The Environment Agency is refurbishing seven access track bridges spanning the Cut-Off Channel.

Work started mid July on bridges from Feltwell, Norfolk in the north to Lakenheath, Suffolk in the south.

The Environment Agency owns the bridges and has a legal responsibility to ensure they are maintained in a safe condition.

The bridges will be strengthened to accommodate current traffic and loading requirements; and to ensure the health & safety of the general public and all bridge users including local farmers and Environment Agency staff who use the bridges as part of their normal daily operations.

Each bridge will need to be closed for approximately 8 weeks while work is carried out to remove existing surfacing, construct reinforced concrete beams along both edges of the bridge, install safety fencing, and resurface. A sign-posted diversion route will be in place at bridges which carry a public right of way.

Contractor Jackson Hyder Ltd is refurbishing the bridges on behalf of the Environment Agency and is expected to complete them by March 2016.

LDM Scanning Ltd worked on the first bridge in July 2015 carrying out the non intrusive concrete scanning survey at Porters Bridge, Feltwell, Suffolk to locate the existing reinforcement & post stressed tendons on the bridge deck and reinforcement on the parapet marking on the structure at the locations where dowels are to be installed as well as a plan prepared showing the locations of reinforcement & tendons surveyed.
