Why would I use the A37 between Coleraine and the Limavady area?

The A37 Coleraine Mountain corridor offers an inland road connection in the Coleraine–Limavady area.

TrafficWatchNI explicitly lists a camera at A37 Coleraine Mountain, which is useful for checking local road conditions. It is a different experience from the A2 route closer to the coast. For winter or poor-visibility journeys, look at official traffic information and road signs before choosing an upland road simply because it appears shorter on a map.
