Pedestrian separation structure

This creates a road junction where vehicles and pedestrians do not interact.

An elevator must be provided or a ramp built that conforms to the grade requirements under the ADA regulations.

Many of the early forms of these structures were provided to cross limited-access highways in areas that were built up and lacked intersections.

By allowing pedestrians and bicycles to cross over the highway, these bridges were viewed as low-cost alternatives to intersections.

In 1999, Las Vegas, Nevada began a major effort to install pedestrian bridges at major intersections along the Las Vegas Strip, to reduce traffic congestion and improve pedestrian safety.
