HistorySR-710 Map

The 23-mile stretch known as the I-710 was completed in 1964, leaving a 4.3 mile gap (SR-710) between the I-10 and I-210 freeways. Over the years, planning efforts continued for the completion of SR-710 as originally intended. However, the SR-710 Gap Closure Project, evolved to evaluating alternatives that would relieve congestion on local streets and address community concerns. 

On May 25, 2017, the Metro Board voted to eliminate the SR-710 North extension between Alhambra and Pasadena. The Metro Board also redirected $708 million in Measure R funds to local road improvements to provide traffic congestion relief for the San Gabriel Valley region. Projects need to support the purpose and need of the Gap Closure Project to relieve congestion on local streets along the SR -710 alignment between Interstates 10 and 210, with the highest priority for projects proximate to the Interstate 10 freeway.

Under two Metro funding cycles, Monterey Park received an allocation of approximately $100.3 million for the following SR -710 North Mobility Improvement Projects (MIP)

Project Updates

CIP 96023-Garfield Avenue Capacity Improvement



Project Manager: Ziad MazboudiStatus: In DesignProject Location (map)
The project involves the widening of Garfield Avenue between Hellman Avenue and Hilliard Avenue. The improvements include additional lanes (a southbound lane and a center two-way left-turn lane) to increase capacity, improve traffic flow, and reduce congestion along Garfield Avenue, which will continue to worsen over time without improvements. 

CIP 96024-Atlantic Avenue Capacity Improvement



Project Manager: Ziad MazboudiStatus: In DesignProject Location (map)
The proposed project involves improvements to Atlantic Boulevard from Hellman Avenue to Garvey Avenue. The improvements include additional lanes to increase capacity, improve traffic flow, and reduce congestion along Atlantic Boulevard, which will continue to worsen over time without improvements. 

CIP 96025-Ramona Road Capacity Improvement

 
Project Manager: Ziad MazboudiStatus: In DesignProject Location (map)
The project limits are Ramona Road off-ramp on I-710 northbound (located south of I-10 Freeway) to Corporate Center Drive, and Corporate Center Drive from the I-710 off-ramp to approximately 300 feet south of the I-710 off-ramp. The improvements include an additional lane on the off-ramp to increase capacity, improve traffic flow, and reduce congestion at this location, which will continue to worsen over time without improvements.


CIP 96026-Adaptive Traffic/Traffic Responsive Control System




Project Manager: Ziad MazboudiStatus: In DesignProject Location (map)
The project will upgrade the traffic signal system, and other components at major north-south and east-west corridors to improve the traffic operations and mobility in the City. These improvements will be planned and developed in conjunction with adjacent cities to ensure that traffic operations are coordinated through major corridors within the SR-710 area.
