Rossall Sea Defences Pass Halfway Mark
Construction of new sea defenses at Rossall has reached a major milestone as installation of the stepped revetment begins and the project passes the halfway mark.
Two kilometers of defenses from Rossall Hospital to Rossall Point are being replaced in a £63 million coastal defense scheme that will protect 7,500 properties from the risk of flooding.
Around 325,000 tonnes of rock armor are being used to create the base of the defenses, to weather the harsh conditions on this exposed part of the coastline and allow the beach to build up in the area.
Between the rock revetment and the promenade, specially manufactured precast concrete is being used to form a stepped revetment to break the waves.
Each unit, of which there are over 1000 in total, is the weight of around two double decker buses and is placed in position by a vacuum lifter from a crane.
Councillor Roger Berry, Cabinet member with responsibility for sea defenses at Wyre Council, said: “The installation of the first precast concrete stepped revetment units marks significant progress in the construction of the defenses.
“Much of the work for the first two years has been focused on the importation and placement of rock armor to the lower revetment but now we can see the rest of the defenses starting to take shape.”
Of the 2 km being replaced, 850 meters of lower rock revetment and 1185 meters of steel piles are in place, five of eighteen groynes are complete with seven more partly constructed and over 210,000 tonnes of rock have been imported.
