12 Street S.E. Bridge Replacement Project

Project update - April 2019

The final landscape work is scheduled to begin the week of April 21, 2019. It is anticipated that this work will take approximately two weeks. Construction work will include:

  • Installing a concrete bench in the seating area on the southwest side of the 12 Street S.E. bridge.
  • Cleaning-up landscaping that was damaged in the winter.
  • General work around the site.

Construction work is dependent on weather and site conditions, so timelines may change.

 

Project background

The original 12 Street S.E. Bridge that spanned the Bow River on the south side of St. George's Island needed replacement due to its age and deteriorated physical condition. The bridge, constructed in 1908, was originally designed to carry horse and buggy, as well as pedestrian traffic to St. George's Island. It provided an important link for vehicles and people on foot or bikes, and provided access to and from 9 Avenue S.E. to Memorial Drive. The new bridge will maintain this important link for the next 100 years.

The new bridge:

  • Provides two lanes for vehicle traffic with adequate lane widths, which can accommodate emergency vehicles and future Transit, and increase safety generally.
  • Is flood resistant.
  • Provides pedestrian/cycling access across the bridge and connects to the existing pathways on the north and south ends of the bridge.
  • Is easier to maintain and will last for a long period of time (100 years).
  • Incorporates a commemorative component that recognizes the old bridge design.
  • Continues to provide access into the Zoo's Administration area parking lot and building.
