"The significant congestion on the I-605/SR-91 system interchange is expected to increase in the future if physical and operational improvements aren't made to the roadways," said Anna Lantin, P.E., Michael Baker International Senior Vice President and West Region Director. "Michael Baker's expertise designing highway infrastructure to reduce congestion, enhance safety and operations and minimize environmental impact, will ensure We Make a Difference for the community and region by improving the livelihood of commuters and making freeways safer to promote more efficient movement of goods across Southern California."
The Michael Baker team identified that congestion in this area is the result of insufficient SR-91 freeway mainline capacity, inadequate capacity of the existing two lane connector for the westbound SR-91 to northbound and southbound I-605, and closely spaced freeway entrance and exit ramps.
In 2011, Metro selected Michael Baker to analyze congestion and improvements needed for traffic Hot Spots along more than 40 miles of the I-605, I-405 and SR-91 freeways in Los Angeles County. The completed $5.7 million feasibility study incorporated 19 different traffic-model scenarios and included the Michael Baker team's recommendations to improve five freeway-to-freeway system interchanges, 35 local arterial street interchanges, mainline freeway general purpose lanes, HOV direct connectors and arterial improvements through numerous cities.
In the next phase of that project, Metro contracted with Michael Baker to prepare additional study documents for two of the major system interchanges at I-605/SR-91 and I-605/I-5. These Project Study Report-Project Development Support (PSR-PDS) documents included traffic modeling, analysis and geometric plans for 20 miles of freeway widening for three separate alternatives, including concept cost estimates.
"Michael Baker's thorough understanding of the project since its inception lets us advance it at full speed," said Steve Huff, Michael Baker Transportation Practice Lead, Southern California. "In this way, our unique knowledge of the corridor's issues and challenges identified in the feasibility study will aid us in analyzing and identifying the necessary improvements."
The project approval phase is scheduled for completion in March 2018, with construction anticipated to begin in 2021.
