With an overall goal of reducing travel times and traffic congestion, AECOM is working to increase capacity on the SR-91 and improve the daily commuting experience of residents between Orange and Riverside counties in the Greater Los Angeles Area.
Congestion along a 15.9-mile portion of the eastbound road is routinely ranked among the worst five areas in the nation. To address the issue, AECOM is providing overall design and construction support for improvements to this major east-west corridor. The project includes additional tolled express lanes, general purpose lanes and connectors, as well as improvements to seven interchanges, 32 bridges, numerous ramps and local streets.
