Definition
A dual carriageway is a road with two separate lanes for traffic flowing in opposite directions, divided by a central reservation. Think of it as a highway cut in half, ensuring smoother and safer travel. It's similar to two one-way streets side-by-side. The divider prevents head-on collisions, which is super important.π¦ Dual carriageways often have higher speed limits. They facilitate efficient transportation between cities and towns. Itβs a key part of modern road infrastructure.
