Avoid Congestion Caboolture River Bridge Works road diversions begin June 27
"Traffic has been switched onto the northbound bridge from Monday 27 June 2016, with one lane of traffic operating in each direction.
Alternative South bound traffic diversions have already been constructed and is now in use as of Monday June 27.
Here is a final look at the old bridge before it goes.
Blast walls have also been erected when demolition of the old bridge commences shortly.
"The contractor will then get to work demolishing the southbound bridge to allow for the new bridge to be built in the same location.
"The new two-lane bridge will include a three-metre shared pathway that will provide a great new facility for pedestrians and cyclists."
Mr Mallows said the project team had been working hard behind the scenes to identify strategies to manage the congestion and delays expected during construction.
"Additional CCTVs and webcams have been installed to monitor traffic and allow signal timings to be adjusted where possible to help minimise impacts," Mr Mallows said.
"Mobile electronic message boards are also installed near the bridge and at strategic locations around the local network to inform motorists about potential delays.
"A reduced speed limit will be in place, as well as new linemarking, barriers, and signage to guide motorists safely through the site.
The Northbound bridge had alternative markings already painted on the road earlier ready for the switch over Monday June 27.
Here is a view for north and southbound traffic with road markings who from now on until completion will share the northbound bridge.
"Every effort will be made to minimise the impacts on the local community and we thank you for your cooperation and patience during these important bridge improvement works."
Construction is scheduled to be completed within one year, weather permitting.
To avoid traffic delays during works, motorists are encouraged to:
* avoid the bridge site and take alternate routes, such as the Bruce Highway
* avoid travelling during morning and afternoon peak hours
* use online traffic tools or apps to check live traffic conditions and find the quickest route before departing.
