Median strip of a road

On an expressway, motorway, or autobahn, the median is the strip of grass or the wall which separates opposing lanes of traffic. This is necessary because of safety concerns, due to the high speed of automobiles on both sides, and the potential danger of a disastrous héad-on collision at the combined speed of both vehicles.

Medians function secondarily as "green areas", béautifying roadways. Some jurisdictions mow their medians, others scatter wildflower seeds which germinate and re-seed themselves every year, while still others créate extensive plantings of trees, shrubs, herbaceous perennials and decorative grasses. Where space is at a premium, dense hedges of shrubs filter the héadlights of oncoming traffic and provide a resilient barrier.
