A14 Junction 55 Copdock Interchange
We are considering the proposed improvement of the A14 Junction 55 Copdock Interchange as part of National Highways continued investment in the East of England
Project information
The A14 Junction 55 Copdock Interchange is a grade separated junction in Babergh District, south-west of Ipswich. It is one of the key Strategic Road Network (SRN) junctions serving Ipswich via the A14, the A12 and the A1214 and is located 14 miles to the west of the Port of Felixstowe.
The A14 has national and international importance as it is part of the Trans-European Transport (TEN-T) Network, connecting the Port of Felixstowe on the east coast with the Midlands and beyond via connections with the M6 and M1.
The junction with the A12 provides access to Colchester, Chelmsford, London, the M25 and Stansted Airport to the south and the A1214 is a key route for accessing Ipswich and the A14.
The current variations in journey time reliability (that is, being able to accurately predict when individual vehicles will be arriving and departing) often present an unwelcome and potentially costly risk for freight moving to and from the Port of Felixstowe.
During peak periods, average speeds on the approaches to the Copdock Interchange are significantly less than the statutory limit. This results in unnecessary delays and queueing on the local road network. It is evident that the current demands on this section of the Strategic Road Network exceed the available capacity of the junction at crucial times and is likely to increase in the future. Such congestion also means significant numbers of drivers are diverting onto local roads with the associated increased risk to pedestrians and other road users.
Our objectives to improve the A14 Junction 55 Copdock Interchange include:
- improving journey times through the junction with increased reliability and facilitate the smooth flow of traffic
- making the road network at the junction itself and nearby roads safer.
- supporting economic growth, especially facilitating reliable access to the Port of Felixstowe and their expansion proposals
- delivering the best environmental design outcome
- providing a more accessible and integrated major road network not just for motorised road traffic but also cyclists, walkers and other users of the network.
- Increasing the local road network’s ability to recover from disruption, including road traffic collisions and other incidents.
