An Old Plan to Build a New Tunnel Under Bernal Heights

Along time ago, in the office of a city planner far, far away, a plan was hatched to solve San Francisco’s traffic problem.

The year was 1928, and the San Francisco Traffic Survey Committee had mapped out a vision for the future that involved widening selected city streets to adapt them for use as major arterial throughfares.

Bryant Street in the Mission was to become one such proposed artery; it would carry much of the traffic traveling between South of Market and the Peninsula via Bayshore and San Bruno Avenues. But how would all those vehicles get from Bryant to Bayshore (and vice-versa)?

Why, through the Bernal Tunnel, of course!!

Look closely, and it’s right there: A short tunnel running under present-day Franconia Street to whisk motorists through layer upon layer of our beloved Bernal Hill chert. One end of the tunnel would open roughly at the intersection of Holladay and Faith, and the other would disgorge traffic at the site of what is now that weird triangle-shaped gas station at the junction of Precita, Bryant, and Cesar Chavez.

Notice the other plans in store too. Like, for example, completing the street grid across the top of Bernal Hill via a much straightened-out Esmerelda Avenue (presumably after much of the hilltop was quarried and flattened). GENIUS! No Bernal Hill Park! No unseemly wildlife! No feral radish! Just a few dozen more homes, and a much more tidy drive around the neighborhood… all in the name of Progress.

  1. I don’t think that Esmerelda was actually part of the plan — that was just the Department of Public Works base map that they were drawing on top of. It was one of the “paper streets” that were part of the original subdivision but were never built. DPW maps in the 1940s started distinguishing between streets that actually existed and those that were just on paper, but by then Bernal Heights Boulevard had been built too.

  2. Here seems like as good a place as any to try out this new urban planning idea: bike escalators! Listen, this is going to be great. It will be like the grocery cart escalator in Bed Bath and Beyond, only outdoors. I’m thinking it can shoot right up Alabama. You can also affix your baby stroller to it. So convenient and efficient! So Jetsons! Ski lifts could work, too.

  3. Also interesting things of note in the plans:

    1. The proposed Broadway Tunnel in the plans was actually completed in 1952.
    2. The Bay Bridge was proposed to head straight east in SOMA instead of north-east as it eventually went.
    3. The Branch County Jail at Balboa Park is now CCSF. Draw your own conclusions. Just kidding.
    4. There is a place south of Silver Avenue called “Lick Old Ladies Home”. Hmm.

  4. Does anyone have information on the remnants of a tunnel at Bayshore and what would be Costa or Faith if it went under the freeway?
    Kinda to the left as you end your decent from the pedestrian freeway overpass. It’s bricked and cemented up, and begging for an unbricking and exploration. ( Or not.)
