The organisation - which brings together mayors of 10 different councils in the Central West - met at Bathurst on Friday, with transport and a third crossing of the Blue Mountains being the main agenda of the meeting.

Of major talking point was the third crossing and Mr Medcalf said he wants to see a plan for a third crossing sooner rather than later.

"A lot of us feel that we'll be lucky to see it in our lifetime, the way it's going," he said.

"You look at the Pacific Highway and how long it's taken to upgrade that.

"What we'd really like is something constructive put together in a plan. That's what we're aiming at doing."

Mr Medcalf said a number of parties spoke at the meeting, including Minister of Regional Transport and Roads, Paul Toole, who mentioned the $2.5 billion upgrade of the Great Western Highway between Lithgow and Katoomba, but Mr Medcalf said a third crossing is the best way forward.

"We're looking at all options. We're not closing eyes to anything, we just want 100 kilometres per hour. We don't want to be pulling up for school zones and 60 and 80 zones," he said.

"There was no motion put forward, but we definitely think the best option going forward is a third road over the Blue Mountains."

Mr Medcalf said there's plenty of economic benefits to have a high-speed crossing of the Blue Mountains.

"I think I could just about write a book [about how important a third crossing is]," he said.

"Not only in terms of progress for Western NSW from things such as manufacturing, but tourism as well.

"For the congestion that is in Sydney, there's an option to come out here and live too. With the way technology is these ways, people can live out here and work.

"It'd be easier for general freight too, going backwards and forwards. Imagine driving that road everyday?"

Mr Medcalf said he's hoping the Central NSW Joint Organisation could meet with a number of councils on the eastern side of the Blue Mountains, such as Penrith and Hawkesbury, in the new year.

The Central West NSW Joint Organisations previously backed a petition by the Western Link, which called for a "safe, swift link" through the Blue Mountains allowing motorists to travel at 100 kilometres per hour the whole way, or from Lithgow to Sydney's western fringes in 45 minutes.

Its next meeting is expected to be held in Blayney in the first week of March, with telecommunication to be the focus.
