That bid is for major improvements to the Nacton Road junction with the Ravenswood housing estate, the A1189 towards the A14 and the Ransomes Industrial Estate in Ipswich.
While a decision on that request has not yet been made, it would be bolstered by local funds, according to a report by the Ipswich Star.
Ipswich MP Tom Hunt said last week that the Department for Transport should look favourably on the proposals.
He said: “Over the summer I carried out a survey in Ravenswood and by far the number one issue was the access. In fact, there is only one access point at the Thrasher roundabout onto Nacton Road.
“It can be a game-changer in regards to this issue,” and added it would “make life better for Ravenswood residents who currently have to put up with unacceptable levels of congestion every day when they look to leave their community to go to work, drop off their kids, or whatever else it is.”
