THE long-awaited Mitchell Freeway extension will open in just one month with a new design aimed to make traffic flow.
The Hester Avenue exit has been turned into a dogbone with two roundabouts on either side of the freeway.
It’s expected 40,000 cars will get on and off at the freeway intersection every day.
“We’ve introduced these roundabouts, we’ve done away with signals so no signalised intersections at the freeway,” project director Chris Raykos said.
“That, in turn, will improve traffic flow.
“The cost of signals, you’re looking at anywhere between $150,000 and $350,000 for a set.
“So we’re saving on that and we’re saving on maintenance of those signals.”
The Hester Avenue extension has added a further 6km to the Mitchell Freeway.
The project is on time and under budget at $236 million, with 80 per cent of that from GST revenue.
“As we all know, we’re getting a really bad deal on the GST,” Transport Minister Rita Saffioti said.
“So we need more funds from Canberra to deliver the infrastructure we need.”
The new intersection will open in August.
