Construction

 

San Francisco Roadway Bridges Project

Night/Weekend Work

There is no night or weekend work currently scheduled for the San Francisco Roadway Bridges Project.

 

Weekday Work

* In general, all weekday construction activity will occur between 7 a.m. and 5 p.m. on Monday through Friday. Neighbors may experience construction noise during this time. We apologize for the inconvenience.

 

22nd Street Bridge

Tuesday, December 27 to Friday, December 30, crews will continue work on the abutment at the 22nd Street Bridge location.

 

The closure of 22nd Street between Iowa Street and Pennsylvania began on Tuesday, April 19, 2016. During the closure, vehicular access to 22nd Street between Iowa Street and Pennsylvania Avenue will remain closed during the removal and replacement of the bridge. Detour signage will be in place to direct vehicular and pedestrian traffic during the closure.

A temporary pedestrian bridge has been installed to maintain limited pedestrian access across 22nd Street. The temporary pedestrian bridge is intended for use by Caltrain customers accessing the 22nd Street Caltrain Station.

Background
Caltrain is preparing to remove and replace the existing vehicular/pedestrian bridges over the Caltrain tracks at 22nd Street, 23rd Street, and Paul Avenue in San Francisco. Existing abutments will also be retrofitted to support the new structure. Utilities supported by the bridges will be temporarily relocated during bridge removal and construction.

The three bridges are deemed structurally deficient, do not meet existing seismic safety standard and must be replaced to ensure the safety and well-being of community members and Caltrain passengers.

San Carlos Transit Center Project
Tuesday, December 27, to Friday, December 30, crews will begin improvements to the south Caltrain parking lot. Crews will remove medians, pave and restripe lot.

On Tuesday, December 27, the south parking lot at the San Carlos Caltrain Station will be closed to traffic and parking. Because there will be limited parking in the north lot, customers are asked to park at the Belmont Caltrain Station.

Some parking spaces in the Caltrain parking lot and along the eastside of El Camino between Cherry and Arroyo will be removed permanently as part of the project. On-site notices will be provided at least 72 hours in advance before the removal of parking.

Background
The San Carlos Multi-Modal Transit Center Project (Transit Center) is located on the west side of the railroad corridor at the site of the existing San Carlos Caltrain Station. The Transit Center project consists of transforming the existing San Carlos Caltrain Station parking lot into a multi-modal transit center that will better serve the community by improving safety and accessibility between SamTrans fixed route bus services, Caltrain commuter rail services, local shuttles, pedestrians and bicyclists. For more information on the project, please visit
www.samtrans.com/sctc.

The Transit Center project is part of the larger mixed-use transit-oriented development, the San Carlos Transit Village, which is a joint development between SamTrans and Prometheus Real Estate Group.  For information about the San Carlos Transit Village Project visit:  http://cityofsancarlos.org/planning/projects/san_carlos_transit_village/default.asp

Los Gatos Creek Bridge Pre-Construction Utility Work

Night/Weekend Work

There is no night or weekend work scheduled for the project at this time.

Weekday Work

There is currently no work scheduled at the Los Gatos Creek Bridge site.

For more information on the Los Gatos Creek Bridge Replacement Project, please visit www.caltrain.com/losgatos. Construction for the bridge replacement is expected to begin in Early 2016.

Installation

Communications Based Overlay Signal System (CBOSS) Positive Train Control (PTC) Project

The CBOSS PTC Project is an advanced signal system that will equip the corridor and trains with federally-mandated safety technology and will increase system capacity to help accommodate future ridership demand.

The project will monitor and, if necessary, control train movement in the event of human error. This will increase safety by:

  • Eliminating the risk of train-to-train collisions.
  • Reducing risk of potential derailments by enforcing speed limits.
  • Providing additional safety for railroad workers on the tracks.

 

  • Improving grade crossing performance to reduce gate downtime and improve local traffic circulation.

 

The CBOSS PTC Project is also a key component of the Caltrain Modernization Program, which will electrify the Caltrain Corridor by 2020. An electrified Caltrain will be cleaner and quieter and will upgrade the system to provide faster and/or more frequent service to more stations and riders.


To implement the project, Caltrain will be identifying utilities, digging a small trench and/or boring close to the tracks to install fiber optic cable. In order to maintain daytime train service, Caltrain will be performing some of this work at night.

Maintenance

Caltrain will perform routine maintenance at several locations next week. To avoid disruptions to service, the work will mainly take place Saturday through Friday from 8 p.m. to 6 a.m. For more information about this type of work, click
here, or call 650.508.7726.

San Francisco to San Jose

Tuesday, December 27 to Friday, December 30, crews will pressure wash and perform janitorial work at Caltrain stations between the San Francisco and Tamien stations.

 

South San Francisco to Burlingame

Tuesday, December 27 to Friday, December 30, crews will resurface rail between the South San Francisco and Broadway stations. Resurfacing corrects the alignment of uneven rails to make them smooth, minimizing the jerks and bumps experienced by passengers and reducing the mechanical strain on the rails. Neighbors may experience construction noise during this time. Crews will work as quietly as possible.

 

Burlingame to Belmont

Tuesday, December 27 to Friday, December 30, crews will replace ties between the Broadway and Belmont stations. Caltrain uses several different on-track, self-propelled machines to replace cross ties, and neighbors may experience construction noise during this time. Crews will work as quietly as possible

 

San Jose

Tuesday, December 27 to Friday, December 30, crews will weld and grind rail near the San Jose Diridon Station. The welding crew uses air compressors, gas-powered generators, small power tools, electric-arc welders and propane heaters. Neighbors may experience construction noise during this time. Crews will work as quietly as possible.
