Table 14-26: Western Johnson County North-South Arterial Corridor Strategy Package

CONCEPTUAL ALIGNMENTA corridor for a north-south arterial street was studied as an alternative to a potential outer loop. The Comprehensive Arterial Road Network Plan (CARNP) for Johnson County includes a north-south arterial street. This corridor is shown as the shaded area in the corridor map. The dashed line on the map represents the alignment that was analyzed using the 5-County Travel Demand Model; this alignment is for general study purposes only.

The north end of the corridor is the existing Evening Star Road interchange on K-10 near Eudora. Going south from K-10, the alignment veers to the east and passes through the western side of the former Sunflower Army Ammunition Plant redevelopment property. The corridor then follows portions of Edgerton Road and Sunflower Road to a connection at the recommended new interchange at US-56 and 199th Street between the Cities of Edgerton and Gardner.

KEY DEVELOPMENT INFORMATIONFor trips bound for the west, some of the trucks traveling to and from the new BNSF Intermodal Facility may seek alternatives to using the heavily traveled and urbanized I-35 and I-435 to access K-10. The intermodal facility is expected to generate a total of 7,000 truck trips per day with only approximately two percent traveling to the west. If the former Sunflower Army Ammunition Plant property redevelops as planned, a high volume of traffic will be generated. The potential North-South Arterial would be a major route accessing this property.

TRAFFICTravel demand modeling for this corridor assumed the potential population and employment growth along K-10, in the Sunflower redevelopment site, and near the BNSF Intermodal Facility. The model predicts that the North-South Arterial would carry approximately 13,900 vehicles per day in the year 2040.

OTHER MODESThere are no other modes planned for this corridor.

CORRIDOR CONNECTIONSThe potential North-South Arterial would provide a new connection between K-10 and US-56 in western Johnson County. Both K-10 and US-56 provide east-west connections across the 5-County region.

RECOMMENDED STRATEGYThe recommended strategy was to construct a new 4-lane arterial in western Johnson County. This strategy is shown in Table 14-26. Each strategy is assigned an identifier code of a letter and a number that is shown on the corridor map. A “C” indicates an added capacity strategy.

The table shows how each strategy scored for the criteria used to evaluate each of the 9 Desired Outcomes. Stakeholders determined that the 9 Desired Outcomes should be used in making transportation investment

decisions. The total score for each strategy was determined by multiplying the individual outcome score by a weighting factor that was established by stakeholders for that desired outcome. The total cost is given in year 2020 dollars and includes the construction/ implementation cost and 10 years of maintenance/operation cost. The Benefit Ratio was determined by dividing the Total Score by the Total Cost in $millions.

INCREASED CAPACITY STRATEGIESThese strategies increase the traffic-carrying capacity of a roadway through adding lanes, modifying interchanges, and constructing new roadways.

C16: Construct an improved 4-lane arterial street from K-10 south to US-56. The alignment would begin at the existing K-10 and Evening Star Road interchange and go south through the former Sunflower Army Ammunition site then using Edgerton Road and Sunflower Road to connect to a recommended interchange at US-56 and 199th Street.
