Yaamba Road Pedestrian Bridge

650 cubes of concrete works plus 120 tonnes of steelwork. In situ.

Client: York Civil SA - QLD Department of Main Roads ECI contract
Location: Rockhampton QLD
Yaamba Road Pedestrian Bridge

Scope of Works

Steelink were retained to expedite the progress and control the quality of a significantly sized steel footbridge, while meeting the Department of Main Roads specifications.

The fabricator for the project was located in Brisbane and the construction site was in Rockhampton.

Additionally, the specified welded connection design was complex and challenging.

Project Specifics for Yaamba Road Pedestrian Bridge

The Yaamba Road Pedestrian Overpass was designed to enhance pedestrian access and provide a safe passage across the Bruce Highway – the busiest highway in Queensland. The overpass also improves long-term traffic flow within the busy North Rockhampton corridor.

York Civil was the principal contractor under an ECI model that delivered the design and construction of the overpass.

The 120t, 48m single-span steel truss was designed, constructed and then transported from the assembly yard (located a few hundred meters away at the local school) to the site and lifted into position over the highway. The unique structure is believed to be the longest span Vierendeel pedestrian crossing in Australia.

The project also involved mechanical and electrical services for lighting, lifts, security, an intersection upgrade, as well as brownfield construction.

York Civil won Civil Contractors Federation Case Earth Awards – Category 3 Project Value between $5 and $20 million (Queensland) for demonstrating construction excellence throughout the project.

Project Features

The overpass was the project’s main feature and consisted of a 48m single-span Vierendeel steel truss bridge, a fully enclosed slim-line arched structure with stair and lift access for all-weather use. It was founded on four 1200mm and thirteen 45mm diameter bored steel lined piles. Key elements of the project included:.

  • Service relocations including overhead HV power
  • Intersection re-alignment whilst maintaining access for business and motorists at all times
  • 17 piles consisting of 125.8m3 of concrete ranging between 9m and 23m deep
  • 650m3 of in-situ concrete works including footings.
  • 120t steel fabrication and assembly including anti-throw screens and architectural elements
  • 2 x 17 person lifts
  • 24-hour CCTV coverage and emergency call functions
  • Designed to accommodate six future lanes along Yaamba road with a min. 3m deck width
