ISSUE
The Eastbound 91 Atlantic to Cherry Safety Improvements Project (Project) is 1.4-mile project that improves the operations and safety of the corridor by elimination of the lane reduction at the gore of the SB I-710 to eastbound SR-91 connector and the reconfiguration of the eastbound on-ramp from Atlantic Avenue and the eastbound off-ramp to Cherry Avenue. The improvements also include an additional eastbound auxiliary lane from Atlantic Avenue to Cherry Avenue by reconfiguring Atlantic Avenue Undercrossing, Myrtle Avenue Undercrossing, Orange Avenue Undercrossing, and Walnut Avenue Undercrossing. All of these improvements provide operational and safety improvements that would reduce truck congestion and increase safety on the heavily used freight corridor.
The specific improvements chosen were informed by an analysis of mainline and ramp collision history, performed by Caltrans Traffic Accident Surveillance and Analysis System. For the area within this Project, total accident rates range from 30% to 73% higher than the total statewide average accident rate, and fatality rates in this area exceed statewide averages by 35%, all highlighting the need for these safety-critical improvements. Data associated with these accidents show that accidents were indicative of ramp and auxiliary lane congestion due to weaving patterns and/or existing ramp and intersection geometry. The safety improvements to the SR-91 Corridor are expected to avoid one fatality, 366 injuries, and 646 crashes over the 20-year study period.
This oral report will include an update on the current status of the project, including Metro's coordinati...
