131002_1125_SB_Tunnel

Tunnel construction continues beneath 4th Street with our first tunneling machine, Mom Chung. Our second tunneling machine, Big Alma, launches in the coming weeks.

During the next 10 days, tunneling and tunneling preparatory work will continue in SoMa, Union Square and North Beach. Work to prepare for station construction is continuing in Chinatown and northern SoMa.

For descriptions of construction impacts in each neighborhood, click here or on the links below. We also post construction, traffic detour and Muni impact information on our project Google Map.

Construction impacts are planned to change at these locations by October 14:

  • Northern SoMa (Market to Harrison):  All lanes are now open to traffic on 4th Street between Market and Stevenson. On 4th Street between Folsom and Harrison, the parking lane and one lane of traffic on the east side of the street will remain closed to allow for ground improvement work. On 4th Street between Howard and Folsom, one lane will remain closed to traffic south of Clementina. Demolition of the 76 gas station in progress.

Several parking spaces will be closed near the intersection of Stockton and Washington and adjacent to the future Chinatown Station site 9933-949 Stockton). The sidewalk adjacent to the building will remain closed to pedestrians.

At these locations, current construction impacts are planned to continue until
October 14:

  • Southern SoMa (Harrison to King/Berry): 4th Street between Harrison and Bryant may fully close some evenings and weekends to allow for the installation of tunneling components and piping. Two lanes of traffic will remain open at all other times. Contact us at central.subway@sfmta.com if you have questions about the closure schedule.

Now starting: Construction of Central Subway stations, tracks and operating systems

Building-with-Wrap

This building in Chinatown will be demolished soon to make way for the Central Subway Chinatown Station.

Last month, we started the first construction activities to build the Central Subway’s stations, tracks and operating systems. This work will extend the Muni Metro T Third Line underground to improve public transit in some of San Francisco’s busiest neighborhoods. Once in operation, the Central Subway will cut travel times in half along congested Stockton Street and 4th Street while enhancing connections to BART, Muni Metro and Caltrain.

The first construction activities are preparatory in nature and include installing monitoring devices, putting up fences and removing hazardous materials at future subway station sites in Chinatown and SoMa. After completing this work, contractor Tutor Perini will demolish the existing structures at the sites of the future Chinatown Station (933-949 Stockton Street) and Yerba Buena/Moscone Station (260-266 4th Street). Station construction will follow.

At other locations, construction will commence later this year or in 2014. Construction timelines and impacts will vary significantly at the various project sites (more details below). Construction is expected to finish in 2018.

UMS Rendering - SE view - Sept 2012

Over the next few years, we will build the Union Square/Market Street Station on Stockton Street. This rendering shows the station entrance that will be built in Union Square Plaza, at the corner of Stockton and Geary.

The construction is part of SFMTA Contract 1300 (Stations, Track and Systems), awarded to Tutor Perini, a leading California-based construction firm, earlier this year. As part of this contract, Tutor Perini will construct three subway stations, one surface-level station, 1.7 miles of train tracks and the operating systems for the T Third Line extension.

Tutor Perini has extensive experience in building public infrastructure in the Bay Area and around the country. Tutor Perini improved the seismic reliability of the Richmond Bridge and is currently building the expansion of the Caldecott tunnel in the East Bay, among numerous other major projects.

To inform local businesses, residents, property owners and community groups about construction timelines and impacts, the SFMTA and Tutor Perini will work in partnership to disseminate  information and host community meetings before major work begins. The public may learn about Central Subway community meetings and construction by signing up for the project’s weekly construction emails. An online signup form is available at http://eepurl.com/oOs-b.

Construction will take place at the sites of the four new stations, an on 4th Street south of the 1-80 overpass.

Beneath the Pagoda Palace, foundations of San Francisco’s history

john+fatherjohn

Father John Takahashi and Central Subway Program Director John Funghi stand beside concrete blocks that once formed the foundation of a historic North Beach church.

Earlier this month, construction crews demolishing the Pagoda Palace unearthed a long-lost piece of San Francisco history: the foundations of a church that stood on these grounds more than a century ago.

The Holy Trinity Orthodox Cathedral, now located at 1520 Green Street, once stood in North Beach at the corner of Powell Street and Columbus Avenue. Built in 1888, the dramatic onion-domed structure was completely destroyed by the great San Francisco earthquake and fire of 1906. All that remained were five bronze bells – and they survived because they were off site at the time, being repaired. The church relocated to the Green Street location soon after, opening in 1909.

Last week a concrete block from the old church’s foundations joined the bells at the Green Street cathedral. After construction crews unearthed the foundations, we contacted Father John Takahashi, the senior priest of the Holy Trinity Orthodox Cathedral, to inform him of our discovery. We also invited him to visit the construction site and see the newly uncovered relics of his church’s past.

The Holy Trinity Cathedral on Powell Street, circa 1890.

Once on site, Father John spoke with Central Subway Program Director John Funghi, and the Central Subway team gave Father John a block of concrete from the old foundations. The block will now live in the garden of the Green Street cathedral.

Central Subway crews discovered the historic foundations while dismantling the thick concrete slab that formed the base of the Pagoda Palace Theatre. Once the slab was removed, the outlines of the foundation revealed themselves amidst dirt and rubble.

Archeologists and construction personnel examined the unearthed foundations and concluded that they were consistent with building practices in the late 19th century. The absence of rebar, the consistency of the concrete and the size of the aggregate in it helped support this conclusion.

With a piece of the old church now safely preserved, crews then broke apart what remained of the foundations to make room for the next phase of Central Subway construction, and the next chapter in the life of this storied North Beach site.
