SUPER-sized convoys will deliver the building blocks for the biggest viaduct to be built in West Sussex.

Police will escort the load of 179 beams for the Felpham Relief Road on Mondays and Wednesdays until mid-November with each convoy taking up to 30 minutes to arrive at the construction site once they leave the A27.

The 3km relief road will feature a 0.5km viaduct that rises 8m above the Lidsey Rife, the Barnham to Bognor Regis Rail Line and Bognor Regis Flood Plain. It is expected to open next year.
