<br />. <br /> <br />TH 10 "DIAGONAL" SENSITIVITY TESTS <br /> <br />The segment ofTH 10 between I-35W and 1-694 (TH 10 "Diagonal) is an expressway- <br />type facility with four lanes, limited access and a 60 MPH speed limit. 2025 Forecasts <br />estimate that approximately 28,000 of the 52,000 vehicles per day on the facility will be <br />regional trips that use the entire TH 10 segment. <br /> <br />Two sensitivity tests were conducted to determine the effect of reducing the regional <br />significance of the TH 10 Diagonal. The first test assumed that the north-end connection <br />between TH 10 and CR lOin Mounds View was eliminated. As shown in Figure 13, <br />volumes would be reduced from 52,000-55,000 to 38,000 to 42,000 (the approximately <br />current ADT). A second test eliminated the connection between 1-35W and TH 10. This <br />test showed a more substantial reduction in traffic to approximately 33,000 ADT. It is <br />observed that demand on the TH 10 Diagonal consisted of three components <br />(TCAAP/CSAH 96 area traffic, CR 10 traffic and TH 10 through-traffic. As the CR 10 <br />and TH 10 connections were eliminated, an increase occurred in local (TCAAP/CSAH 96 <br />area) traffic. In addition, some of the TH 10 through-traffic diverted to the County Road <br />H interchange, causing congestion at that intersection. <br /> <br />. <br /> <br />60000 <br />50000 <br />40000 <br />l- <br />e 30000 <br /><( <br />20000 <br />10000 <br />o <br /> <br />. <br /> <br />Figure 14 <br />TH 10 "Diagonal" ADTwith Diversion Options <br /> <br /> <br />I!il Existing <br />..
