Big changes coming as Calliope Crossroads work continues

CONSTRUCTION works at the Calliope Crossroads project have marked their one-year milestone ahead of major traffic changes on September 12.

Transport and Main Roads Department acting regional director Eric Denham said the $150 million project was on track to significantly improve safety and traffic flow at the notorious Bruce Highway intersection, west of Gladstone.

"As the project marks its one-year anniversary, site works will accelerate and there will be major traffic changes ahead of the new interchange opening early next year," Mr Denham said.

Since August last year, more than 75% of earthwork excavation for the project has been completed.

More than 140,000 cubic metres of embankment material and 45,000 tonnes of road pavement for the realigned Bruce Highway and Dawson Highway have also been put in place.

Works on the new bridges forming the Bruce Highway overpass and loop roads have advanced significantly.

Above-ground works on the structure are now visible and 22 bridge girders have been installed.

Mr Denham said with just six months of construction remaining, motorists could expect further traffic changes, particularly as works focused on completing the bridges and loop roads for the new interchange.

"The most significant of these will occur on the evening of Thursday, September 12, when traffic will divert onto the new on/off ramps," he said.

"The temporary traffic arrangements will operate much like a large roundabout, with designated lanes provided for vehicles accessing the Dawson Highway.

"Normal road rules will apply. The major change for motorists is after the traffic switch, crossing the Bruce Highway is completed in two stages."

Delays are expected when the traffic changes are first introduced, but travel times should return to normal once motorists become familiar with the short-term arrangements.

Mr Denham said delivering such a major project in a heavily congested location was a big challenge.

"Traffic control has been a focus at the Calliope Crossroads since day one - with school transport, industry workers, and long-distance freight all needing to be catered for," he said.

"So far drivers have shown great patience and understanding as we work towards building a better and safer road network for the region."
