Straddling bus

A straddling bus is a special kind of bus that is like a bridge over the road. It has two parts, like two bridges on either side. One part is at the normal height of the road, and the other part is higher than the road. Cars can drive underneath the higher part, and buses and pedestrians can use the higher part to cross over the road. It's like a bridge but right on the road, so it doesn't take up extra space.
