Project Status

Updated: October 13, 2026

 

This project is in design and scheduled to begin construction in late 2027. The bridge closed to pedestrian traffic in October 2026 and will remain closed for the duration of construction. Long-term pedestrian access to the north side of 9th Avenue will be installed in early November 2026. Until then, pedestrians are encouraged to use the following detour routes:

  • Pedestrians heading west, should cross 9th Avenue at the mid-block crossing to continue travelling west on the south side of 9th Avenue.
  • Pedestrians heading east, should cross to the south side of 9th Avenue at the Collyer Street intersection.
  • The north and south access to the Spring Gulch #1 trail will remain open.

 

Project Schedule

  • Closure of the pedestrian bridge: October 2026
  • Long-term pedestrian detour installed: November 2026
