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.

22^nd
Street Bridge

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

The closure of 22^nd Street between Iowa Street and
Pennsylvania began on Tuesday, April 19, 2016. During the closure, vehicular access to 22^nd
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 22^nd Street.
The temporary pedestrian bridge is intended for use by Caltrain customers
accessing the 22^nd 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.

650.508.7726; visit the website at www.caltrain.com/sfrb

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

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.
