Cotter Dam has moved to the top of the list of outdoor walks to explore in the ACT thanks to a major development of the site that includes a visitor precinct and discovery trail.

The Enlarged Cotter Dam Project is one of the largest infrastructure projects to be executed in the ACT and it allows visitors to explore the surrounding area and view the new dam wall from a unique aspect.

Fleetwood Urban is proud to have been part of this exciting development and to have undertaken the design and execution of two pedestrian bridges, as well as boardwalks, shelters and public amenities.

Cotter Dam is located in an eroded valley comprised of indigenous rock and Fleetwood’s work on this project included assessing, repairing and certifying a bridge after a major flood event.

We installed a Stirling™ cable-stayed pedestrian bridge product across the Cotter River, which has length of 30m and a width of 2m, and is composed of hot dipped galvanised steel towers and frame, and both hardwood timber and fibre reinforced plastic decking. We also converted and redesigned an existing amenities building in a way that respected the original structure.

The location presented various challenges, one of which was the submarine foundation construction. Access to one end of the bridge only meant that the components of the bridge were fabricated off site and assembled on site using a mini crawler crane. A sequenced crane lift was used to install the Stirling™ bridge.

This has been a fantastic project for Fleetwood and a great opportunity to work with the ACT government to create a beautiful new location that can be enjoyed by locals and visitors to the area.
