"Reduce and eliminate unsafe crossing maneuvers by pedestrians and bicyclists." That's how the City of San Ramon describes the point of a new bridge over Crow Canyon Road, the language pulled straight from its own project files. On September 21, the City Council voted 5-0 to fund the next step toward building it. If you use that stretch of trail to get your kids to school, walk the dog before work, or ride down to Central Park on a Saturday, here's the part that matters more than the vote itself: nothing about your crossing changes yet, and the numbers behind this approval suggest it won't for a while.

The council authorized a contract with the engineering firm Mark Thomas for up to $2,059,133 to design a bicycle and pedestrian overcrossing at Crow Canyon Road. Councilmember Sridhar Verose made the motion, Councilmember Richard Adler seconded it, and the vote passed without dissent. This is the second time San Ramon has taken this exact step. The first was the Bollinger Canyon Road overcrossing, which opened to the public on July 19, 2025, after a project that started with a concept plan in 2009.

What the Vote Actually Funds

A design contract is not a construction contract, and the difference is worth sitting with for a second. The $2,059,133 awarded to Mark Thomas covers engineering and design work only. It doesn't build anything.

The money itself comes from a federal earmark of $2 million, specifically directed at design, plus a $233,232 match from San Ramon's General Fund, bringing the total design budget to $2,233,232. Once the Mark Thomas contract is paid out, $174,099 remains in that budget. That's not much room for scope changes or delays before the city would need to go back for more funding, which tells you the design phase was budgeted precisely, not generously.

Construction is a separate ask entirely, and it hasn't been funded. The city's own Crow Canyon project page lists a tentative construction window of 2028 through 2030, explicitly dependent on future funding. That same page still carries an older line saying design was expected to begin in 2025, a holdover from before this contract existed. Municipal project pages don't always keep pace with council votes, which is a small but useful thing to know if you ever check one yourself.

The Same Corridor Plan, Two Different Clocks

Both bridges trace back to the same 2009 San Ramon Valley Bicycle Pedestrian Corridor Concept Plan. In 2013, the city brought on Biggs Cardosa Associates for engineering work that fed into a December 2015 conceptual design report covering both Bollinger Canyon and Crow Canyon. Up to that point, the two projects moved together.

Then they split. Bollinger Canyon's design was finalized and construction began in May 2023, a $29.1 million build (up from an earlier estimate near $21.8 million) that wrapped in a little over two years. Crow Canyon's design type wasn't picked until that same November and December of 2023, and getting from that decision to an actual signed engineering contract took until September 2026, three more years.

Sixteen years passed between the original concept plan and Bollinger's ribbon cutting. Crow Canyon is now seventeen years past that same starting point and has only just reached the point Bollinger reached years earlier: a signed engineering contract, with construction still ahead of it.

Why It Moves This Slowly

Neither project ran on a simple city budget line. Bollinger Canyon drew more than 82 percent of its funding from outside sources, including grants from the Bay Area Air Quality Management District, the Metropolitan Transportation Commission's Transportation for Livable Communities Program and One Bay Area, the Tri-Valley Transportation Commission, and Contra Costa Transportation Authority's Measure J. Crow Canyon's design money follows the same pattern, anchored by a federal Community Project Funding earmark rather than a straightforward city appropriation.

That structure explains the pace better than any single delay does. Grants get awarded on their own cycles, tied to their own application windows and eligibility rules, and a project has to line up multiple of them before it can move to the next phase. Crow Canyon has its design money now. Construction funding is a separate application, for a separate pot, on a timeline nobody has locked in yet.

What Changes On The Trail Right Now

For anyone using this stretch of the Iron Horse Trail today, the answer is nothing. The existing crossing at Crow Canyon Road stays exactly as it is: a dedicated, signalized crossing that doesn't line up with a cross street, built specifically for trail users rather than as part of a normal intersection. When the new bridge is eventually built, the city plans to remove that signal and crosswalk entirely and route trail traffic up and over instead. Until then, it's the same stop-and-wait experience it's always been.

San Ramon's section of the Iron Horse Trail runs 4.24 miles through the city as part of the larger East Bay Regional Park District trail connecting Pleasanton to Concord, and Central Park sits right along it with parking and restrooms if you're using it as a starting point. The Bollinger Canyon bridge already gave residents a preview of what a grade-separated crossing feels like a few miles up the same trail, no stopping, no signal, just a ride or walk straight over the road. Crow Canyon is meant to be the second half of that pair. It's just going to take longer to get there than the first one did.

If you're mapping out a regular route along this corridor, whether it's a school commute, a training ride, or a weekend loop through Central Park, worth checking back on the city's project page periodically rather than assuming a headline about a vote means shovels are close behind. Bay Homes Collective will keep an eye on the Crow Canyon timeline as it develops, the same way we track anything else that shapes daily life in the neighborhoods we work in.
