This is a proposed freeway widening project to help mitigate traffic congestion along the WB SR-91 from I-605 to Artesia Blvd. MA Engineering was responsible for the design development of Stage Construction and Traffic Handling for the work to be completed along the SR-91 from the I-605 to Artesia Blvd. MA Engineering identified constructability issues with the original design and further developed a revised design that would avoid the identified constructability issues and comply with current Caltrans requirements.
