The Request For Proposal (RFP) for the Public Art associated with the new 12 Street S.E. Bridge has now closed. All submissions will be evaluated by a jury, which includes community members and professional artists as per The City’s Public Art process.
Access is limited to pedestrians entering the Zoo Administration Building and the South Security Gate with a valid Zoo membership or resident card and vehicles approved to access the Zoo Administration Building.
Regular inspections of the existing 12 Street S.E. Bridge are ongoing, and we will continue to update you as the project progresses.
General construction impacts
- Large trucks and other equipment will be moving in and out of the area.
- There will be beeping noises when trucks back up – back-up beepers are required for safety reasons and cannot be turned off.
- There will be general noise associated with construction.
- Every effort will be made to keep dust to a minimum.
Road and pathway closures
- The south pathway from 8 Street S.E. to New Street will remain closed during bridge construction work
- Large trucks and other construction vehicles will be moving in and out of the area. Entry into the construction area is not allowed.
- Pathway closures are implemented when they are necessary for construction. The detour must be along a sidewalk for pedestrians or along a roadway for cyclists.
- See the Zoo Flood Mitigation Project for information on Zoo Road and pathway closures and detours around the closed areas.
- The structural steel for the bridge will be fabricated in British Columbia and is scheduled for installation in the spring of 2017*.
- The concrete bridge deck will be installed after the structural steel is in place.
- The new bridge is scheduled to open to traffic in late 2017*.
- The old bridge is scheduled to be removed after the new bridge is open.
*Construction work is dependent on weather and other conditions. Dates may change. Changes will be posted on the project web page and communicated via other channels.

What will the new 12 Street S.E. Bridge look like?
The new bridge design to replace the existing 12 Street S.E. Bridge was presented at an Information Session on Wed., Dec. 2, 2015. See the twodrawings of the new bridge design.
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.
The bridge will be replaced starting in 2016 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.
- 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.
(as of September 2016)

The 9 Avenue S.E. Bridge will also be replaced because of age and condition issues, but construction will not begin until the 12 Street S.E. Bridge Project and the Zoo Flood Mitigation Project are completed. Anticipated construction start is 2018. Visit the project web page for more information.
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.
