The Sandy Lane and Area Action Group has launched a petition for traffic calming measures to be put in on the A131 in Sudbury.
The last recorded figures in 2014 showed an average of 8,419 vehicles passing along the road on Ballingdon Hill each day.
Campaigners have suggested a raft of measures to combat the problem, including:
l Speed reductions to 20mph to increase safety and reduce emissions
l Vehicle-activated speed awareness signs
l Pedestrian and cycle way enhancements
l A speed camera on Ballingdon Hill to discourage overtaking.
Group chairman Theo Bird said: “I’m absolutely fascinated to see how progress is going with the western bypass promised in the recent district council elections by various elected members.”
John Sayers, Suffolk county councillor for Sudbury, said: “I fully support the need for calming measures on the A131.
“I hope that our town council will continue to liaise with Halstead with a view to asking highways and police authorities to assess this route and consider appropriate traffic calming measures and robust signage.”
