I ~ Summary This report has presented the results of various analyses performed around the intersection of Highway 96 and Highway lOin order to provide the Council with the information necessary to I select the best fit design of the intersection for Arden Hills. The traffic analyses indicates that the current intersection functions poorly at PM Peak Hours and will continue to decline unless the intersection is grade separated or Highway 10 is expanded to six through lanes. The I traffic model also indicated that a key access point to a redeveloped TCAAP site would need to be located along Highway 10 between Highway 96 and Interstate 35W. The Highway 96 and Highway 10 intersection is limited in the role it can play relative to future. access to the TCAAP I site. Four basic alternative layouts were considered for the Highway 10 and Highway 961nterchange. I All four are constructab1e but have widely varying implications relative to cost, private property, safety, access and adaptability for the future. Layout #1 maintains the full access at-grade intersection and extends Old Highway 10 across Round Lake to Gateway Boulevard. Layout #2 I and layout #3 provide improvement to traffic operations for today and into the future while providing access for businesses and residents in the Highway 96/10 Triangle and the TCAAP site as well as other City residents. Layout #4 represents a possible future condition where the I north access ramps have been removed to allow for a new full access interchange on Highway 10 serving a redeveloped TCAAP site and Highway 96/1 0 Triangle. Layout #4 could be constructed today but would pose serious access hardships on the Highway 96/1 0 Triangle . properties and TCAAP operations. Budget cost estimates and property acquisition estimates have been provided to assist with I comparing the relative merits of the alternatives. Several other considerations have been discussed as well including pedestrian access, implications to the alignment of gateway boulevard, gateway business district access and storm drainage which are affected greatly by the I various alternatives.
