屯門公路
The road infrastructure of the town to other areas of Hong Kong relies on Tuen Mun Road and Castle Peak Road, as well as roads to northern Yuen Long District. Until the opening of the West Rail in 2003, local residents suffered from traffic congestion on Tuen Mun Road and Castle Peak Road. However, as of 2019, the railway line also reached its capacity and the government had planned new road to connect the town to the CBD via Lantau Tomorrow Vision. Tuen Mun–Chek Lap Kok Link is under construction.
