Mark Culver, PE <br />City of Roseville <br />Scenario 3 <br />January 17, 2019 <br />Page 13 <br />Scenario 3 provides the same geometric changes at County Road C2 identified in Scenario 1 but <br />replaces the traffic signal at Lydia Avenue with a grade -separated interchange as shown in Figure 11. <br />The interchange has the benefit of improving flow with a safer pedestrian crossing from east -to - <br />west, but constraints do not allow a full interchange. Therefore, access to Snelling Avenue to/from <br />the north is provided but access to/from the south must be accommodated at County Road C2 <br />utilizing Lincoln Drive or the Snelling Avenue East Service Drive. <br />The construction cost estimate and signal retiming for Scenario 3 is $8,450,000. <br />Figure 11.
