The Westgate Pedestrian and Cycle Bridge spans the Northwestern Motorway (State Highway 16) and was built to provide greater access to facilities between the Manutewhau Walk Reserve and the Westgate Shopping Centre.
TBS Farnsworth was engaged by head contractor HEB Structures, to provide support in the fabrication and construction of this 209m long bridge Specifically TBS’ involvement in the work included:
- Fabrication and Coating of 200 unique posts which formed part of the handrail system and were a key part of the bridge’s architectural look.
- Site installation of the posts, stainless steel hand rails and 8km of stainless steel wire.
- Fabrication and installation of bridge expansion joints
- Protective coatings touch-ups to the bridge handrails
The eastern side of the bridge consists of a series of curves that follow the contours of a nearby stream. This meant each of the posts had to be fabricated specific to the area of intended installation. Once abrication was complete, each unique post had to be installed in the correct position to ensure that the curves of the bridge were visually appealing. The visual appeal of the bridge was a key goal for the project so the correct fabrication and installation of the components was critical.
The stainless steel handrails were bent offsite to the required radius and then further manipulated to suit during installation on-site ensuring a smooth transition around the bridges curves. The handrails were site welded and polished to a high finish.
All of the site work was undertaken at height, some of which was over the live motorway. The installation team followed rigorous procedures to ensure that they could work safely at height and without the risk of dropping any tools or materials onto the live motorway below.
