Bridge traffic heading for future gridlock
TRAFFIC congestion on the Grafton Bridge will continue to worsen until it reaches gridlock, according to a report prepared for the Clarence Valley Council.
Deputy general manager Des Schroder said the South Grafton Traffic Study, undertaken by the Roads and Traffic Authority and the council, showed afternoon congestion would eventually become worse than morning congestion.
It showed that in 2007 the average peak afternoon travelling times between Villiers and Ryan streets was five minutes 30 seconds. That is expected to rise to nine minutes in 2018 and to 20 minutes in 2028.
Morning peak period travelling times from Ryan Street to Villiers Street in 2007 were seven minutes and 40 seconds, rising to nine minutes in 2018 and staying at nine minutes until 2028.
All travelling times would be reduced to three minutes if a second bridge was built, the study found.
Mr Schroder said that some time before 2028 the queuing would reach a level where traffic spilled onto the Pacific Highway.
He said that raised safety issues, but those were outside the scope of the study.
“Quite clearly the single crossing of the river is the critical constraint to the network and the only way to ensure that the network performs to acceptable levels in the future is to provide an additional crossing,” he said.
