The new Mount Crosby Vehicle Bridge project is part of Seqwater’s East Bank Flood Resilience Program delivering increased flood resilience of vital assets at Mount Crosby. 

Located 15 metres downstream of the weir bridge, the new bridge is approximately three metres higher than the existing bridge to better withstand flooding and will have dual lanes to improve traffic flow and ensure larger vehicles can cross safely.

The existing weir bridge will close as work occurs to lay the new bridge’s road surface and connect it to Allawah Road West and East, as well as local infrastructure and services – before opening to traffic soon.

With works set to take approximately six weeks (subject to weather and construction conditions), the alternate route is across the Brisbane River via Colleges Crossing on Mount Crosby Road.

In the event of wet weather or an emergency where Colleges Crossing becomes unavailable during the closure period, Seqwater has developed a procedure that will allow the weir bridge to reopen to traffic on short notice.

Seqwater is committed to minimising impacts throughout the works, including noise and traffic, and thanks the community for their understanding.

After the new vehicle bridge is complete, the weir bridge will be repurposed and open to pedestrians and cyclists at a later date.

Quotes attributable to Seqwater CEO, Neil Brennan:  

“Closing the Mount Crosby Weir Bridge marks the final construction phase ahead of the new vehicle bridge opening soon.

“Seqwater has worked hard to minimise impacts, including devising a plan to reopen the bridge on short notice in the event of an emergency or severe weather.

“The East Bank Flood Resilience Program is designed to improve flood resilience and connectivity in Mount Crosby, and we are pleased to see this critical project nearing completion.”
