Now that it's been decided that Spaghetti Junction is staying in its current footprint, it needs to be reworked to work. The biggest problems with SJ -- other than our not having an East End Bridge -- are going south to east (one lane ramp off the Kennedy Bridge) and west to north (the I-64/I-71 weave). These are design flaws which 8664 would correct.
A few years ago we created an animation to show people how traffic could flow if we made the junction less complicated. View the SJ animation and use the black button in the lower right-hand corner.
