The WestConnex Concord Rd to M4 West On-Ramp is a continuous, 5-span, 213m long twin steel composite girder bridge supported on mechanical steel pot bearings with a maximum span of 60m. It had to be designed for both vertical and horizontal curves, with a tight horizontal radius of approximately 80m. In addition, the steel girders sit on a constant 5% crossfall, while the road surface transitions from 5% to 3% superelevation. The constant cross fall means that through the horizontal curve, the bottom flange was fabricated in a conical shape.
