After three years of lobbying for the road infrastructure, Inverell Shire Council's "shovel-ready" project can begin.

All three tiers of government have contributed; $1.5 mil from local council, $1.5 mil from a federal level and now $2.2 mil in state funding.

Deputy Premier John Barilaro and Minister for Agriculture/ Northern Tablelands MP Adam Marshall were in Inverell yesterday to announce the state support.

Funded as part of the drought assistance package, Mr Marshall described the intersection as incredibly busy, made more complicated with unaligned roads and a busy service station drawing regular turning traffic.

"Without this project, the intersection is a disaster waiting to happen. This is also a freight pinch-point so it is important to get it happening.

"It is hoped by doing this, the roundabout will not only resolve some serious issues in the community, but provide an economic stimulus," he said.

The nightmare intersection becomes highly congested during peak times when families are driving to and from work, school and community events.

Deputy Premier Barilaro inspected the section of road almost two years ago and was delighted to return to announce the $2.2 mil contribution.

"We know the drought is biting hard so we hope this will stimulate local work," he said.

Mayor Paul Harmon said the project was something the community was desperately calling out for.

Confidential discussions are underway with the Liberty Service Station's owner and council to acquire some of the land to accommodate for the roundabout.

"Council staff are working with the proprietors of the service station to see how we can make the roundabout fit and the continuation of their business," he said.

As a highway under Roads and Maritime Services (RMS) control, council with the help of Mr Marshall had to push the importance of the project.

Mr Harmon said the project wasn't high on RMS' priority list but after a number of designs were submitted by council staff of possible options to make the intersection safer, RMS gave the green light.

"Our staff designed a number of concepts and presented them, once RMS came back with the preferred option, we endorsed it."

With funding secured and plans finalised council will endeavour to begin work as soon as it is practical.
