Problem 3: Basic Freeway Sections

Exhibit 4-45 shows a view of Location E looking north taken from a location that is about halfway through the weaving section at Location E. The sign to Route 7 west can be seen at the right-hand edge of the picture. The bridge immediately overhead is Route 7. The bridge in the background is the semi-direct ramp leading from Route 7 westbound to I-787 southbound. The merge sign in the distance at the left-hand edge of the picture is associated with the location where the right-hand ramp from Route 7 west merges with I-787 north.

Exhibit 4-46 shows a view looking east at Location L. The left-hand lane is the auxiliary lane that goes from Location F on the western end to a point just beyond Location L. To the left in the picture you can see the place where the auxiliary lane rejoins Route 7 east. The right-hand lane is simultaneously the end of the south-to-east loop ramp going from I-787 south to Route 7 east and the beginning of the east-to-north loop ramp going from Route 7 east to I-787 north. You can see the start of the east-to-north loop ramp in the right-hand side of the picture. In the distance, you can see the spot where the right-hand ramp from I-787 to Route 7 joins Route 7, which is also the start of the weaving section at Location B.
