History 

SR-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).

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, requires 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 opposed this bill due to the absence of Monterey Park's representation on the Terminus Regional Planning Task Force and requested a seat on the proposed task force.

CIP 96026- Adaptive Traffic/Traffic Responsive Control System

Start Date: Spring 2025End Date: Winter 2026
Project Manager: Ziad MazboudiStatus: In DesignProject 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 Winter 2026. Construction is expected to begin Spring of 2025.

The City of Monterey Park's Vision Zero (VZ) Action Plan serves as the foundation for building a safer, more connected, and more inclusive transportation network. Through a series of coordinated planning efforts, including a Safe Routes to School Plan, Active Transportation Plan, and Complete Streets Plan, the City is working to improve how people move through their neighborhoods, access local destinations, and experience public spaces. These plans reflect a shared commitment to safety, sustainability, and equity, and they are shaped by input from residents, families, and community partners.

The City was awarded $984,000 funding through the FY 2022 Safe Streets 4 All (“SS4A”) Federal grant and has entered into a pass-through agreement with the Los Angeles County Metropolitan Transportation Authority (“LACMTA”), Agreement No. 9200000000SS4A04 on 12/7/2023 and FIS No. 700512. The City Council adopted Resolution No. 2022-R75, adopting a Vision Zero Policy, a Citywide guiding principle for transportation planning, the design of streets and sidewalks and the maintenance of the public right of way, and to prioritize the development of safe roadways and the highest level of safety for all road users through new policies, systems and infrastructure improvements for pedestrian, bicyclists and motorists.  

On October 15, 2025 the City awarded a Professional Services agreement to Kimley-Horn and Associates for the preparation of Vision Zero Action Plan in the amount of $957,140 for the project.
