Document Description
The purpose of this project is to construct concrete barrier, double thrie beam barrier, and Midwest Guardrail System as upgrade end treatments and crash cushions to comply with Manual for Assessing Safety Hardware (MASH) standards to improve safety by reducing colission severity and reduce to potential of run-off road accidents at four locations identified by the Office of Traffic Safety. The Office of Traffic Safety has identified four locations that need standard roadside safety systems to reduce collision severity and reduce run off road accidents. At location 1, the existing bent columns are unprotected fixed objects that are creating blunt end conditions for motorists traveling along West Grand Line Road in both directions at both eastbound and westbound I-580 Grand Line Undercrossing structures. Existing metal beam guard railing do not meet current safety standards within the project limits at locations 2 and 3. Location 4 has a total accident rate (fatal and fatal + injury) that is two times the average for a similar ramp facility. List of Locations: Location 1: 04-ALA580 PM R1.48 Grant Line Road Underscrossing - West Grant Line Road Location 2: 04-CC-680 PM R4.18 NB I-680 Onramp from Crow Canyon Road Location 3: 04-CC-160 PM 0.00 Victory Highway Separation Location 4: 04-CC-680 PM 24.12 NB I-680 Offramp to Waterfront Road
