R3C15

The slip road from Tuen Mun Highway to Tai Lam Tunnel was constructed using two different methods. The section near the approach viaduct utilised a balanced cantilever method due to its larger span. The farther section, as seen in the photo here, is constructed of precast beams with in situ reinforced concrete deck. To overcome the problem of access, a temporary mini-rail was erected on the deck of the slip road.
