NOTICE OF CONSTRUCTION – San Bruno Canal Bridge Closure


South Airport Blvd & North Access Rd San Bruno Canal Bridge Replacement Project

(City Project No. ST1301)

04-SM-0-SSF /  BRLS-5177(030) / 0413000001L-N



Dear Property Owner I Proprietor I Tenant/ Resident:

Please be advised that the San Bruno Canal bridge at South Airport Boulevard will be closed effective May 21, 2018 due to rapidly deteriorating condition of the piles supporting the bridge. Construction to replace the bridge is scheduled to begin immediately and the new bridge opening to traffic is expected by the end of 2018.

Public safety is the City’s number one priority. Traffic detours will be implemented to facilitate safe travel around the construction site. The city recognizes the inconvenience to the public and will minimize disruption as much as possible. Thank you in advance for your cooperation.  Additional project information including a project description and project location map is given on page two.

Please log into City web-site at for updates.


The South Airport Boulevard Bridge over the San Bruno Canal at North Access Road and the 380 Freeway on ramp needs to be replaced due to its deteriorated condition. The initial bridge was built in 1949 on wooden piles. In 1975, the bridge was widened, and the new sections were supported on concrete piles. The City with the assistance of Caltrans has been successful in obtaining funding from the Federal Highway Administration (FHWA) for the design and construction.


The City conducted an inspection recently and determined that the pile column foundation (both wooden and concrete) exhibits advanced excessive deterioration. An ensuing bridge structural assessment concluded that the bridge is susceptible to failure under currently permitted vehicular loading. To protect the travelling public and construction workers who would be performing work beneath the bridge, the City will be closing the bridge immediately effective May 21, 2018, prior to performing the bridge replacement project instead of maintaining traffic over the bridge during construction.

The bridge is scheduled to be closed effective May 21, 2018 and remain closed until the bridge replacement construction is completed at the end of 2018. The public is requested to follow the detour signs to navigate through alternative routes once the bridge is closed.




Construction Start: May 2018

Anticipated Completion: December 2018

    That’s gonna be a zoo and a half. Traffic going towards Costco from 380 is going to have to be rerouted and the traffic from South Airport heading towards 380 and towards the airport is also going to have to be rerouted. Good luck as there just aren’t many alternatives.

    I know that spot EXTREMELY well and the part of North Access Road that goes past Park SFO and the little Shell Aviation Products building is going to be heavily impacted. It will be very interesting to see how they handle it.

    Classy response Laura. I said it was going to be bad five days ago and it’s worse than I imagined. I got gas at the ghost town known as Costco. NO LINES. No waiting. No customers.

    Going north on South Airport, I opted to go 101 North and got off at Oyster Point instead of staying on S. Airport and turning left past Dunkin’ Donuts. Absolutely horrible mess.

      How do you get to SFO costco either from 101 or 280? I am totally confused from the detour signs and ended back to the freeway.

      Hi LL,
      We put your question our on our FB page to see what others would recommend and below are a few of the more helpful responses which may benefit you.
      Thank you.

      Masara Al Sayegh: You can take 280 and take the bridge instead of going underneath it, you then take the first exit after the bridge to the right. So like other words, instead of taking the left exit where the detour is, keep right take the bridge and take the first exit on your right, you will turn right then straight Costco will be on your left. I work there and I felt it’s kinda hard to explain, hope I helped

      Brian Barry: So getting there is easy. Just grabbed gas at 4 today. That place is a ghost town because the signs scare everyone. Getting out at 4 today was awful. Went there last Saturday. In and out was super easy. Everyone is avoiding the store. I’d say go for it at “peak” times on weekends. I used South Airport both ways.

      Rose Chang Chiu: We normally take North Access Road, but we went on 101 North instead, exited South Airport, and turned right
      Those detour signs are misleading… goes right to the freeway, but I guess they figure most people are headed to the freeway, not Costco

    Totally Lame-they should have put in a temporary bridge before doing this-Even if restricted to just cars and not heavy trucks-looking at the aerial view shows this is clearly possible, and such things exist and can be secured.

    Wow. What a mess. Made the mistake of going to get gas yesterday. 90 minutes later I finally made it home. Won’t be going over there until that’s done.

      There is no place to put in a temporary bridge and it would be very expensive to do so. The problem is there really isn’t any adequate solution other than to close the structure. It sucks, but I don’t believe an alternative exists.

    Brilliant! Why did the City not think to do this before and how are they going to address the problems going forward? The city did not consider the impact on the employers and their employees on the East Side of South San Francisco.

      I meant to say Brilliant idea Roger! A temporary bridge would really help the situation.

      I don’t see how some of those businesses over there are going to survive. I feel multiple lawsuits coming. The impact on Costco, for instance, has to be huge.

    It’s horrible. I work here 2-3 days a week and its made a relaxing commute from my nearby home into a nightmare. I’m local so I know all of the back roads, but getting in or out except for the middle of the day is pretty bad. It’s a congested area period. I feel bad for the local business’ as well. When getting to a business becomes difficult, people just stop coming. Fine if you can visit middle of the day, but not for those of us who have to come in and leave during crush hour.

    The city council showed restrained outrage at the city manager and public works dept. but I didn’t hear an apology to the community, just Leslie giving the canned response on another thread here at ESC.

    They highly paid cm needs supervision, but there is no leadership to provide it. We are up a creek, without a paddle.

    LL, actually it is very easy. Just go to the South Airport Blvd exit on 101 North. Make a right at the light and Costco is a half mile away on your left.

    There are NO lines for gas as the Costco has become a ghost town.
