A debate is due to take place in the House of Commons tomorrow over proposals to toll part of the A14.
Business leaders and politicians have blasted the suggestions saying it will put a strangehold on Suffolk businesses.
Suffolk Coastal MP Therese Coffey has secured a debate in the House tomorrow.
Consultation over the Highways Agency scheme closed on Sunday.
But Bury St Edmunds MP David Ruffley said roads minister Stephen Hammond told him at a meeting last week, a decision is likely to be just before the New Year.
“That means there is still time for representations to be made and we are going to have another go,” said Mr Ruffley.
Alongside Ms Coffey and South Suffolk MP Tim Yeo, he is to meet with Secretary of State for Transport, Patrick McLoughlin in the next three to four weeks to discuss the tolling issue.
“We are just waiting for a date for that meeting,” said Mr Ruffley.
He said a ban on HGVs using what will become the old A14 – would leave them no choice but to pay the toll.
“It is not just businesses that are up in arms about the Government proposal to force drivers through the new A14 toll road around Huntingdon.
“I have been taken aback by the number of complaints from my constituents and councils in and around Bury, Stowmarket and Needham Market.
“Suffolk sees this as discriminatory. No other county in the United Kingdom is subject to such a compulsory toll proposal,” Mr Ruffley said.
“This is not just about protecting business for Felixstowe docks.
“It is about stopping Suffolk people having a tax imposed on them that isn’t being imposed on other counties.
“The proposal will lead to an unequal playing field and this is not acceptable to me.”
New Anglia Local Enterprise Partnership chairman Andy Wood has also written to the agency.
“The opposition to tolling from businesses and elected members from Suffolk and Norfolk should not be underestimated.” He said a toll would add costs to businesses in the East, not faced by competitors elsewhere.
Mr Wood also criticised the agency’s consultation – exhibitions took place only in Cambridgeshire.
“We are concerned that the toll will be a significant barrier to growth for our business community.
“We are also not convinced the revenues raised by the toll will make a significant contribution to the costs of the road.
“We urge the Government to think again about the tolling proposals and the negative impact they will have on our local economy.”
Suffolk Chamber of Commerce has already led a campaign against the tolling which is backed by the New Anglia LEP.
