I-710 is a major north-south freeway section of the Los Angeles County highway network. The I-710 corridor study area stretches for 18 mi through the most heavily urbanized portion of the county. At the southern end sit the Ports of Long Beach and Los Angeles. At the northern end is East Los Angeles. The I-710 freeway is heavily congested with both passenger and freight traffic. Rapid growth in freight traffic from the ports and local population growth have led to increasing congestion, safety, and mobility problems in the corridor. Traffic volumes have overwhelmed the existing design capacity of the interstate, particularly at the interchanges. By 1985, portions of the freeway were experiencing delays of 3 or more hours hours per day. The situation threatened the local and regional economies as well as the health and quality of life of area residents, including many minority and disadvantaged populations. The ports are the economic lifeblood of the region, but local communities are increasingly affected by air quality, noise, aesthetic, and congestion concerns along the freeway. In response to these issues, the I-710 major corridor study was initiated in 2000. The purpose of the study was to analyze traffic congestion, mobility issues, and quality-of-life concerns along the corridor. The study would ultimately recommend a locally preferred strategy for improving the facility. The study followed a new bottom-up approach to planning that enabled all stakeholders and interest groups to identify needs and sponsor projects. This case study is discussed under the following headings: Background; Institutional Framework for Decision Making; Major Project Issues; Transportation Decision-Making Process and Key Decisions; Lessons Learned; and Conclusions.
