Median Crossing Upgrade

A median crossing is a section of roadway provided between a divided carriageway to allow cross median movements and U-turns. A median crossing upgrade may provide deceleration and acceleration lanes reducing the risk of rear-end and opposing vehicle type crashes.

A wide shoulder or deceleration lane will allow slowing vehicles to manoeuvre out of the through lane. An acceleration lane will allow vehicles to merge with through traffic on the roadway.
