A continuous flow intersection for accommodating traffic from a plurality of road surfaces includes a first road surface for traffic traveling in a first direction. A second road surface is provided for traffic traveling in a direction opposite to the first direction. A third road surface is provided for traffic traveling in a direction intersecting the first and second road surfaces. A fourth road surface is provided for traffic traveling in a direction opposite to the traffic traveling on the third road surface. The first and second road surfaces intersect the third and fourth road surfaces and are disposed at a first elevation distinct relative to the third and fourth road surfaces in an area adjacent to the intersection. At least a first road surface left turn lane is disposed along the first road surface at a point displaced a predetermined distance from the intersection. The first road surface left turn lane diverts traffic from the first road surface to cross the second road surface and to continue traveling in a direction opposite to the second road surface in an area displaced laterally from the first road surface. The first road surface left turn lane traverses the intersection at the first elevation distinct from the third and fourth road surfaces and enables traffic to turn left without stopping and to merge from the right with traffic traveling along the fourth road surface.
