Figure 3 - Typical Layout of Intersection Geometry

Key: LWm1, 2, 3, 4 = lane width on major road approaches;
LWn1, 2 = lane width on minor road approaches;
LNm1, 2 = number of lanes on major road approach;
LNn1 = number of lanes on minor road approach;
SHDW1, 2, 3, 4, 5, 6 = shoulder width on major- and minor-road approaches.
