12 Street S.E. Bridge Replacement Project

Project update – January 5, 2018

The new 12 Street S.E. Bridge, Zoo Road and Baines Bridge are now open!

While we have completed most of the improvements, construction work will still be continuing in the area until summer 2018. This work will require temporary lane and pathway closures. Please continue to follow detour signs in this area.

Project background

The 12 Street S.E. Bridge spans the Bow River on the south side of St. George's Island and is in need of 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. Now it is an important link for vehicles and people on foot or bikes, which provides access to and from 9 Avenue S.E. to Memorial Drive and points south. A new bridge will ensure this important link is maintained for the next 100 years.

Project scope

The bridge will be replaced with a new structure that will:

  • Provide two lanes for vehicle traffic with adequate lane widths, which could accommodate emergency vehicles and future Transit, and increase safety generally.
  • Be flood resistant.
  • Provide pedestrian/cycling access across the bridge and incorporate into existing pathway on the north and south ends of the bridge.
  • Be easier to maintain and will last for a long period of time (100 years).
  • Incorporate an historical/commemorative component recognizing the old bridge design.
  • Continue to provide access into the Zoo’s Administration area parking lot and building.

Timeline

  • Preliminary design - fall 2015
  • Detailed design - winter 2016
  • Construction - spring 2016
  • Completion - winter 2017*
*Construction is very dependent on weather and site conditions. More information will be provided on updated timelines, but dates can change.

Budget

$26 million

Public Art

A project-specific public art selection panel has selected artist Brandon Vickerd for the development and execution of a permanent public art project adjacent to the new 12 Street S.E. Bridge.

Communication

The City of Calgary will communicate with the public and impacted businesses about the construction before it begins and on an ongoing basis throughout construction. The web page will be the primary source for updated information.
