Highland Avenue Bridge

Phase II - Security Fencing

Security fencing was installed to enclose the east and west bridge abutments.  The design is based, in part, on concerns raised by neighbors about debris buildup under the bridge and easy access to the site.  We believe the “ClearVu” security fencing will provide the most attractive and durable safety enhancement to the Highland Avenue Bridge. It will be nearly invisible to drivers, pedestrians, and cyclists on northbound and southbound on San Jose Avenue. The ClearVu high-density security fencing is made of high-tensile mesh with openings too narrow for finger-holds and foot-holds, preventing climbing or cutting with standard tools, bolt-cutters, etc.

January 23, 2017
Public Works learned today the most recent timeline for receiving materials needed to make REPAIRS to the security fencing, as follows:

  • Manufacturer reviews drawings by Jan 27th
  • Manufacture fencing material by Feb 10th
  • Contractor receives materials by March 24th  

these dates are tentative and subject to change


January 11, 2017 - Security fence REPAIR will commence within the next 2 months.  The newly installed security fence was breached in October 2016.  The "ClearVu" manufacturer has agreed to provide a stronger fencing material to repair the damage.  

The materials have been ordered.  We anticipate repairs will begin by the end of March.

September 23, 2016 - Security fence installation continues under the Highland Avenue bridge.  Beginning next week, the contractor will mobilize to the west side of the bridge, at southbound San Jose Avenue.  Work is on schedule for completion by October 31st!  

Phase I – Traffic Railing Replacement Completed March 2016

June 11, 2015 - The Highland Avenue Bridge closed for 6 months of construction.  Traffic rail replacement work included, demolishing and replacing the traffic rails. The Highland Avenue Bridge spans over San Jose Avenue which provides connection to downtown and the 280 freeway.  The bridge closure was largely due to efforts to maintain safe access on San Jose Avenue for Muni light rail, vehicular traffic, bicyclists, and pedestrians. If the rails were not located on a bridge that spans over another roadway, the rail replacement work would most likely have been accomplished in two to three months. Before demolition work could begin, scaffolding was constructed on the bridge which included an overhang portion extending beyond the bridge. The overhang portion was designed to catch all debris from falling onto the traffic below on San Jose Avenue. 

Most of the scaffolding construction work had to be performed at night when traffic volume on San Jose Ave is low and Muni service would not be disrupted.  

Contractors worked over the Muni tracks early Sunday mornings and over San Jose Ave during weeknights.

September 2, 2015 – Crews began demolition work and replacement work.
December 5-6, 2015 – Scaffolding removed. Debris netting removed. 
December 8, 2015 - The Highland Avenue Bridge was reopened to traffic.

Fun Facts

The Highland Avenue Bridge was originally constructed circa 1929.  The arch structure and bridge lighting were added circa 1972.  In 2012, Public Works placed a polyester concrete overlay on the bridge deck.  Slope paving at the embankments was added in early 2014.
