Here is what is happening on Folsom Street :

Construction is progressing steadily, with major paving and concrete work continuing through mid-May 2026. The most intensive impacts over the next several weeks will involve sidewalk reconstruction, roadway paving, and intersection upgrades, particularly between 3rd Street and 5th Street.

Segment 3 -Folsom Street 2nd St. to 5th St

• Roadway base-repair - 4th Street to 5th Street (Northside).  
  Roadway base repair restores the structural layer beneath the pavement that supports traffic and prevents surface damage. When the underlying base becomes weakened by water, heavy use, or ground movement, the pavement above it can crack, sink, or develop potholes.
  What the work includes
  •    Identifying areas where the pavement structure has failed
  •    Removing damaged asphalt or concrete
  •    Excavating weakened base material
  •    Installing and compacting new base aggregate
  •    Repaving the repaired section to match the existing roadway 

   

• Sidewalks, Islands & Concrete Work
  • 4th–5th Street:
    • North side flatwork: April 20 – May 13
    • Islands and roadway base: through mid-May
  • 3rd–4th Street:
    • Sidewalk (north & south) and island work: April 20 – mid-May
    • Bus island and bus pad construction at 3rd Street: late April – mid-May

Segment 2 - Folsom Street 5th St. to 8th St.

Project Description and Scope of Work:

SF Public Works has hired Mitchell Engineering to perform vital infrastructure improvements along Folsom Street between 2nd Street to 11th Street.  The Folsom Streetscape Project which began in May of 2024 has an overall duration of 2-years, 7-months (950-days). The Folsom Streetscape Project aims to improve traffic safety and livability along this important corridor. Folsom Street is part of the City’s Vision Zero high-injury network, making it a high priority for street-safety improvements. The Folsom Streetscape Project will transform the corridor, prioritizing non-motorized modes of travel.
 

We are aware of the inconvenience caused by construction and apologize in advance.  We will do everything possible to minimize the impact of our activities on your neighborhood.  If you have concerns (scheduled deliveries, construction questions, accessibility needs, and access) please contact Public Affairs, Dadisi Najib. 

Your cooperation will help this project be a success for your neighborhood and the City of San Francisco.  Thank you in advance for your understanding and cooperation.
