be placed in the 1′ to 8′ zone of bottom of median. For more information:

Funding Resources for Cable Barrier
Often DOT engineers want to put in barriers but do not know of funding sources or how to go about getting it. We hope the following information can help.
- FHWA description of the Federal-aid reimbursement eligibility process for roadside safety hardware
- SAFETEA-LU and Guardrail Dollars available to You Slideshow (PPT)
- ATSSA’s SAFETEA-LU Safety Program Summary
- States must develop a Strategic Highway Safety Plan (SHSP) to be eligble for funding under SAFETEA-LU
- ATTSA’s Low Cost Local Road Safety Solutions (See pages 35-38). While SAFETEA-LU funds are to be administered by state Departments of Transportation, Congress has directed that they be targeted at rural roads that have fatality rates that exceed statewide averages. ATSSA developed this tool to help you stretch your safety dollars.
- Common Funding Sources for Safety Improvement Programs
SAFETEA-LU provides $90 million annually over four years as a set-aside under the Highway Safety Improvement Program (HSIP).
