Mr. Shane Nelson <br />City of Ramsey <br />Page 2 <br />Purpose of Study <br />The purpose of this study is to identify improvements to TH 47 and CSAH 116 in the area of the <br />intersection that will improve access to local businesses and reduce congestion in the area of the <br />intersection. The improvements may include median breaks on CSAH 116 and TH 47, as well as the <br />potential addition of turn lanes. The study will analyze previously identified alternatives, as well as <br />other possible alternatives in order to identify a plan that all affected agencies can support. The agencies <br />involved include MnDOT (TH 47), Anoka County (CSAH 116), and the cities of Anoka and Ramsey. <br />Alternatives that will be considered include: <br />1. Provision for a northbound left -turn from TH 47 into the southwest quadrant of the TH 47 and <br />CSAH 116 intersection with no left -turn out (3/4 intersection) <br />2. Provision for a median break and left -turns from westbound and eastbound CSAH 116 west of TH 47 <br />with no left -turn out <br />3. Provision for a second southbound left -turn lane on TH 47 at CSAH 116 <br />4. Provision of a 3/4 access intersection to local businesses on TH 47 north of CSAH 116 <br />5. Provision of an additional through lane on TH 47 within the limits of the study area <br />6. Review of median widths and the ability to accommodate U-turns on TH 47 and CSAH 116 <br />The intersection of County Road 5 and TH 47 was also identified as a potential contributor to the <br />concerns at CSAH 116 and TH 47 and will be reviewed to determine if modifications to this intersection <br />can address the traffic congestion in this area. <br />Scope of Work <br />The following tasks will be completed as part of this study. <br />1. Data Collection — WSB will collect existing base mapping, previous alternatives, and existing and <br />forecast traffic data. MnDOT and Anoka County will provide traffic counts they have for the <br />CSAH 116 and TH 47 intersection and the County Road 5 and TH 47 Intersection. AM and PM peak <br />hour turning movements will be compiled for the two intersections, as well as for the other access <br />points into the adjacent businesses. We have identified seven locations (four full -access <br />intersections and three partial -access intersections) where data is desired. We have assumed in our <br />cost estimate that Anoka County is available to collect any additional traffic counts that are <br />required. <br />2. Traffic Forecasts — Peak hour turning movement forecasts will be developed for the seven <br />intersections identified above. The peak hour turning movement forecasts will be developed by <br />factoring existing turning movement counts based on the projected growth in ADT between the <br />existing ADT and the forecast 2035 ADT. The projected ADT growth will be based on the forecasting <br />completed for the TH 47 study. <br />3. Traffic Operations Analysis — Synchro/Simtraffic will be used to analyze the traffic operations of the <br />CSAH 116 and TH 47 Intersection, the 142nd and TH 47 Intersection, the CR 5 and TH 47 <br />intersection, and the local business access points for the AM and PM peak hour for the existing and <br />
