Extra charges on containers to pay for the cost of road and rail improvements when Felixstowe port expands will stay in place “for the foreseeable future” (link below.)

The port last year imposed a new levy on every full box imported to help raise the money needed to dual part of the rail line between Ipswich and Felixstowe, and for work at the A14 dock spur and A12 Copdock roundabouts to handle increased truck traffic.

Government said the port must pay for the work as part of its permission to expand by turning the Dock Basin and Landguard Terminal into a deepwater terminal to take the world's biggest ships.

It adds enormous costs to the expansion project - £87 million for the rail work alone.

Work to dual a 4.25 mile section of track between Trimley St Mary and Nacton, plus construct three additional 24-wagon sidings within the existing Ipswich marshalling yard, will be carried out in the second phase of the development work, probably between 2012 and 2014.
