Grade-separated pedestrian and cycling routes often require modest space since they do not typically intersect with the facility (such as a highway) that they cross. However, grade-separated pedestrian crossings with steps introduce accessibility problems. Some crossings have lifts, but these can be time-consuming to use.
A pedestrian separation structure is any structure that removes pedestrians from a roadway, street or railway track. This creates a road junction where vehicles and pedestrians do not interact. This can be considered a type of grade separation structure on the road. These structures can be located either above the roadway or below the roadway.

Pedestrian footbridges and tunnels are also grade-separated. The opposing directions of travel are separated by a central reservation (UK) or median strip (US) generally a few meters to a few dozen meters wide, which may consist of a traffic barrier or a natural barrier like grass. This separation makes controlled-access highways a subset of ...
Work on the $24.7 million RM 620 Roundabout Project began in 2020 and was completed this week. It is intended to improve safety, enhance mobility in west Round Rock.
Proper design of grade-separated interchanges to provide for the movement of traffic between two or more roadways on different levels. More frequent (compared to other road types) construction of tunnels and overpasses, requiring complex equipment and methods of operation.
