Spack Consulting 6 of 6 1715` Ave & Twin Lakes Rd Traffic Analysis Conclusions and Recommendations Based upon the information and analysis presented in this report, the following is recommended: • Construct the new Twin Lakes Road corridor that will extend south from the railroad crossing to a new access with Highway 169 as a three -lane roadway (one through lane in each direction with a center left turn lane) with right turn lanes provided at major intersections. • Provide side - street stop control at the new intersection of 171" Avenue and Twin Lakes Road, with the stop signs placed on 171" Avenue. Traffic on Twin Lakes Road should be able to proceed without stopping to reach the new access with Highway 169. • Other intersections on Twin Lakes Road to the south of the 171" Avenue intersection should also have side - street stop sign control (Twin Lakes Road traffic allowed to proceed without stopping). However, these intersections are potential candidates for signalization and should be monitored into the future. • Due to the high amount of truck traffic, including over -sized trucks, wide lanes and intersection corner radii should be provided. • Depending upon the confidence of the future traffic projections and growth assumptions, the corridor right -of -way could be preserved to allow for future expansion or reduced with some land returned to surrounding private owners. • Efforts should be made to relocate or limit the private driveways on Twin Lakes Road near the railroad crossing, if it can safely be accomplished without significant impacts to the businesses. • The existing and future 171" Avenue corridor and Twin Lakes Road corridor (north of the railroad crossing) both have existing and expected future traffic volumes within the capacity of a three -lane roadway section and could be restriped.
