Marc Culver, PE City of Roseville Fairview Avenue and Lydia Avenue February 12, 2015 Page 22 • The operational issues under Scenario 2 are a result of northbound queues from the County Road D and Fairview Avenue/New Brighton Road intersection extending through Lydia Avenue. With the recommended traffic control and turn lane improvements at the Fairview Avenue/New Brighton Road intersection, the Fairview Avenue/Lydia Avenue intersection is expected to operate at an acceptable level of service. o The extension of Twin Lakes Parkway (Scenario 3) provides an alternative route to/from I -35W, which will reduce the number of vehicles that make a northbound left -turn at the County Road D and Fairview Avenue/New Brighton Road intersection. While northbound queues will be significant under Scenario 3, the queues are not expected to effect operations at the Fairview Avenue/Lydia Avenue intersection. • Consider expanding Fairview Avenue to a three -lane facility north of County Road C2 to improve mobility and safety along the corridor. • This intersection should be monitored under future conditions. If operational issues occur consider installation of a traffic signal or roundabout. Snelling Avenue Between County Road C and Lydia Avenue) • Snelling Avenue is assumed as a six -lane facility under year 2030 conditions. This is due to the existing conditions operations analysis. • Modifications are necessary to the at -grade intersections along Snelling Avenue or additional capacity is needed along the Snelling Avenue corridor to mitigate the capacity issues that are observed. If this does not occur it is anticipated that traffic will divert to other routes, including regionally, subregionally, and locally. Other Considerations Improvements to the Snelling Avenue/Lydia Avenue and Snelling Avenue/County Road C2 intersections were mentioned in association with the lack of capacity on Snelling Avenue (i.e., eastbound dual left -turn lanes). Further, with the completion of Twin Lakes Parkway between Prior Avenue and Fairview Avenue additional wayfinding, or trail blazing, can be implemented to encourage travelers destined for Snelling Avenue to use Terrace Drive as their route via Lincoln Drive. This will minimize the number of vehicles that use Twin Lakes Parkway to Lydia Avenue for similar trips. Additional intersection modifications may be necessary at the Terrace Drive/ Lincoln Drive and Snelling Avenue/County Road C2 intersections.
