The contract contains 22 specific MAEs of which:
■ 9 relate to CCT's access to entry and exit lanes on surface roads (the tunnel portals, meaning the ways to get in and out of the tunnel)
■ 10 restrict the use of road space by general traffic along the central Druitt, Park and William Street corridor
■ 2 provide the CCT with access to the Cahill Expressway and the Domain Tunnel at the expense of local roads
■ 1 restricts the use of road space by general traffic on Kings Cross Road.
In addition an MAE may arise if the CCT is adversely affected by changes to the project's conditions of approval. Exhibit 4.9 summarises the road changes by category and location.
