90 METHOD SPEED REDUCTION NOTES Gateway Assemblies Drawing: Saskatchewan Ministry of Highways & Infrastructure Unknown Gateway assemblies use barricade-like signage mounted on roadway side-slopes to increase the visibility of the work zone approach. They are also said to create a sense that the driver is entering a more constrained environment.
