Sub-problem 3c: The Southwestern Quadrant

One of the most interesting spots to study in the I-787 interchange is the southwestern quadrant, where the ramps are all non-standard:

bullet

the diverge from Route 7 eastbound

bullet

the split into a collector/distributor road

bullet

the right-hand ramp from Route 7 eastbound to I-787 southbound

bullet

the semi-direct ramp from Route 7 westbound to I-787 southbound

bullet

the merger of these two ramps with each other and with I-787 southbound

There are many issues regarding these ramps, but we will focus on only the connections between Route 7 eastbound and I-787 southbound and Route 7 westbound and I-787 southbound.

Discussion:
Take a few minutes to consider the layout of these ramps. When you are ready, click continue below to proceed.
