Modifications to intersections would be required as follows to mitigate <br />traffic impacts: <br /> <br />County Road D at Cleveland A venue <br />This intersection would require the addition of an exclusive northbound left-turn lane. Although <br />the majority of traffic to 1-35W would use the Twin Lakes Parkway, some will divert to the <br />lower-volume County Road D interchange. <br /> <br />County Road D at Fairview <br />This intersection would require signalization and the reconstruction of the intersection to a four- <br />legged intersection (by combining the New Brighton Boulevard and Lake Johanna Boulevard <br />approaches). This intersection is currently an all-way stop and operates at capacity in the peak <br />hour. Conversion of the roadway to a signalized intersection was reviewed, but the traffic flows <br />and required signal phasing also resulted in unacceptable levels of service. Because the <br />intersection is currently at capacity, the condition would not be alleviated by reduced <br />development in the AUAR study area. <br /> <br />Twin Lakes Parkway at Cleveland Avenue <br />This intersection would add an east leg to the eXlstmg intersection with the approaches <br />configured as shown in Figure 5.and wous could be constructed to the required geometry as <br />discussed in the detailed traffic study. This intersection would include eliminating the loop from <br />northbound 1-35W exist ramp to Cleveland Avenue to westbound County Road C. <br /> <br />Twin Lakes AUAR <br />Traffic, Air and Noise Analysis <br /> <br />-21- <br /> <br />8RF Consulting Group, Inc. <br />May 3, 2001 <br />
