intersections is summarized below. • The Highway 96/Highway 10 intersection under existing conditions functions at a Level Of Service F during the PM Peak Hour. Separate analysis of the Highway 96/Gateway Boulevard intersection indicates that the intersection functions at an acceptable level of service today,however the intersection will require a signal in the near future to accommodate the development of the Gateway Business Park. The existing accesses along Highway 10 north of Highway 96 currently do not function as a single intersection and therefore were not evaluated in the existing condition. FORECAST SCENARIOS Scenario 1: At-Grade Intersections at Highway 10 & Highway 96; Gateway Boulevard & Highway 96; Gateway Boulevard & Highway 10 Traffic Movement/Access Provided This scenario would maintain full access in all directions for traffic on Highway 96 as well as • traffic entering the City on Trunk Highway 10. Access to the redeveloped TCAAP site and the redeveloped Highway 10/96 Triangle would be through Hamline Avenue, Snelling Avenue, Gateway Boulevard, County Road H2 and County Road I. All future scenarios assume that one at grade intersection(or crossing)would replace the multiple existing entrances onto TH 10 north of Highway 96. The proposed intersection of TH 10 and Highway 96 would include dual left-turn lanes on the southbound TH 10 approach to accommodate 336 peak hour left turns. Single left turn lanes would be provided on all other legs. Free right turn lanes would be provided for TH 10 traffic onto Highway 96 from both north and south approaches. Dual left turn lanes would be required for eastbound Highway 96 to northbound Gateway Boulevard to accommodate 443 peak hour left turns. The analysis indicates a high number of right turn movements for southbound Gateway Boulevard to westbound Highway 96 which may require free right turn access or multiple turn lanes. Dual left turn lanes would be required for southbound Highway 10 to eastbound Gateway Boulevard to accommodate 790 peak hour left turns. Old Highway 10 would be realigned to run parallel between Highway 96 and Round Lake connecting to Gateway Boulevard west of Round Lake. The relocation of the Old Highway 10 access is necessary to provide the minimum desirable separation between full access intersections along Highway 96. This scenario requires that the alignment of Highway 96 be shifted north from its current location in order to accommodate the frontage road without any additional impacts to Round Lake. • 6
