Six sets of moulds will be delivered to Bay State Precast LLC for the 3.84km long Anacostia River Tunnel project in Washington DC. Five sets of moulds will be supplied to the Rennes Line B project for use on a 7.5km long tunnel section. Each ring is composed of five standard and two key segments with an exterior diameter of 7620mm a thickness of 305mm and a width of 1829mm.

The segments will be manufactured in the Bay State Precast LLC factory located at Brandywine, near Washington DC.
