The last beam has been lifted into place and installed by two cranes on the new Boyanup-Picton Road, or ‘Mega-Bridge’, overpass bridge on the Bunbury Outer Ring Road project.

Following a year-long construction process, the bridge now stands at 382m in length after over 60 beams, weighing in at over 200 tonnes and measuring in at 43m in length and 2.2m in depth, were successfully installed by crane crews. Among a range of different contractors, WA crane hire company Joyce Krane’s LG1750 and LTM 1750-9.1 can be seen completing a range of different lifts, with a telescopic crawler crane acting as the support for all of the lifts, due to the sheer size of the beams being installed.
In all, the beams required a combined 18 days of crane relocation and mobilisation as well as installation, utilising workers across both day and night to complete the work as quickly as possible. Main Roads WA, the leading body for the project, employed extensive traffic control across multiple roads to ensure safe and efficient installation could be completed with minimal disturbance.
Overall, the scope of the work included installing into the bridge 11 precast headstock shells for cross-support, 33 1.5m-wide and 7.5m-tall columns, 43 pile structures, and 60 beams made of 12-by-5 spans, requiring a range of different contractors to work across the job. The bridge is now the longest bridge in the entirety of the South West, according to Main Roads WA, and connects to the existing outer ring road that was built in 2013 as part of Stage One of the project.
News of Joyce Krane’s work on the Mega-Bridge for the Bunbury Outer Ring Road project follows on from Tutt Bryant Heavy Lift & Shift’s work in lifting 220-tonne beams late last year on the southwest of Western Australia’s largest infrastructure project.
