Memorandum <br />May 16, 2006 <br />Page 2 of 15 <br />Historical Traffic Volumes <br />The Silver Lake Road area in St. Anthony has had a large fluctuation in traffic volumes over <br />the last 25 years. Local redevelopment and increased commuter traffic to/from the <br />Minneapolis area has caused modest growth on Silver Lake Road over the last ten years. <br />Mn/DOT historical traffic counts, Table 1, shows an average annual growth rate of about 3.5 <br />percent on Silver Lake Road at 39th Ave NE over the last ten years. This growth rate is high <br />for similar roadways in Hennepin and Ramsey Counties, but not unexpected, due to the <br />redevelopment of the old Apache Mall site. Hennepin and Ramsey Counties have seen an <br />average of 1 percent to 1.5 percent growth per year on similar roadways within the counties. <br />HistoricalTable 1.
