With the current geometry of the interchange, in order <br />to access eastbound I-94 from southbound Highway 101, southbound traveling vehicles need to be <br />in the right -most lane. This results in poor southbound lane utilization north of the interchange and <br />lengthy queues that effect the intersection of Highway 101 and South Diamond Lake Road. <br />Figure 39 and Figure 40 show that under the no -build forecast, AM and PM peak hour intersection <br />delay is expected to more than double on South Diamond Lake Road. This delay is largely resolved <br />by reconfiguring the I-94/Highway 101 interchange as in Concepts 1 and 2. A new river crossing <br />does not solve the poor lane utilization issues present with the existing interchange configuration, <br />but it still does improve delay at South Diamond Lake Road, especially during the AM peak. <br />Figure 39: I-94/Hwy 101 Intersection Delay; AM Peak Hour <br />Existing Conditions 37 11 <br />2040 No Build - Traditional 360 <br />2040 Concept 1 - Traditional Mai954 24 <br />2040 Concept 2 -Traditional 1.1 28 <br />2040 Concept 314 - Traditional 31 16 <br />IM 38 11 <br />• D'=rror,d L.=ke R <br />• North Ran <br />• South Ramp <br />0 50 100 150 200 250 300 350 400 <br />I ntersection Delay (sec) <br />Figure 40: I-94/Hwy 101 Intersection Delay; PM Peak moue <br />Existing Conditions 26 ill <br />2040 No Build - Traditional 15 <br />2040 Concept 1 - Traditional <br />2040 Concept 2 - Traditional <br />2040 Concept 314 - Traditional <br />34 28 <br />his 17 <br />14 <br />• Diamond Lake Rai <br />• North Ramp <br />▪ South Ramp <br />0 50 100 150 200 250 300 350 400 <br />Intersection Delay (sec) <br />Northwest Metro Mississippi River Crossing Feasibility Analysis <br />
