THE Gladstone Marina (Matthew Flinders) Bridge will close to all road, pedestrian and tall marine traffic from 6am to 6pm on Thursday, June 12.
Gladstone Regional Council engineering services portfolio spokesperson councillor Rick Hansen said the one-day closure was necessary to enable further essential repairs.
"The works are required to rectify a failure occurring with the bridge locking mechanism and have been planned to remedy this problem as soon as possible," Cr Hansen said.
The bridge will remain in the horizontal position throughout the day and the road will be completely closed to all pedestrians and vehicles.
"Motorists affected by the closure should plan to use alternative road access via Hanson Road and Alf O'Rourke Drive during this time," Cr Hansen said.
"Operators of tall marine vessels are advised that passage under the bridge will not be available with the bridge unable to be raised during the closure. Small marine vessels however will not be affected."
Cr Hansen said the council was appreciative of the understanding of bridge users while the urgent works were undertaken.
"Council realises this is an inconvenience and sincerely apologises in advance of the works," he said.
"Council gives careful consideration before implementing a full bridge closure but unfortunately the hydraulic nature of these works requires the bridge to be closed."
