A road in Chesterfield town centre will be closed for most of Sunday while a survey is carried out on a footbridge across it.
Chesterfield Borough Council said it needed to remove brackets holding large civic crests to the side of the bridge spanning New Beetwell Street because they had become damaged.
The authority said the crests would be returned at a later date which was dependent on the survey and their condition.
The road will be closed between 08:00 BST and 18:00 with traffic diverted.
