Work has started to repair the pedestrian footbridge at the District Council's Arc Leisure Matlock.
The work to replace metal brackets supporting the decking surface is expected to take around five weeks, with alternative pedestrian access to the leisure centre available from the two car parks via the access road pavement.
Access from disabled parking areas is unaffected by the work.
A District Council spokesperson said:
"We found some deterioration in the metal brackets during a routine inspection and the bridge was closed last week as a precaution. We've taken the decision to replace all of the metal brackets to ensure that this problem will not happen again in the future.
"Although the brackets are relatively small components, the surface of the footbridge needs to be removed to allow access. As a result of this and the specialist access equipment required, the bridge will unfortunately need to be closed during the work.”
Arc Leisure Matlock was opened by the District Council six years ago.
