The route starts off Route 3 near Yau Ma Tei, passes through the new Central Kowloon Route and an unnamed submarine tunnel which together leads to the underground of Kai Tak Development Area, junctioning Route 5 on the way. Then the route junctions Kwun Tong Bypass of Route 2 in Kowloon Bay, and runs through Trunk Road T2 to Lam Tin, where it junctions with Route 2 again at the entrance to Eastern Harbour Crossing and runs into another proposed route, Tseung Kwan O - Lam Tin Tunnel to southern Tseung Kwan O.
The route, when completed, is expected to relieve the congestion problem in Kowloon, and will also serve as an alternative route for the existing Tseung Kwan O Tunnel, although still under planning.
