Future transbay tube fantasy planning

February 4th, 2019

Recently there’s been talk of building a second rail tube under the San Francisco Bay. This new tube would be larger than the existing transbay tube and serve two major purposes:

  1. BART could offer limited 24 hour service while still having a maintenance window if one of the tubes had to be closed
  2. Future expansion possibilities for CalTrain, high speed rail, and perhaps even Amtrak

If we put aside the question of when to build this second crossing the next question is where? There’s no pressing reason to build a second tube next to the existing BART tube between Embarcadero Station and West Oakland.

BART has previously expressed concern about a tube to Treasure Island due to soil stability issues so I won’t include that as an option (even though I personally like the idea.)

Here are the fantasy transbay tube plans I’ve come up with. All maps images are courtesy of Google.
 

Alameda connections

The distance between San Francisco and Alameda (the island, not the county) is short enough that a tube could be practical. Today Alameda isn’t well served by transit so this route may help bring visitors to Alameda’s breweries and boat adventures.

On the Oakland side BART could connect to the existing Lake Merritt Station, ideally stopping along the way at a new Jack London Square Station. There’s also an obvious place to connect to Amtrak as well.
 

Geary Street

Let’s start with the obvious: BART intended to build a subway under Geary Street since day one, but somehow never got around to it. It’s easy to see the appeal: Geary is close to the Legion of Honor, Japantown, the Presidio, and could potentially go all the way out to the beach and the Cliff House. It’s also a major shopping district with restaurants, bakeries, bookstores, etc.

On the eastern side this subway could connect to the existing Market Street BART subway before meeting at the Transbay Transit Center and exiting San Francisco through a tube to Alameda.

The biggest problem with BART adding a Geary Street subway at this point is how it would get there: Muni Metro’s's upcoming Union Square station is quite deep, probably too deep to tunnel under. Digging under the Financial District seems equally troublesome. If only San Francisco had some kind of “subway master plan”
 

Mission Bay

Connecting somewhere near Mission Bay, BART could build a new line to major event spaces like AT&T/Oracle Park, the new Warriors stadium, etc. It comes close enough to the CalTrain line to provide an opportunity for future expansion, and would serve as a connection to Muni’s upcoming Central Subway line near the south portal.

On the San Francisco side BART would have a few places to connect to its existing subway, though all of them would be expensive. The longest route would be to tunnel all the way to Cesar Chavez, the shortest would be to go under 16th Street.

The pros of this plan seem pretty clear: connecting BART to one of San Francisco’s biggest new neighborhoods is a no brainer. The cons? There’s no direct connection to BART’s busy Market St. tunnel or the Transbay Transit Center.
 

 

North Bay connections

It’s unclear BART will ever go to the North Bay, but this was part of the original plan and I have a few ideas. Just getting BART to connect with the new SMART trains in the North Bay would be a major achievement and is worth considering for that reason alone.

For better or worse these plans involve skipping the East Bay entirely and focus on the North Bay via San Francisco. Connections from the North Bay directly to the East Bay are out of scope for now, negating the ability for BART to operate 24 hours — but it’s still worth thinking about. These are fantasy plans after all.
 

Golden Gate Tube

Okay, let’s return to the Geary Street subway. Originally BART planned for the Geary line to go over the Golden Gate Bridge on the lower deck. Unfortunately this wouldn’t be feasible today without major changes to the bridge. Building a second Golden Gate Bridge presumably wouldn’t be very popular, so why not go underground?

The subway tunnel would head west under Geary, take a sharp turn somewhere near the Presidio, then go underneath the Golden Gate before connecting somewhere on the North Bay side. Clearly there’d be a BART stop in the Presidio, if not two.

How this would connect to the Transbay Transit Center is a whole other can of worms but it does provide a potential shared crossing, assuming some minor hand-waving about the details of the Transbay Transit Center connection.

 

Island tubes to Tiburon

I’ve saved my favorite for last, a costly plan best described as “a series of tubes.” Specifically three of them.

What if BART built a subway tunnel from Market Street to Columbus Avenue in North Beach to a tube system connecting via islands to the North Bay? This would hit many key areas including the Financial District, North Beach, and Fisherman’s Wharf. Tubes would be built to connect Alcatraz, Angel Island, and Tiburon.

