4. ParcIo "A" with four ramps and NW and SE loops a. Plus 1. Addition ofloop adds capacity II. Conventional layout iii. Could have two single lane entrances rather than a two lane entrance iv. Greater spacing between ramp intersections v. Two phase signals at ramp intersections VI. Westbound CSAH 14 traffic entering either northbound or southbound 1-35E can bypass signals with C-D road vii. Requires less right-of-way in northeast quadrant, uses existing R/W in southeast quadrant Vlll. Could make connections to southwest quadrant easier b. Minus i. Northbound exit ramp will need two lane design ii. Wide bridge 5. ParcIo "B" does not fit site very well and has no traffic benefits 6. Single point a. Plus 1. Compact, saves R/W ii. One signal iii. Shortest travel paths b. Minus i. Requires both south ramps to have two lanes ii. Has less reserve capacity than alternatives with northwest loop iii. Right turn onto eastbound CSAH 14 needs to have two lanes and be controlled by signal to avoid weaving, difficult to do with SPill design iv. Right turn onto southbound 1-35E will also need to be a double right v. Southbound right turn a west ramp will need to be signal controlled to avoid weaving VI. Expensive bridge and retaining walls vii. Makes access to southwest quadrant more difficult 7. Super Diamond a. Plus i. Standard design ii. Saves right-of way in northeast and northwest quadrants b. Minus i. Requires south ramps have two lanes ii. Has less reserve capacity at west ramp iii. Makes access to southwest quadrant more difficult 8. Folded "A!B" - Four ramps and loops in southwest and southeast quadrants- Does not fit site very well and has no traffic benefits 9. Folded "BfA" a. Plus
