The proposed TKO-LT Tunnel runs beneath the At Tseung Kwan O, the TKO-LT Tunnel in a straight alignment with a branch tunnel for direct connection to 6 7 links to the CBL and Po Yap Road via the the . Tseung Kwan O Interchange. At Kwun Tong side, the tunnel connects to the Lam Tin Interchange The proposed CBL stretches across (next to the toll plaza of the Eastern Harbour Crossing), which links from the TKO-LT Tunnel to Wan the TKO-LT Tunnel to the Trunk Road T2, Eastern Harbour Crossing Po Road near Area 86 of Tseung Kwan and local road network of Kwun Tong. The main carriageway of the O at the east bank. The feature bridge Interchange is around 20m below the existing ground level. of the CBL adopts the “Eternity Arch” configuration with a main span of 200m.

To the west of the Lam Tin Interchange, the tunnel is embedded in Shun Road Po bedrock running beneath the Village.
