A 200 metre stretch of the sea wall along Jersey's St Aubin's Bay is being raised to stop people falling from the promenade.
30 centimetres of granite will be added to the section of the wall along the seafront between La Haule slipway and the toilet block to the east.
The government says it is the only significant stretch without a raised wall, barrier or railing separating the cycle track and pedestrian path from the beach below.
The drop is between 3-4 metres and concrete foundations sometimes are sometimes exposed above the sand.
Officials say the masonry 'upstand' was decided upon following an independent safety audit.
“The top of the existing sea wall is currently flush with the promenade paving. This new wall will clearly improve safety for pedestrians and those who cycle along this popular route.
The use of Jersey granite, and the relatively low height of the wall means it will be visually non-intrusive and will be very much in keeping with the structures that are already in place further towards the village.” - Assistant Infrastructure Minister Deputy Steve Ahier.
Work will start next week (24 October) and is expected to take 10 weeks,
If will cost an estimated £90,000.
The promenade and cycle track will remain open throughout.
