crawler lane การใช้

Crawler lanes are provided for heavy vehicles between Oteha Valley Road and Greville Road.
On major routes, such as motorways in the UK, the climbing lane is also referred to as a "'crawler lane " '.
A variation that has become common with newer roads and more recent widening schemes is to add an additional " fast " ( passing ) lane for the stretch which otherwise would have had a crawler lane.
This included potentially a suggestion of re-diverting SH8 up the east side of the Clutha River to Millers Flat, general road easements / realignments at old level crossings and the installation of crawler lanes for heavy truck vehicles.
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.
