St. Anthony 2040 Comprehensive Plan Chapter 6: Transportation <br /> <br />74 <br /> <br />Existing Capacity Problems on Arterial Roads <br />At the planning level, capacity problems are identified by comparing the existing <br />number of lanes with current traffic volumes. FIGURE 6-7 and FIGURE 6-5 illustrate the <br />existing number of lanes on arterial roadways within the City. FIGURE 6-6 illustrates <br />existing traffic volumes on Principal Arterial, A-Minor Arterials and other significant <br />roadways within the City. <br />As shown in the table, I-35W is the only arterial roadway located within or adjacent <br />to the City that has more than four lanes. All other arterial roadways have four or <br />fewer lanes. Two arterial roadways transition between the number of lanes. In <br />some locations, these roadways have two lanes, four lanes, or three lanes (one <br />travel lane in each direction with a center two-way left-turn lane). All St. Anthony <br />Village existing traffic volumes are below or within the planning level capacity <br />thresholds shown in FIGURE 6-4, however, some congestion does occur along some <br />primary routes, such as Silver Lake Road, due to operational constraints at <br />intersections. <br />
