Quad Gates (for track speed of 110mph or less)

Quad gates have been shown to reduce collisions at-grade crossings by 98 percent.1

The Authority will work with communities along the rail corridors to install safer rail crossings, such as 4 Quadrant Gates, or Quad Gates. Quad gates are designed to block all lanes of traffic on both sides of the track, and to provide a closure delay on the exit side to allow vehicles that may get stuck between the gates to get off the tracks.
