Kimberley Bridges

Project Overview

Fortec successfully completed the Design and Construction of two bridges in the remote and beautiful Kimberley Region of Western Australia, 3,000 km north of Perth.

The bridges were constructed with non-traditional post-tensioned TeeRoff beams, varying in length from 26 to 29 m.

The 68 –75 tonne beams were precast and transported 1,000 km by road to the bridge sites.

The bridge abutments were each supported by four 750 mm-diameter, 6–9 m-deep bored piles with a 1,500 mm rock socket.
