Sudbury Town Council will liaise with its counterpart in Halstead in a bid to get a bypass built.
Calls for a bypass have persisted for years but have stalled, with Suffolk County Council stating the money for the project is simply not available.
At a highways and footpaths committee meeting, councillor Tony Platt said he was considering launching a campaign in order to get a bypass built.
“Although various developments have been talked about, we are not getting many positive vibes about the bypass and the reduction of HGV traffic,” he said.
“This needs to be a medium-term priority at the very least, and we don’t want to it being kicked into the long grass.
“If we campaign for it, we would be seen to be doing something, even though it will be a long way off.”
One of the key arguments for creating the bypass is to help cut the levels of air pollution in Cross Street, where HGVs account for 40 per cent of emissions.
Councillors said that in order to move plans for a bypass higher up the county council’s agenda, they should talk with members of Halstead Town Council, which is also keen to see heavy goods vehicles rerouted around the town.
“We need to engage with Halstead to see if we can have a joint approach to the traffic problems surrounding our towns,” said Jack Owen.
Council clerk Sue Brotherwood said she was disappointed county council proposals to redirect traffic through Cuckoo-Tye – a junction on to the A12 from Great Horkesley – had not been pushed through a number of years ago.
