Fourth and Fifth Avenue Bikeways Construction Update

SANDAG Fourth and Fifth Avenue Bikeways Construction Update October 2020

The following information was shared with the Mission Hills Parking Advisory Committee by SANDAG. While this project is not directly located within Mission Hills, the affected area is a thoroughfare from downtown to Mission Hills and the Uptown areas, therefore, construction may affect the parking and transportation within Mission Hills.

Recent Construction Activities

Over the past month, SANDAG crews continued construction of the Fourth and Fifth Avenue Bikeways in the City of San Diego. On Fifth Avenue between Fir and A streets, crews constructed concrete curbs to form median islands that will separate the bikeway from the parking and travel lanes. Crews also identified underground utility locations and performed roadway demolition and paving activities at various locations along Fourth and Fifth avenues. 

Upcoming Construction Activities

SANDAG crews will continue construction work along Fourth and Fifth avenues in Downtown San Diego and Bankers Hill. 

Fifth Avenue:

  • A Street to Cedar Street: Crews will install temporary striping and remove traffic control.
  • Cedar Street to Fir Street: Crews will pave around the newly constructed median islands.
  • Fir Street to Ivy Street: Crews will perform roadway demolition and begin to form and pour median islands. 

Fourth Avenue:

  • Ash Street: Crews will complete construction of the curb ramp on the northeast corner of the intersection of Fourth Avenue and Ash Street and will form and pour median islands.
  • Cedar Street: Crews will begin roadway demolition on the west side of Fourth Avenue and Ivy Street and complete construction of the median islands on the east side of the street. 
  • Cedar Street to Fir Street: Crews will perform roadway demolition and begin to form and pour median islands.

What to Expect During Construction

  • Most work will occur Monday through Friday, holidays excluded, between 7 a.m. and 5 p.m. Occasional Saturday work may be required.
  • Lane closures, traffic control, parking restrictions, and pedestrian detours will be in effect.
  • Temporary bike lane closures: Bicyclists will be routed to the adjacent vehicle travel lane to bypass the existing bike lanes where crews will be working. Alternatively, people biking may choose a parallel route using the bike lanes on Sixth Avenue.
  • Access to businesses and driveways will be maintained.

Crews will minimize impacts to the maximum extent possible. Please note, construction schedules are subject to change.

Construction notices will be posted online at

About the Project

The Fourth and Fifth Avenue Bikeways project will add more than 4.5 miles of new bikeways that will make the streets safer and more pleasant for all users. They will provide a vital connection for residents to walk and bike between vibrant communities within San Diego’s urban core including Hillcrest, Bankers Hill, and Downtown San Diego.

Project features will include separated bikeways, buffered bike lanes, bike boxes, high-visibility crosswalks, and other traffic calming measures.

The Fourth and Fifth Avenue Bikeways project is a critical component of the SANDAG Regional Bike Plan Early Action Program (EAP), an initiative approved by the SANDAG Board of Directors in 2013 to construct a regional network of high-quality complete streets and bikeways that will make walking, biking, or using other forms of active transportation a competitive and attractive option for everyday travel. The proposed network reimagines how we use space on our streets to make them safer and more comfortable for every person who uses them, regardless of age, race, or physical ability.
