THE Department of Main Roads has released a concept plan to fix the well-known problems on the Cunningham Highway between Amberley and Yamanto, but are still awaiting Federal funding approval.

Dozens of serious crashes, several of them fatal, in recent years, in addition to daily congestion issues near the turn-off to the RAAF Base, has prompted calls from residents and the transport industry for long-overdue improvements.

Another serious crash involving a truck and car yesterday at the intersection of the Cunningham Highway at the Southern Amberley Rd intersection further exemplified why a fix is needed.

The Department of Main Roads says detailed engineering has gone into the concept plan for improvements, which will include a realignment of the highway, an upgrade of the intersection of the highway and Ipswich-Rosewood Rd, restricted access to Middle Rd, an overpass over the new connection road, a new service road from Ipswich-Rosewood Rd to Warwick Rd, and new pedestrian and cycling facilities.

The Department of Main Roads says the upgrades were submitted to the federal government in mid-2012 for funding approval for design and construction. The department is awaiting the outcome of the funding request.

It is understood the State Government is seeking an 80/20 federal/state split.

"The project is the first step in enabling the future Western Ipswich Bypass and will help reduce congestion, improve safety and provide greater efficiency for freight along the highway," the Department website says.

Willowbank Area Group president George Hatchman said he'd been told the project would cost $340 million with an estimated timeline of 5-7 years for funding and the start of works.

He said about 17,000 vehicles used the troublesome intersection each day, including 2500 heavy vehicles.

Tow truck driver Chad Hayes said various governments created designs for upgrades only to let the proposals go to the scrap heap.

"The condition of the highway and congestion affects the travel times of transport companies and also causes the traffic to be backlogged five kilometres at times between 5am and 7am each morning whilst motorists travel along the Cunningham Hwy to turn off at the Amberley turnoff," he said.

"This is a two lane national highway that has in excess of 5000 vehicles traveling along it each day."

Mr Hayes is now calling on truckies who travel along the Cunningham Hwy to speak up about the upgrade plan that will see the BP service station at Amberley and the Matilda Truck Stop at Willowbank bypassed.
