History
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).
The Future of the 710 Project
There are no plans to makes changes to the portion of the I-710 that runs through Monterey Park.
However, four road locations have been identified in the City of Alhambra for improvements projects: Conversion of the I-710 stub from a six-lane freeway into a four-lane arterial street between the I-10/I-710 interchange and Valley Boulevard, as well as upgrades at three key Alhambra I-10 interchanges – Fremont, Atlantic and Garfield. Additional information on the City of Alhambra's process and a survey which is open to all interested parties can be found at AdvancingAlhambra.org.
California Senate Bill 710
SB 710, authored by California Senator Maria Elena Durazo, would require the Department of Transportation to establish and administer a Terminus Regional Planning Task Force to meet quarterly and submit a report to the Legislature on the issues of traffic and potential land use related to the State Route 710 Terminus adjacent areas.
The Monterey Park City Council opposes this bill due to the absence of Monterey Park's representation on the Terminus Regional Planning Task Force and has requested a seat on the proposed task force.
Project Updates
CIP 96047- Monterey Pass Road Improvements | Start Date: Summer 2023 | End Date: Winter 2026 |
| Project Manager: Ziad Mazboudi | Status: In Design | Project Location(map) |
The proposed improvements include traffic signal system improvements and upgrades to provide efficient and reliable synchronization to improve traffic flow; improved bus stops and installation of separated bike lanes with parking & painted buffers; the traffic flow related/impacted improvements will impact portions of existing sidewalks, pavement/new-pavement overlay, signing/striping and other misc. improvements/areas.

CIP 96023- Garfield Avenue Capacity Improvement | Start Date: | End Date: |
| Project Manager: Ziad Mazboudi | Status: In Design | Project 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 | Start Date: | End Date: |
| Project Manager: Ziad Mazboudi | Status: In Design | Project 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 | Start Date: | End Date: |
| Project Manager: Ziad Mazboudi | Status: In Design | Project 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 |
Start Date: |
End Date: |
| Project Manager: Ziad Mazboudi | Status: In Design | Project Location(map) |
The City of Monterey Park and ADVANTEC Consulting Engineers, Inc. (ADVANTEC) have embarked on a major effort to develop and implement corridor mobility improvement projects (MIPs) on three local arterials—Garvey Avenue, Atlantic Boulevard, and Garfield Avenue (35 intersections). The purpose and objective of this project is to upgrade the traffic signal system, and other components at the major north-south and east-west corridors to improve the traffic operations, mobility, safety, and the quality of life in the City of Monterey Park.These improvements will be planned and developed in conjunction with adjacent cities and Los Angeles County (LA County) to ensure that traffic operations are coordinated through major corridors within the SR-710 area. In addition, LA County Department of Public Works (LACDPW) will be an active participant in this project to coordinate the City’s overall traffic management system development and integration to the Countywide Information Exchange Network (IEN), a coordinated network engineered to share traffic signal control information between agencies. Coordination with LACDPW will maximize the regional arterials corridor traffic operational performance and minimize any potential conflicts. The project will be conducted in two phases: - Phase 1 consists of reviewing existing traffic signal system infrastructure conditions and preparing preliminary engineering documents for the implementation of recommended project improvements within the allocated funds from the grant.
- Phase 2 consists of a preparing project plans, specifications, and estimates (PS&E) based on the approved improvements determined during Phase 1. This phase also consists of procuring equipment, developing environmental documentation, bid and construction support, system integration support, and preparing a final project report including a "before and after study" comparison analysis.
The project will upgrade traffic signal, Intelligent Transportation Systems (ITS), and communications equipment along the project corridors. The project will also entails the preparation and implementation of new traffic signal timing and traffic signal synchronization and fine-tuning, installing a new central advanced traffic management system (ATMS) at City Hall, and implementing adaptive and/or responsive traffic control plans. Phase I of the project is anticipated to be completed in January 2024. Phase II design of the project is anticipated to be completed in May 2024. Construction is expected to begin Summer of 2024. For more information on the project including a map of the project, please click here. On August 2, 2023 the City awarded a Public Works Contract to Advantec Consulting Engineers, Inc., in the amount of $182,778 for Phase 1 of the project. |
