An AA report shows 40,000 more cars were on the city’s roads last year with the average commuter spending nearly 80 hours stuck in gridlock.
The Building Industry Federation’s chief executive Bruce Kohn said transport costs are up to twice those of other regions and building materials getting delayed by traffic is a growing problem.
This mans materials are not being delivered on time and to fit in with construction schedules.
“Congestion means trucking companies are turning more and more to smaller trucks, so deliveries are not as large as they previously were,” he said.
He said some freighting services have changed from set delivery costs to an hourly charge and there’s a reluctance to dispatch deliveries across town in the afternoon as they can quickly become caught in the end of day rush hour..
Kohn said he’s heard of truck drivers getting so fed up with being stuck bumper-to-bumper that they’ve given up the job.
