Eastern Harbour Crossing
Constructed mainly along the seaward frontage of Kwun Tong Business Area, the bypass was built to alleviate traffic congestion on Kwun Tong Road of Route 7, to which it is parallel. It bridges Eastern Harbour Crossing (Route 2) and Tseung Kwan O Tunnel (Route 7) at its southeastern end with Tate's Cairn Tunnel (Route 2) and Kai Tak Tunnel (Route 5) at its northwestern end, providing a fast connection across eastern New Kowloon.
