1. Gantry
A gantry is a structure that spans above a road and supports traffic signs, lane-control signals, variable-message signs, cameras or other traffic-management equipment. Gantries are commonly used on motorways and other multi-lane roads where signs need to be positioned directly above individual traffic lanes.
Signs or signals mounted on a gantry may apply to specific lanes rather than the entire carriageway. Drivers should therefore pay attention to the position of each sign or signal and follow the instructions applying to their lane.
What is a road gantry?
A gantry is an overhead structure spanning a road that supports traffic signs, signals or other traffic-management equipment.
Why are gantries used?
Gantries allow signs and signals to be placed directly above traffic lanes, making lane-specific directions, restrictions and traffic information easier to see.
Can different signs on the same gantry apply to different lanes?
Yes. Where signs or lane-control signals are positioned above individual lanes, each indication may apply only to the lane directly below it.
