Protestors marched through the new one-way system in Bungay to make sure their opposition to it was clear.
They say that in the last week traffic and accidents have increased in the market town - and they're blaming it on the one-way system that started being trialled on 9 September.
Traffic is now only permitted south along Trinity Street and north along St Mary's Street.
Katy Wakley says the new layout makes it difficult for her to get around in her wheelchair.
Cllr Guy McGregor spoke to a number of protesters about their concerns.
He says the scheme was supported by Bungay Town Council and was introduced to improve road safety.
But some claim it's having a detrimental impact on local trade.
A decision will be made on the scheme's future in the next four to 18 months. But local traders fear their businesses may not be able to survive that long.
