Preliminary Preferred Alternative: Alternative 1
(Click to enlarge)
Alternative 1 - the Diamond Interchange - grade-separates 236th Street over U.S. 31 in a tight
diamond configuration. The ramp terminals are single-lane roundabouts.
Access from 241st Street to U.S. 31 will be removed, and a cul-de-sac will provide turnaround access
for properties along 241st Street.
Alternative 1 - By the Numbers
|U.S. 31/236th St. level of service||A||Number of residential impacts||24|
|Percent reduction in future crashes||23.4%||Acres of wetland impacts||0.45|
|Acres of new right of way||122.0||Acres of floodplain impacts||11.5|
|Number of parcels impacted||41||Linear feet of stream impacts||1,400|
|Number of commercial impacts||2||Total project costs (millions)||$24.88|
