As plans for a multi-billion pound road tunnel under the River Thames were announced, transport campaigners in Suffolk say other roads in the region are going short of vital funds.
Businesses along the A12 between Lowestoft and Ipswich say they are losing money because the road is so bad.
Suffolk County Council and East Suffolk councils have committed £500,000 to build a strategic business case to Government for funding to improve part of the A12.
Bypasses are needed for the villages Marlesford, Little Glemham, Stratford St Andrew and Farnham.

Police have warned that the Northbound section of the A12 will be closed until at least 1am tomorrow for repairs.
It comes after a lorry fire closed the road in Essex in both directions this morning.
There are fears it could be closed for longer.
Serena Sandhu reports.
Motorists taking the A12 through Essex will have to wait until July for all the roadworks to be finished.
The maintenance on the section near Brentwood has been going on since December and was supposed to be completed last month.
But the Highways Agency says the work has been more complex than originally anticipated.
It is one of two such schemes to overrun on the road - the other, near Ipswich, is due to finish by May.
Roadworks on two stretches of the A12 are going to be around longer than planned.
Resurfacing work that started in Ipswich and Brentwood in December was due to finish at the end of this month.
The Highways Agency said weather conditions and additional works had held up progress. The improvements are now due to be completed in May.
A section of the A12 around Chelmsford in Essex has been closed after a lorry overturned between Junction 17 at Great Baddow and Junction 15 for the A414. Drivers are being warned of very slow traffic.
Police in Essex have confirmed that a man in his 20s has been killed on the A12 in Essex.
The incident happened at about 3am this morning, the pedestrian was in collision with a number of vehicles.
Forensic recovery work is now taking place.
Because of that the northbound carriageway will be closed for most of the morning between the Boreham Interchange and the junction for Hatfield Peverel South.
One lane is also closed on the southbound carriageway which is also causing delays.
A man has died after becoming ill at the wheel and crashing his car in Essex.
Police were called to the A12 at Galleywood, near Chelmsford, just before 2pm on Friday.
Officers believe the driver of the car, a man in his 70s from Suffolk, became unwell and crashed into the central reservation between junctions 15 and 16.
No other vehicles were involved.
The man was treated at the scene by ambulance crews but later died.
A12 both ways closed, delays due to overturned lorry and fuel spillage at A1152 Woods Lane (Melton Roundabout). Quite a lot of fuel on the road, and the lorry on its side. Some traffic is already diverting through Melton and Woodbridge on the B1438.
One lane closed due to broken down vehicle on A12 northbound after J20a, B1137 (Hatfield Peverel South).
The A12 northbound is blocked due to an accident involving two vehicles between J20B B1137 The Street (Hatfield Peverel North) and J21 B1389 Hatfield Road (Witham South).
