The temporary pedestrian and cycle path by the Shelter Hall on the seafront will now be closed for a few days while work to stablise the “very unstable” ground there takes place.
The Shelter Hall at the bottom of West Street is undergoing restoration as part of a project also aimed at strengthening the arches keeping the A259 above it from collapsing.
A council spokesman said: “We’re closing the pathway behind the current Shelter Hall work as a precaution while our contractors carry out heavy piling work to strengthen the seafront arches. The ground and structures there are very unstable and liable to movement.
“We’ll confirm the duration of the closure as soon as we can. It’s likely to be a matter of days. We’re sorry for the inconvenience but this is crucial work to stop the seafront road eventually collapsing.”
In the meantime, pedestrians and cyclists are asked to use nearby pedestrian crossings while the closure is in place. Cyclists will need to dismount.
