Work to Begin Friday on N-Judah Rail Replacement

After taking a beating from the never-ending flow of traffic on 19th Avenue and Sunset Boulevard for 30 years, the N-Judah’s track will be replaced where it intersects with those two streets starting Friday. For the next two weekends and the first weekend in December, crews will work to rip up the track and replace it with longer-lasting rail, at a total cost of $2 million. The work is part of the MTA’s $18 million Rail Improvement Project, which will also include sections of the J-Church and L-Taraval lines, drawing on local, state and federal funds.

Shuttle buses will replace service on the N-Judah west of Duboce and Church Streets for those three weekends. Muni bus lines 28 and 29 and automobile traffic will be diverted from
19th Avenue and Sunset Boulevard to side streets around the
construction zone for the three weekends of construction. "We appreciate
people’s patience as we do this work," said MTA spokesperson Judson True.

"During that time, we’re going to put in a new water line, any curb ramps that are needed, and also signal prioritization, which is underground," said MTA project manager Ha Nguyen. "Once that’s done, we’re going to repave the whole street. We’re going to replace the street, the base, and then redo the whole intersection with the asphalt concrete, and then re-stripe the street."

True said the work is necessary to provide reliable service. "The focus is often on our operating budget, and the challenges we have with our operating budget, but using capital dollars to invest in our rail, the overhead wire poles, all the other pieces of our infrastructure, is crucial to providing reliable service," said True.

The new rail will use a direct fixation method, which is sturdier than the current configuration, and should last longer, said Nguyen. Most of the N-Judah’s track is in better condition than it is at 19th Avenue and Sunset Boulevard, since the line has its own right-of-way and isn’t intersected by such high volumes of traffic elsewhere. Though the rest of the N-Judah’s rail in the Sunset is of the same age, the MTA doesn’t plan to replace it for at least another ten years.

"This is basically a state highway, 19th Avenue," Nguyen said today, standing at the intersection of 19th Avenue and Judah Street. "This is being crossed over with trucks, as we can see the heavy impact by traffic, it wears out much faster."

In addition to shortening some of the N-Judah track’s lifespan, 19th Avenue has complicated the replacement process, since it’s a state highway and is thus owned by Caltrans. The MTA coordinated with Caltrans for a year and a half in advance to prepare for the project, and had to obtain a permit from them to do the work.

Given the endless roar of traffic on 19th Avenue, it may be a good time for residents to enjoy a temporary reprieve from the highway at their front doors.

    This highlights the lie in your typical complaint motorists make about gas taxes and transit subsidy. Here is damage caused by users of a free road and the repair cost is being paid out of Muni’s capital budget. How much of that comes from gas tax? In a fair world it would be 100%.

  • The rail intersection that really needs help is at Portola, Sloat, and Junipero Serra where the K and M split off after coming out of West Portal.

    The K/M Split is getting a rail replacement next summer at a cost of $18 million for just that one intersection. Compare that to the $14 million to build out the entire bike plan. For 3 months next summer, the K and M rail lines will be discontinued and shuttle busses will run those routes.

    The Judah and Taraval rail replacements have already been delayed. The Taraval intersection was to be completed last summer. That delay means that traffic calming on 20th Avenue will also be delayed (which is of course a bike route).

    Hard to believe any of those places are as bad as Church + Duboce.

  • Used to live on 19th at Judah for a little while. You don’t understand what “endless roar” really means until you’ve lived on 19th Avenue.

    This reminds me of the West Portal tunnel construction in late 2007, where I commuted home after 9 during closed hours. So glad I ride my bike now – it’s really difficult to be inconvenienced by construction! What traffic jams?

  • They replaced the tram tracks in our neighborhood over the summer. Here’s my web page with descriptions of the process and links to videos. Maybe interesting to compare Vienna’s approach to San Francisco’s.

    Vienna has one of the world’s largest tram (streetcar) systems and they are justifiably very proud of their maintenance and reconstruction.

    For history buffs, they still operate PCC like trams from probably the 1950s that feature wooden floors and wood paneling elements … rolling history. Here’s a link to a YouTube video I made on our route:

How Public Q&A Sessions Can Obscure Support for Street Changes

When it comes to gauging support for changes on our streets, it’s easy to get the impression at community meetings that a handful of vocal critics represent significant opposition. But as preliminary survey results from a recent Inner Sunset meeting on improvements for the N-Judah show, public forums can often be a poor reflection of the actual level of […]

SFMTA Pushes Red Transit Lanes on Church Street to January, Citing Rain

Red-colored transit-only lanes on Church Street won’t come until some time in January, according to SF Municipal Transportation Agency spokesperson Paul Rose, who cited rainy weather as the reason for the delay. The project would be one of San Francisco’s first to add transit-only lanes with colorful pavement to emphasize that they’re off-limits to drivers. […]

In Struggle for Accessible Muni Metro Stops, Parking Comes First

The accessible outbound platform at Church and 30th Streets. Photo: Michael Rhodes "Stops are too close together on Judah Street" goes the common refrain among many of Muni’s N-Judah riders — at least the able-bodied ones. Barely 300 feet of relatively flat terrain separates two stops in an especially egregious case. But for Tatiana Kostanian, […]
