屯門公路
Since the road was opened, there have been various improvements carried out to meet the increasing traffic demand, such as the addition of uphill crawler lanes (Tsuen Wan Bound) at Sam Shing Hui, So Kwun Wat, Tai Lam Chung and Ting Kau. The Highways Department has plans to carry out extensive reconstruction works on Tuen Mun Road that will include widening traffic lanes, improving horizontal curvatures and sightlines, and the installation of noise barriers. These works commenced in October 2008 and completed at the end of 2015.
