Bow River Bridge
Cochrane's new bridge across the Bow River located near the SLS Family Recreation Center started construction in August 2018. The new bridge and the arterial road connections will also include on-street bike lanes and a separated, parallel 3 metre-wide multi-use pathway that connects with Cochrane’s existing pathway system. See the video rendering here.

- Starting August 7, 2018, a portion of the north end of Jim Uffelmann Memorial Park across from SLS Family Sports Centre will be closed to facilitate construction and connection to Griffin Road. Pathway users can use the paved detour around the construction site. There will likely be short disruptions while work is underway.

|This map shows the general location of the new bridge and alignment of the proposed James Walker Trail corridor (alignment will be finalized as part of the ongoing detailed design).|
The bridge is being designed as a three-span bridge with a single pier in the river, and the second pier adjacent to the river. The outer spans will be about 51m (165 ft) each with the central span being about 58m (190 ft). The piers have been designed with two columns to improve visibility for users beneath the bridge and the overall bridge aesthetics.

Conceptual illustration of the bridge design. In addition to two traffic lanes, the bridge includes bike lanes and a separated, 3 metre-wide multi-use pathway. A large lookout area above the eastern pier can be used to by cyclists and pedestrians to enjoy the view of the river.
Once construction of the bridge is complete, the beach and multi-use pathway under the bridge will be re-opened.

Start of construction of the in-river berm that will be used as a construction platform for the east pier of the bridge.
Sep 5, 2018
Construction of the temporary berm is complete (approx. 9500 m3 of cobbles). The berm will be used as a construction platform for the bridge piers and will be completely removed in summer of 2019 so the gravel beach can be reestablished.

Things are getting busy at the bridge with the start of construction of the in-river pier foundations. The foundations for each pier consist of eight drilled-shaft, cast-in-place concrete piles that are about 1.2m (4ft) in diameter and up to 13m (43ft) long. The cut for the east abutment on the far side of the river is also advancing with a further 4 m of cut to go.
