Notice for the Week of July 7 to July 13, 2018

PG&E Pipeline Relocation Work
PG&E is relocating a natural gas pipeline for the 25th Avenue Grade Separation Project. The project will improve safety and reduce local traffic congestion. On Saturday, July 7 through Friday, July 13, S. Delaware will be closed between 25th Avenue and Landing (the intersection at Derby will be closed and 28th Avenue and Landing will be open to local traffic). 

To view a map click here (see pages 2).
Vehicular through traffic will be routed to Saratoga.
Pedestrians can access the eastern sidewalk on S. Delaware between 25th and 28th from those intersections.  

PG&E will clearly mark all work areas, and traffic flaggers will help to direct traffic. Please plan for minor delays and detours when driving through this area. Businesses on S. Delaware will be open as usual. For Nueva School access, please see the map at www.caltrain.com/25thgs/PGE. If you have any questions please contact your local PG&E representative Scott Hart at 650-598-7416 or send an email to gasprojectinfo@pge.com.

Grade Separation Night/Weekend Work

On Monday, July 9 to Friday, July 13, crews may be hauling dirt to construct a temporary parking lot at Pacific Blvd. and S. Delaware. 

Grade Separation Weekday Work
On Monday, July 9 to Friday, July 13, there will be partial lane closures on E. 25th Avenue between El Camino Real and S. Delaware. Street parking may be limited and flaggers may be assisting with traffic coordination at the railroad crossing. All businesses along E. 25th Avenue will remain open during construction. Caltrain will establish signs for pedestrians and motorists to help with traffic flow.

In addition to the PG&E pipeline relocation work (described above), on Monday, July 9 to Friday, July 13, crews will: 
Work on the abutments at 25th and 28th Avenues
Conduct field measurements at the Hillsdale bridge
Install piles at 31st Avenue
Excavate at Borel Creek and 25th Avenue 

Also on Thursday, July 12 and Friday, July 13, crews will be setting girders at the Pedestrian Underpass. 

Please note that crews are currently relocating fiber optic cable at Pacific Boulevard and due to the nature of this work, the road between Concar Drive and 19th Avenue will be closed to vehicles for approximately two months. Pedestrian access will be maintained during the closure. For a map of the road closure, click here

To view how to access the temporary lot during this phase of construction visit www.caltrain.com/25thgs (scroll down to “Project Resources”). We apologize for any inconvenience while this important safety improvement project is being constructed. 

Caltrain, in cooperation with the City of San Mateo, will raise the tracks and slightly lower the road (grade separate) at E. 25th Avenue in San Mateo. This will improve safety for both motorists and pedestrians, and it will reduce local traffic congestion in San Mateo. In addition, the project will create new east-west street connections at 28th and 31st Avenues; and as part of the project improvements, Caltrain will build a new elevated Hillsdale Station with updated amenities at E. 28th Avenue. 

Construction is expected to be complete in early 2020. In order to maintain regular train service, some activities will be conducted during nights and weekends, outside of normal train service hours. Neighbors may experience construction noise and light during these times. We apologize for any inconvenience this may cause.
