When the city of Kansas City needed to make further improvements to the roadway, they enlisted the Walter P Moore team who had helped with previous upgrades. The new designs, this time on the east side of I-29, focused on increasing sight distances and driver safety and decreasing costly roadway additions in the future.

A portion of NW 72nd Street in Kansas City that has an improved sidewalk as well as a curb and gutter and added turning lane.

About the project

To continue to improve the NW 72nd corridor in Kansas City, Walter P Moore worked with the city to change the existing two-lane asphalt roadway into a three-lane roadway that included a continuous center turn lane, curb and gutter, concrete sidewalks, and modular large block retaining walls. 

Similar to the west side of I-29, the design of this east portion of NW 72nd Street focused on significant improvements to the roadway profile to increase sight distances and driver safety. Other infrastructure improvements were important, as well, including a water main replacement, adding storm sewer systems, and enhancing the stormwater quality treatment of the stormwater runoff to avoid adverse impacts to Lake Waukomis.

To address future traffic volumes at a busy intersection at N Overland Drive, Walter P Moore and the Kansas City staff also elected to design a roundabout. at the intersection of N Overland Drive. A new roundabout will avoid costly future traffic signal upgrades to this intersection, saving the city money and time.
