KDOT

Project Number:	1287
Organization:	KDOT
Project Name:	I-435/State Ave Diverging Diamond Interchange (DDI)
City(ies), County(ies), State:	KCK, Wyandotte, KS
Routes, interchanges and/or intersections:	I-435/State Ave Interchange
Primary Project Mode:	Highway/roadway
Supplementary Project Mode(s):	* Active Transportation * Bridge * Freight * Transit ) The conversion of an existing partial cloverleaf interchange to a diverging diamond interchange(DDI) will improve the overall efficiency and safety of the interchange for both motorists and freight traffic. I-435 feeds into the national truck corridors of I-70 and I-35 and connects local populations, activity centers and Industry to outside markets. Motorists will find a facility with much improved traffic flow with a configuration designed to reduce congestion and improve mobility while improving access and connectivity to the many activity centers in the project area.
Project Purpose:	* System expansion (added capacity) * System preservation, rehabilitation or replacement * System operations and management )
Project Description:	Reconstruction of the interchange to a diverging diamond interchange (DDI) to replace an existing partial cloverleaf configuration. Motorists and freight would be the primary users of the improvement and transit riders on Route 101 that travels through the interchange. Bicyclists and pedestrians will also be primary users along State Ave.
Scope:	Motorists, freight shippers, transit riders and bikes/peds will be served by this project which is to construct a DDI at I-435 and State Avenue. The project length, being that it is an interchange is .001 ft. This improvement would serve the transportation needs of a growing and thriving activity center. KDOT anticipates these improvements being needed in order to address the transportation system’s needs that have arisen from the continued development within the Village West area. These are critical corridors where there is strong diversity of the current and proposed land uses and developments. Safety is also a concern that will be addressed with the construction of the DDI since no left turns must clear opposing traffic and all movements have discrete lanes and most movements are controlled by traffic signals.
