I '. Highway to/Highway 96 Interchange Layouts I F our layouts for the Highway 10/Highway 96 Interchange were reviewed in order to make an accurate comparison between different levels of access at the intersection and their associated I benefits and costs. The traffic model assumed the Highway 96/Highway 10 intersection either had full at-grade access in all directions (scenario 1) or a separated grade crossing with no access between the two roadways (scenarios 2 and 3). In this section, we will evaluate four layouts for I the intersection; At-Grade Signalized, Separated Grade-North Access, and Separated Grade- North and South Access and Separated Grade-No Access. I In order to provide a minimum level of access for properties in the Highway 96/Highway 10 Triangle and existing TCAAP entrances, access between Highway 96 and Highway 10 to the north must be maintained. Access between these districts and points south and west via I Interstate 35W must utilize Highway 96 and Highway 10. At the time of redevelopment ofthe Highway 96/10 Triangle and TCAAP, the benefits of providing access between Highway 96 and Highway 10 become less apparent. I Layout #1: At -Grade Signalized I The proposed intersection configuration for this layout is similar to the existing configuration with the exception of free right turn lanes for westbound Highway 96 to northbound Highway 10 traffic and eastbound Highway 96 to southbound Highway 10 traffic. In the interests of . maximizing the efficiency and safety of Highway 96, the intersection of Old Highway 10 and Highway 96 would be relocated to avoid conflict with the Highway 10 intersection. I Old Highway 10 would be realigned to run parallel between Highway 96 and Round Lake connecting to Gateway Boulevard west of Round Lake. In order to provide space for Old Highway 10 without impacting Round Lake, the alignment of Highway 96 be shifted north from I its current location. Shifting the Highway 96 alignment north will cause additional impacts to the Arden Manor Mobile Home Park. I Layout #2: Separated Grade-North Access I The proposed intersection configuration for this layout includes bridging Highway 10 over Highway 96 with access ramps from Highway 96 to Highway 10 northbound and from Highway 10 southbound to Highway 96. The general grade of Highway 10 would remain close to its I existing grade while Highway 96 would be reconstructed to pass approximately 23 feet below Highway 10. No access would be provided from Highway 96 to Highway 10 southbound or from Highway 10 northbound to Highway 96. Old Highway 10 would be realigned slightly in I order to intersect Highway 96 opposite the Highway 10 off ramp. The ramp intersection west of the Highway 10 bridge would be signalized to provide for the large number of vehicles turning left onto Highway 96 and left turning vehicles from Highway 96 to Old Highway 10. It is not I anticipated that the ramp intersection east of Highway 96 would warrant a signal at this time. f 10 I