Connecting this huge tunnel system to the Transbay Transit Center could be reasonable depending on the route configuration. While some North Bay locals would benefit from this plan, it could also be a huge benefit for tourism. Imagine coming to San Francisco on vacation and taking a train to not only Alcatraz but also into wine country. Obviously the ferry companies would strongly disagree with me here.
 

Those are my proposals. Will any of these ideas ever come to fruition? If so hopefully I’ll be remembered as a modern day Emperor Norton.

Salesforce Transit Center, opening day

August 12th, 2018

Salesforce Transit Center, Opening Day
 

After years of construction it seemed like the new Transbay Salesforce Transit Terminal Center would never open; and yet today, it finally did… sort of. It’s clearly unfinished, and construction workers were still there today (a Saturday) working on the gondola. The underground train platforms weren’t open, and no physical work has been done to even build the tunnel to the station.

So perhaps it’s best to think of this as opening day, with a few major caveats. For now only a few local transit agencies serve Salesforce Transit Center via bus, with bus operations to and from the East Bay to start tomorrow. Permanent restaurant and retail space is also still also on the to do list.

But enough about the future for the moment; let’s start with what’s there now.

The building itself is hard to miss; it’s a wavy undulating mesh hovering over several streets, with trees popping out from above. Heading in just past Salesforce Tower is an enormous lobby, with monolithic signs everywhere pointing to different transit agencies. Filled with natural light, the lobby is bright, clean, and frankly looks like a transit station. Not all the displays showing departure times were hooked up yet.

I kind of expected just to walk in and check the place out, but little did I know many others had the same idea. Turns out I’m not the only one who likes to see new things. Despite getting there early I had to wait in a long line for the escalator. SFPD acted as crowd control, only letting groups up at a time.

It seems the crowds weren’t expected; the lines leading up to the escalators and elevators were ad-hoc, taking up so much space that a group of dancers gave up on dancing and began posing for photos instead.

When I finally got on the escalator I looked straight up and saw a skylight… with shadows of people standing on it. Normally standing on a skylight is a bad idea, but this one is intended to act as a floor.

The main escalator skips the second floor, heading straight to the bus stops on the third floor. Here you’ll be able to take a bus to the East Bay and beyond. For opening day it was a sort of museum exhibit with presentations from local transit agencies.

AC Transit showed off their new double decker bus. Various transit agencies had well-preserved antique buses on display. Someone had brought in an old car from Hupmobile, a semi-obscure defunct car manufacturer. I confess I thought it was a Ford Model T at first glance.

I was a little thirsty after waiting so long to get up to there. The vending machines were largely not operational yet. Fortunately SFMTA had a table with free Hetch Hetchy water and cups to match.

The real star of the show on the third level is the suspension bridge. This is a bus-only bridge over Howard Street that can be easily spotted from Second and Howard. They were letting people walk onto the base of the bridge to get a peek at it, but no further.

It’s too bad they didn’t incorporate a sidewalk with space for people to take photos, I could imagine this funny little bridge being a popular selfie spot for travelers.

The entire third level was open to let people walk around. Normally you won’t be able to get up close to the metal lattice “skin” of the building on the bus level, but for opening day there was no risk of getting run over by a Greyhound.

I’ve watched the lattice go up in sections for what felt like ages, so it was neat to finally get a peek outside from within.

Obviously people hadn’t flocked here to see a bunch of buses. The real draw was to see Salesforce Park, the city’s first elevated park.

Despite crowd controls this was wall-to-wall people, gawking at the scenery. It’s a bit of a head trip — you look one way and there’s a green park with trees and grass, you look the other way and it’s office towers and skyscrapers. Unless you look over the ledge there’s not much visual indication that you’re above ground at all. This dissonance may grow with the trees and shrubs themselves.

Plaques throughout the park explain what you’re looking at — a fountain (it was off), seismic joints in the building, plants in the garden, etc. There’s a playground for kids, a couple of plazas, and a few grassy areas for lunches and picnics.

The park connects directly to both Salesforce Tower and 181 Fremont. The sky lobby for Salesforce Tower hasn’t been completed yet; I could see construction workers and unpainted drywall behind glass windows.

I’ve heard this park was inspired by New York City’s High Line Park, but I’ve yet to visit NYC so I’m not able to make any comparisons.

