CASS COUNTY ROADWAY 18 EXTENSION STUDY – CASS COUNTY, ND 22 between CR 18 interchange and the City of Kindred is shown in Table 7. As shown in Table 7, the I-29 and ND 46 route has a shorter travel time and is a paved surface and is expected to attract more traffic than 52nd Street SE. Once future traffic volumes are determined for each alternative, the forecasts were reviewed for balance forecasted traffic volumes. Table 7. Travel Times Between CR 18 Interchange and City of Kindred 4.4.2 ROADWAY SECTION ALTERNATIVES For the traffic forecasting, three general alternatives were considered for the improved 52nd Street SE; No-Build (Existing) Section, Aggregate County Typical Section, Paved County Typical Section. The design criteria for the roadway alternatives was not a consideration as the roadway width, ditch foreslopes, etc. would at least meet the County’s minimum criteria and not have a significant impact on travelers choosing a route. The speed limit for 52nd Street SE for each of the three alternatives was kept at 55 miles per hour with 0.5 miles at 25 miles per hour. The paved roadway surface was assumed to be attract more traffic volume due to the consistent surface (i.e. no impacts from wet weather, aggregate washboarding, etc.) for the travelling public.  No-Build Alternative  Aggregate Surface Alternative  Paved Surface Alternative 4.4.3 TRAFFIC FORECASTS The traffic forecasts for all three roadway alternatives was completed for the future years 2025 and 2045 based on the average of the spring and fall 2018 traffic counts. The traffic forecasts are included in Figure 12 and Figure 13 for 52nd Street SE. It is expected that some of the additional traffic volume on 52nd Street SE would be due to vehicles using an improved roadway section from County Road 15 and 17.
