Bridge demolition milestone

Posted on October 2nd, 2018

The Logan Enhancement Project recently reached a major construction milestone, with the successful staged demolition of the Mount Lindesay Highway/Beaudesert Road bridges over the Logan Motorway.

The mammoth task involved demolishing four bridges over the Logan Motorway – two over the eastbound carriageway and two over the westbound carriageway – over 22 nights throughout August and September.

The four bridges were comprised of 210 concrete deck units, 400m of bridge barrier, 16 columns, six headstocks and four abutments.

Project Director, Andy Richardson, said the work required to demolish the bridges was incredibly complex and high risk, and ensuring the work could be done safely with minimal impact on customers, was paramount to the project team.

“The demolition was safely undertaken through a combination of overnight ramp and carriageway closures, with access maintained at all times via contraflow on the opposing carriageway,” Andy said.

“Every morning, at the completion of the nightshift, the road was inspected to ensure that it could be safely re-opened to the more than 50,000 vehicles that travel daily through the interchange.”

General Manager – Delivery QLD, Ian Sinclair, said the project team had also reached another significant milestone, with the opening of all the new on and off-ramps at the Logan Motorway/Wembley Road interchange.

“We now look ahead the demolition of the Wembley Road bridge over the Logan Motorway in mid-October,” Ian said.
