City of Ramsey 2030 Comprehensive Plan Chapter 6: Transportation forecast AADT and the capacity provided by each facility has been made. The daily capacity calculations were generated by applying Mn/DOT recorded 2007 traffic volumes and 2030 modeled traffic volumes to roadway thresholds generally accepted by Anoka County (see table below) for this comparison and as the basis for assigning a LOS grade. Modeling done for this plan did not alter the thresholds assumed in the Anoka County model. Table 6-3 Daily Capacity by LOS * Area type defined by Metropolitan Council designation of Developing Community for the City of Ramsey. The 2030 forecasts for the base condition (no new Mississippi River bridge) indicate that there will be increased capacity deficiencies on TH 10/169 along its entire length through Ramsey by the year 2030. By 2030, this segment of TH 10/169 performs at LOS F. Other capacity deficiencies anticipated are on CSAH 83 (TH 10 to Alpine Drive), CSAH 56 (TH 10 to Alpine Drive), CSAH 57 (TH 10 to CSAH 116), CSAH 116 (whole route) and TH 47 north of Alpine Drive. These anticipated deficiencies could be minimized if the planned improvements are implemented (i.e. the ultimate build recommendation of widening TH 47 from two lanes to four lanes). Without the planned improvements, TH 47 will operate at LOS F north of Alpine Drive. CSAH 56 between US 10 and CSAH 116 will be expanded to a four lane facility by 2011. CSAH 116 will be widened to a four -lane facility between TH 47 and CSAH 57 in 2011. These improvements should address the congestion on these segments. If TH 10/169 is rebuilt as a four -lane freeway, then there will be sufficient capacity to accommodate the forecast 2030 traffic along its entire length through Ramsey (LOS D or better). If a new Mississippi River bridge is constructed at the location selected by Anoka County and Mn/DOT, the segment of TH 47 between CSAH 116 and CSAH 5 would be relieved of some traffic but would still have insufficient capacity as a two lane undivided arterial to accommodate the projected 2030 traffic. TH 10/169 would still need to be upgraded to a freeway in this scenario to offer adequate capacity. The proposed bridge crossing would lessen minor amounts of traffic through the City of Ramsey. Mostly it would alleviate traffic demand on TH 10/169. These capacity deficiency findings are somewhat more severe than the findings of the 2020 Anoka County Transportation Plan, in part because the forecasts are for 2030. Growth occurring beyond Ramsey will also continue to put pressure on the regional roadway system. D. Roadway System Plan 1. Recommended Policies.
