On Thursday, May 27th, the Los Angeles County Metropolitan Transportation Authority (MTA) will consider approving the preparation of a comprehensive State Route 710 corridor study, which will include alternatives and environmental impacts of a project that would close the 4 mile gap in the Long Beach (710) Freeway between Alhambra and Pasadena. Alternatives will include improvements to surface streets, construction of a surface freeway and a series of tunnels. The project would be subject to environmental review under the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA). The 710 Freeway Project would also have to comply with the Clear Air Act, Clean Water Act and Historic Preservation Act. The tunnels alternative[s] will present unique issues concerning groundwater, contaminated soils and active fault lines.

The 710 Freeway was originally planned to extend from Long Beach to Pasadena. The Long Beach to Valley Boulevard segment was opened in 1965. However, since that time the segment between Valley Boulevard and Pasadena has been stalled by public controversy and court actions, resulting in the “710 gap.” Opponents argued that completion of the Valley View to Pasadena segment would require destruction of hundreds of homes and some historic properties. Residents in other areas complained about noise and air pollution caused by heavier traffic on other freeways and surface streets because of 710 gap, and supported completion of the freeway. In 1999 a U.S District Court Judge ruled that the project, as then proposed, violated the Clear Air Act, NEPA and the Historic Preservation Act. Rather than remedy the violations, the Federal Highways Administration (FHWA) rescinded its Record of Decision (ROD) and the California Transportation Commission withdrew its Notice of Determination.
