Thursday: Dumbarton corridor study comes to Menlo Park


How can transportation between the East Bay and the Midpeninsula be improved?

A study of the Dumbarton corridor – including the current vehicle bridge (State Route 84) and the abandoned Dumbarton rail bridge – is underway in an attempt to answer that question.

The roughly $1 million study, funded by Facebook, will analyze the feasibility of currently undefined options to reduce congestion in crossing the bay.

A community meeting for people on the Peninsula to offer their suggestions, comments and concerns will be held Thursday, May 12, from 7 to 8 p.m. at the Menlo Park Senior Center in the ballroom at 100 Terminal Avenue in Menlo Park. A similar meeting was held in the East Bay on May 10 in Fremont.

The study's purpose is not to approve any future projects, but instead explore how feasible different options could be to address congestion, and to look into what could be done with the currently defunct Dumbarton rail bridge, according to the SamTrans website. The study will look at car, transit, bike and pedestrian modes of transportation. It will also analyze the broader street networks and transit lines that connect Peninsula cities like Redwood City, Menlo Park and East Palo Alto to East Bay cities like Newark, Union City and Fremont, SamTrans spokeswoman Tasha Bartholomew.

Currently, the Dumbarton Express, a bus administered by the Alameda-Contra Costa Transit District on the East Bay, is the sole public transportation option to cross the bridge. Go to for more information or to register for the free meeting.

To submit a comment, attend either of the meetings, email, call 650-508-6283, or send by mail to the following address: Attention Melissa Reggiardo, San Mateo County Transit District, P.O. Box 3006, 1250 San Carlos Avenue, San Carlos, CA 94070.

There already is a bike lane across the Dumbarton Bridge. It would be real nice if a bike path could connect this to Palo Alto through the baylands, instead of forcing bicyclists to ride down University Ave to get to Palo Alto. I thought Facebook promised to build this bike path (when they first moved into their current campus), but nothing ever happened.

Using the Dumbarton rail line to alleviate the East-West lower peninsula commute sounds like a great idea. The bridge and rail rights of way already exist. They would just need to be rehabilitated, which won't be cheap, but neither will be other methods to expand cross bay traffic capacity. This has the environmental benefit of getting more people out of their cars.

Actually, with respect to the Bayfront trail, something did happen; there was a bike trail built on the east side of University Avenue, starting at highway 84 ... the thing is it doesn't go all of the way quite yet. At a Facebook meeting at East Palo Alto town hall a couple weeks ago, I asked about it ... a woman in charge of bike trail development said the next portion, that would complete a connection it to Cooley Landing, needs to go through environmental review, which is can take awhile ...

She said things were moving forward for a bike trail that parallels the Dumbarton Rail Line towards Redwood City (not across the Bay)... they have a proposed bike bridge that would run parallel to the existing unused Dumbarton corridor rail bridge that crosses 101. (The parallel bicycle bridge would leave the existing bridge available for trains or whatever.) She said she was hoping for bridge completion in 2018, but merely getting approval by 2018 was more likely. There's also plans for a pedestrian bridge halfway between where Willow Road and Chilco Road meet Bayfront expressway.

In other news in that vicinity, massive salt pond restoration along Bayfront Expressway may begin as soon as next month: Web Link
