Expert crews have discovered that some additional essential works need to be undertaken meaning that the road will have to be closed from next Monday.
The essential works to replace a deteriorated small span bridge underneath the A153 were originally scheduled to happen from April 11 to June 24 - with traffic management meaning that the road would remain open whilst the works happened.
But as the works have progressed, the expert crew undertaking the job has discovered an area in the middle of the bridge that needs further extensive repair. Because this unforeseen extra work is in the middle of the bridge itself, the road will have to undergo a full closure.
The road will now be closed entirely from 06.00 on Monday June 13 until 17.00 on Friday June 24.
The diversion route will run through Woodhall Spa and Martin before returning to the A153.
Karen Cassar, assistant director of highways said: “Unfortunately, there is no way for us to avoid further disruption to traffic around these newly-discovered essential works on the A153.
“Because of the position of the area that needs extra repair we will have to close the road entirely for 11 days. We have looked at every alternative to doing this but, in this instance, we have no safe alternative available.
“As always, we have to consider the safety of the road users and work crews as our main priority so the closure will happen to ensure everyone involved is as safe as possible whilst the work is in progress. It’s unfortunate and the discovery of this extra repair need will cause some disruption which we apologise for – but in this case it can’t be avoided despite our best efforts.
“The bridge is in critical need of this rebuild. We would like to thank everyone effected by this latest addition to work for their continued patience whilst we get the task done.”
