Bollinger Canyon Road Overcrossing Project Also Wins League of California Cities Award

The Bollinger Canyon Road Bicycle and Pedestrian Overcrossing Project also received the 2026 Outstanding Local Streets and Roads Project Award from the California State Association of Counties (CSAC), League of California Cities (Cal Cities), and County Engineers Association of California (CEAC). It is the highest award presented annually at the California League of Cities Public Works Officers Institute Spring Conference.

“Counties and cities across California lead in delivering sustainable and enduring transportation projects,” said Johannes Hoevertsz, President of CEAC and Sonoma County Public Infrastructure Director. “By applying innovative approaches, local governments are strengthening mobility while protecting the long-term performance of their streets and roads.”

This year’s overall winner, the City of San Ramon, is recognized for its Iron Horse Trail Bicycle and Pedestrian Overcrossing at Bollinger Canyon Road, a transformative project that enhances safety and access for pedestrians and cyclists.

Overall Winner:
Iron Horse Trail Bicycle and Pedestrian Overcrossing at Bollinger Canyon Road, City of San Ramon

The $29M Iron Horse Trail Bicycle and Pedestrian Overcrossing at Bollinger Canyon Road is a 340-foot, cable-stayed bridge that provides a safe, grade-separated crossing over one of San Ramon’s busiest corridors.  Anchored by 900 feet of MSE wall approaches, it eliminates a previously signaled crossing and completes a link in the 30-mile regional Iron Horse Trail system. The project integrated context-sensitive landscaping with over 7,000 native and drought-tolerant plants and 80 trees along with community gathering spaces enhanced by architectural lighting.

“This project represents years of thoughtful planning and hard work from our Engineering team to improve safety and accessibility across one of the city’s busiest roadways,” a Facebook post on Thursday, March 12th reads. “Congratulations to our Engineering team for their dedication and hard work in bringing this important project to life!”

The overcrossing officially opened to the public on Saturday, July 19, 2025.

ACEC California Awards

The Contra Costa Transportation Authority and City of San Ramon received an Honor Award from ACEC California, one of eight in the San Francisco Region, for the Iron Horse Trail Overcrossing at Bollinger Canyon Road. The project was submitted by the Oakland office of COWI North America, Inc., of the ACEC California Bay Bridge Chapter.

According to ACEC California, COWI was contracted by the Contra Costa Transportation Authority for the overcrossing project — a striking new pedestrian and cyclist bridge that provides a safe crossing across the busiest arterial corridor in the city and uninterrupted connectivity along the Iron Horse Trail. The City of San Ramon is the owner.

As Prime Consultant and Engineer of Record, COWI led the design, engineering, and design support during construction for the $21.6 million project. The result is a 340-foot, six-span cable-stayed bridge with 570 feet of retaining wall approaches, a central V-shaped steel pylon, and architecturally integrated lighting and railing systems.

The overcrossing enhances safety and connectivity for tens of thousands of San Ramon residents and trail users along the region’s most popular trail. While the project utilized its full budget, COWI’s innovative design and accelerated construction strategies generated substantial indirect savings by minimizing traffic disruption, shortening construction duration, and reducing environmental and community impacts.

“This bridge is a celebration of safe, sustainable design and community placemaking,” said Matt Baughman, Associate Project Director at COWI. “From concept to completion, COWI’s team worked closely with our client and stakeholders to deliver a truly iconic project.”

There were two other local ACEC California winners including the City of Antioch which received a Merit Award for its Brackish Water Desalination Plant, submitted for consideration by Carollo Engineers’ Walnut Creek office of the East Bay Chapter. The plant was inaugurated on September 15, 2025. According to the City of Antioch, this facility strengthens Antioch’s water supply by using a combination of existing and new infrastructure to increase reliability and provide greater operational flexibility. This facility is a landmark investment in the City’s future, ensuring a more resilient water supply for the community.

The City of Martinez received a Commendation Award from ACEC California for the Alhambra Avenue Downtown Improvements, submitted by LCC Engineering & Surveying, Inc. of Martinez, also of the ACEC California East Bay Chapter.

According to LCC, the company was hired by the City of Martinez in Winter of 2022 to provide land survey and civil design services for this Complete Street Improvement Project which included one mile of mill and fills, base-failure repairs, crack-sealing and micro-surfacing, re-striping to include Class 2 buffered bike lanes, new ADA compliant curb ramps and crosswalks.  The project was a federally funded project which triggered extensive environmental studies due to the proximity to significant historical buildings.  LCC teamed with HDR for the extensive environmental studies required.  However, LCC performed all of the right of way and utility coordination to obtain the Right of Way Certification for the Project. Construction was completed in spring 2025.

LCC has provided civil engineering and land surveying services to the City of Martinez since the firm was established in 1954.

The ACEC California’s annual Engineering Excellence Awards competition recognizes outstanding achievements in engineering and land surveying projects completed by California firms. Entries are accepted into one of 12 project categories: studies, research and consulting engineering services; building/technology systems; structural systems; surveying and mapping technology; environmental; waste and storm water; water resources; transportation; special projects; small projects; energy; and industrial and manufacturing processes and facilities.

Projects were recognized for demonstrating an exceptional degree of innovation, complexity, achievement, and value. Twenty projects earned the prestigious Honor Award distinction, twenty-seven were recognized with Merit Awards, and fifteen Commendation Awards were granted.

“We are proud to recognize these ACEC California firms for delivering an exceptional degree of value and technical excellence to our communities,” said Tyler Munzing, Executive Director of ACEC California. “Quality infrastructure—from dependable drinking water to safe, efficient roadways and structurally sound public spaces—is essential to our state’s success. These award-winning projects showcase how our engineering and land surveying firms are passionately building a more resilient and connected California.”

The awards were announced at the Engineering Excellence Awards Banquet at the Disneyland Hotel on February 19, 2026. Themed “Dream Builders: Engineering the Magic of Tomorrow”, the conference highlighted how engineers and land surveyors can influence the future through innovation, imagination and impact. The annual celebration was also a fundraiser for the ACEC California Scholarship Foundation 501(c)3, which provides scholarship awards to graduate and undergraduate students who are recognized for their notable and outstanding academic achievements.
