The region's MPs have spoken of their opposition to the government's plan to upgrade the A14 during a Westminster Hall debate.
Suffolk Coastal's Therese Coffey and Ipswich MP Ben Gummer are among those to have raised objections so far.
They say Suffolk is united in its concern about the plans which the MPs claim will be a tax on the area's drivers.
The government's plan to upgrade the A14 includes creating a new £1.5 billion toll road between Huntingdon and Cambridge.
The debate is taking place at Westminster at the moment with transport minister Robert Goodwill answering questions.
