I-29 & Tiffany Springs Parkway Interchange header

Project Overview

The Interstate 29 Interchange with Tiffany Springs Parkway is part of a growing area of Kansas City, Missouri.  Because of the close proximity of Ambassador Drive to the interchange, and the development already in place along Ambassador Drive, many motorists exit I‐29 at Tiffany Springs Parkway and proceed northbound on Ambassador Drive.  This creates a right‐turn / left-turn situation that does not work well with the current geometric configuration of the intersections.  This project corrects that
inefficiency, and also upgrades the capacity of the infrastructure in
and around the interchange.

The interchange itself will be converted from a standard Diamond Interchange into what’s known as a Diverging Diamond Interchange.  In this configuration, traffic crosses from the right side of the road to the left side at two signalized intersections on either side of the interchange.  These crossovers allow for free flowing right‐turns in advance of the cross‐overs, and free flowing left‐turns between the cross‐overs. This enhances the safety and capacity of the interchange while keeping the costs of reconfiguration to a minimum.

Additionally, N.W. Prairie View Road will be expanded to four‐lanes south of Tiffany Springs Parkway, and will connect directly with N.W. Congress creating an alternative route to the Recreation Complex, Zona Rosa shopping areas, and the business district along Barry Road.  An additional lane will also be added to I‐29 both north and southbound, between Route 152 and Tiffany Springs Interchanges.

A public hearing was held February 28, 2012 at the Platte County Resource Center to gather public input regarding the design for the proposed project.  Approximately 15 people stopped by to learn more about the project.
