Summit Platinum Sponsor Spotlight: Parsons
Parsons Continues to Provide Critical Rail Services for Southern California
Parsons Corporation is continuing their collaboration with the Foothill Gold Line Construction Authority to complete phase 2B2 of the Foothill Gold Line project. Parsons will provide design and construction support for the next segment of the longest linear light rail line in the world. Through this phase, Parsons will design a 2.3-mile extension from Pomona to Claremont for the Metro A Line light rail system.
By extending the A Line, light rail options will increase and open access to neighborhoods that were once limited for commuters. Parsons’ design will improve and ease commuter and visitor access between downtown Los Angeles and the eastern portion of Los Angeles County, through inexpensive transportation.
This segment, along with previous design phases, will provide innovative and sustainable solutions that reduce traffic congestion, improve air quality, and help commuters reach their destinations safely and reliably. Parsons’ rail and transit experts have helped improve connections between California communities since their founding in 1944, including celebrating the substantial completion of the most recently completed phase of the Foothill project from Glendora to Pomona in 2025.

The SCAG Regional Resilience Toolkit shares resources and information to support Southern California communities, cities, and counties with resilience planning. The toolkit is intended for use by any jurisdiction in Southern California, regardless of size, population, experience in resilience planning, or direct encounters with the shocks and stressors of the current age.
The “Water Resolution White Paper” evaluates shared water management challenges and identifies opportunities for stronger coordination, investment, and technical support across jurisdictions.

OCTA, Working in Partnership with Caltrans, Makes Significant Progress on SR-91 Improvements One Year Later
A year after breaking ground on the SR-91 Improvement Project, significant progress is being made on construction along one of Orange County’s busiest freeways for people traveling to and through Anaheim, Fullerton, Orange, Placentia and Yorba Linda.
The $779 million project, led by the Orange County Transportation Authority in partnership with Caltrans, is funded by OCTA’s Measure M half-cent sales tax program, reinvested toll revenue from those who use the 91 Express Lanes, and state and federal funds.
The project is broken up into three construction segments stretching approximately between SR-57 and SR-55. In the segment at the SR-91/Lakeview Avenue interchange, crews recently put into place a new traffic configuration that helps enhance safety, reduce merging conflicts and improve access between SR-91 and SR-55.
New Westbound SR-91 On-Ramp at Lakeview Avenue
As of early March, the existing westbound SR-91 loop on-ramp at Lakeview Avenue was permanently closed. Now, drivers traveling northbound and southbound on Lakeview Avenue use a new temporary signalized intersection to access the westbound SR-91 straight on-ramp. Northbound drivers will turn left at the signal to access the on-ramp, while southbound drivers will turn right at the signal.
In addition, the eastern side of the Lakeview Avenue bridge will be closed to pedestrians through August 2026. The western sidewalk remains open.
Overall, The SR-91 Improvement Project is enhancing 6.6 miles of SR-91 through Anaheim, Fullerton, Orange, Placentia and Yorba Linda. Up to 321,000 vehicles travel this stretch daily, and that number is expected to grow.
The project, which broke ground in early March 2025, is designed to reduce congestion and improve travel times, improve freeway interchange connections, and reduce weaving and merging.
The project will also reconstruct key overcrossings with enhanced safety features and amenities for pedestrians and cyclists. The improvements are expected to be completed by 2030.
