Steel in the shape of Y columns has now been installed close to the existing stand to cantilever the structure over and create a space underneath. This prevents weight being transferred to the existing stand and forms the void that will become an extended lower concourse area.This work involves the precise alignment of steel bolts cast into concrete, which are secured to carefully prepared base plates that are set to an exact level. Twelve Y columns have been installed.The redevelopment of the Anfield Road Stand, which will add 7,000 seats to the overall stadium capacity, began in late September and is anticipated to be ready for the 2023-24 season.Take a look at the current phase of the construction in the video above and pictures below.
