DESCRIPTION OF THE CORRIDORThe Shawnee Mission Parkway corridor provides east-west travel movement through seven cities in northeast Johnson County. It also provides a connection to I-35, I-435, K-7 and Rainbow Boulevard (US-169).

Shawnee Mission Parkway is a four lane arterial from the Kansas-Missouri state line to the I-35 interchange. Between the I-35 interchange and Pflumm Road in Shawnee it is a six lane arterial. West of Pflumm Road, the corridor returns to four lanes and is designated as an expressway.

KEY DEVELOPMENT INFORMATIONShawnee Mission Parkway serves as a primary east-west commercial corridor through Johnson County.

The anticipated East Gateway Development, at the intersection of Roe Avenue and Shawnee Mission Parkway in the city of Mission, is expected to be a major future generator of travel along the corridor. In accordance with this development, there is some population and employment growth expected in the area between Metcalf Avenue and Roe Avenue in Mission.

Other places of potential future growth along the corridor include the area between Quivira Road and Nieman Road in Shawnee and just to the east of the I-435 interchange

Shawnee Mission Parkway Corridor

also in Shawnee. Some employment growth is also anticipated at the Shawnee Mission Parkway and I-435 interchange. At the intersection of Shawnee Mission Parkway and K-7 there is also very high population and employment growth projected in the future.

TRAFFICThe Shawnee Mission Parkway corridor currently experiences peak hour congestion from the state line to I-35. Additional congestion is projected for the year 2040 from the state line to Quivira Road and from I-435 to Woodland Road.

OTHER MODESThe Metcalf/Shawnee Mission Parkway corridor has been studied and recently received a TIGER grant to fund transit infrastructure improvements including a transit signal priority system, park-and-ride locations, transit stations and pedestrian improvements. This will include a major transit center in the City of Mission. A ridership forecast projects around 1100 riders per day on the Shawnee Mission Parkway express bus route.

CORRIDOR CONNECTIONSThe Shawnee Mission Parkway corridor interacts with three of the principal north-south highways in the study area. The Shawnee Mission Parkway interchange with I-35 currently experiences significant congestion, which

is projected to continue into the future. There is currently some congestion during the peak period in the area around the I-435 interchange. There is no congestion anticipated at the K-7 interchange. RECOMMENDED STRATEGIESThe continued maintenance and operation of existing roadways and transit services is a critical “baseline” strategy for the Shawnee Mission Parkway corridor.

A variety of strategies were considered to improve current and future traffic operations on the corridor through the year 2040. These strategies are shown in Table 14-24. Strategies that are recommended as part of a corridor package are shaded in blue; strategies that were not recommended during the 2020 to 2040 timeframe are not shaded. Each strategy was assigned an identifier code of a letter and number that are shown on the Shawnee Mission Parkway corridor maps. An “S” indicates a system management strategy, a “D” indicates a demand management strategy, and 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.

System Management StrategiesThese strategies seek to enhance traffic flow and reduce congestion through better management and operation of the existing transportation facilities.

S22: Optimize the traffic signal phasing, timing, and coordination along Shawnee Mission Parkway. This strategy seeks to minimize delays to drivers traveling along this corridor.

Demand Management StrategiesThese strategies address transportation needs by reducing the number of vehicles during the peak travel periods.

D2: Expand transit service - a BRT type service similar to that on Metcalf Avenue is envisioned for Shawnee Mission Parkway. This service would provide all-day service, Saturday, and limited Sunday service. Planning, design and construction for service, stations, signal pre-emption and real-time information would need to be completed.