For opening day there were a few vendors in one plaza, selling food, coffee, beer, and oddly enough cookie dough. Stands with free to borrow books and board games were available as well. There were a few tables to sit at, though not nearly enough to meet demand. When the novelty wears off I could see this park as a place for nearby workers to take a lunch break.

Bands and DJs played at two stages in the park. Due to all the buildings around it, some parts of the park were shady whereas others were sunny on an unusually warm San Francisco afternoon.

One big question that kept lingering in my mind was how this new station would outlast the one it replaced. Although the old Transbay Terminal was once touted as the “Grand Central Station of the West,” by the time I was around to see it the place was kind of a mess. The “terminal” aspect of it largely referred to the trains that once arrived at the station coming over the Bay Bridge. The building’s restaurant and bar had closed ages ago, and the waiting area was essentially used as a homeless shelter.

Until train tunnels are built — this time from the Peninsula side, and eventually perhaps a second Transbay Tube — it’s hard to see how the Salesforce Transit Center will be much more than a fancy elevated park. The bus level is nice and all, but you don’t need much space for a bus stop. It’s also worth pointing out that the new low-cost bus operators like Megabus and Flixbus haven’t announced plans to stop at the Transit Center.

Perhaps the most odd omission is the lack of connection between the Transit Center and Montgomery Station. It’s a very short walk, hopefully some signs will appear soon directing travelers between the two. Should be easy enough to fix.

If the new Transit Center has one thing going for it, it’s the neighborhood. Between when the original Transbay Terminal was built and today, the surrounding area has grown tremendously. Factories and shipping businesses were replaced by offices filled with knowledge workers. Moscone Center opened, expanded — and is being expanded again, right now. New hotels sprung up, new subways, a new baseball stadium… the list goes on. This version of the Transit Center seems more likely to succeed; at least if its underground train platforms ever see service, that is.

Of course, all of this will have been for nothing if the Millennium Tower — currently sinking and leaning towards Salesforce Tower — comes crashing down.

Perhaps that should be addressed before the next earthquake, let alone before any new tunnels are built in the area.

By the time I made my way back to the escalators to leave, the crowds had grown immensely — I was glad I’d arrived early. It also seemed unintuitive to me that so many folks wanted to check out the new Transit Center when the city was also hosting Outside Lands, the Filipino Parade, and a Giants game all on the same day.

With all of those activities going on, who knew the opening of a new Transit Center and park would attract such a large crowd? Not me, that’s for certain.

Muni needs signal priority

March 16th, 2011

The SFMTA recently announced some big changes to the messy intersection at Church and Duboce, which is a notorious mess for Muni Metro, the 22 line, bicycles, private vehicles, and pedestrians. Streetsblog covered the changes in depth in an excellent article.

One strange aspect to the renovation which Streetsblog mentions is that there will still be no traffic signals at the intersection.

SFMTA staffers said adding traffic signals would cause unnecessary delays to Muni lines, particularly for the 22-Fillmore running north on Church Street, Kaufman said.

Traffic lights = delays? Somehow that statement doesn’t ring true.

Anyone who regularly travels on Muni Metro through this intersection, or the similar intersection at Ulloa and West Portal, can testify that these intersections are a major source of Muni Metro delays. (The West Portal intersection is actually worse, since Muni Metro has a signal but other traffic does not.)

If we really want to be a “transit-first” city, doesn’t it make sense to have traffic signals that give preference to transit? Especially in the case of Muni Metro, which is supposed to be “rapid” but when mixed with traffic is anything but.

Other transit systems give signal priority to trains and buses. Even VTA in Santa Clara County — which admittedly is a lousy system for many other reasons — gives signal priority to express buses.

Since Muni Metro in many cases has special traffic signals which do not apply to cars, couldn’t we at the very least use these signals to allow Metro LRVs to pass through intersections with priority to all other traffic?

Signal priorities could give many other Metro lines an advantage on many lines, including:

  • T line on 3rd St
  • Both the T and N lines on King and Embarcadero
  • M and K lines along West Portal
  • M line on 19th Ave
  • N line at 9th and Irving
  • J line on Church
  • Granted, this is an expensive proposition, as it involves altering traffic signals, adding signal remotes to trains, and operator education. But when it comes to making getting around the city with reliable speed, it’s worth the cost.
