City of Arden Hills – 2040 Comprehensive Plan <br /> <br /> <br />Approved:, XXXX <br />11-3 <br />Table 11.1 – Planning-Level Roadway Capacity <br />Facility Type <br />Daily Two-Way Volume <br />Lower <br />Threshold <br />Higher <br />Threshold <br />Arterials <br /> <br /> <br /> <br />Two-lane undivided 10,000 12,000 <br />Two-lane divided or three-lane <br />undivided 15,000 17,000 <br />Four-lane undivided 18,000 22,000 <br />Four-lane divided or five-lane undivided 28,000 32,000 <br />Freeways Four-lane freeway 60,000 80,000 <br />Six-lane freeway 90,000 120,000 <br />Eight-lane freeway or higher Calculated on a segment <br />by segment basis <br /> <br />At the planning level, capacity problems are identified by comparing the existing <br />number of lanes with current traffic volumes. Table 11.2 and Figure 11.1 illustrate <br />the existing number of lanes on arterial roadways within the city. Figure 11.2 <br />illustrates existing traffic volumes on Principal Arterial, A-Minor Arterial and other <br />significant roadways within the city. <br /> <br />Congestion analysis shows I-35W and I-694 as the roadways with significant <br />congestion. The rest of the existing transportation system throughout Arden Hills <br />is primarily periodically congested, with areas that are near congested. Of <br />primary concern to the City of Arden Hills is the congestion on TH 51/Hamline <br />Avenue, south of I-694 and the county roadways at the interchanges with I-35W. <br />This indicates that the congestion on I-35W is impacting the county roadways <br />that have access to it. As I-35W becomes more congested, more traffic will likely <br />use TH 51 or other adjacent minor arterials as an alternate route, which may also <br />become congested. <br /> Draft 03/07/2018
