The Lewis and Clark Viaduct is a series of bridges that span land and water in Kansas City, Kansas. The Viaduct provides a vital link for I-70 across the Kansas River and connects Kansas City, Kansas and Kansas City, Missouri.
The Kansas Department of Transportation (KDOT) conducted a study to examine the condition of each of the nine bridges making up the Viaduct and developing a priority phasing plan for rehabilitation and/or replacement of the existing bridges. The Lewis and Clark I-70 Viaduct Study was completed in December 2012 and the final study is located here: The Lewis and Clark Viaduct Concept Study.
The purpose of the Lewis and Clark Viaduct Concept Study was to develop a preferred concept for rehabilitation and/or replacement of the nine Lewis and Clark Viaduct bridges and associated roadway improvements within the study area that facilitates safe and efficient traveler mobility and can be implemented in phases. The study responds to these needs in a manner that:
• Improve infrastructure condition by rehabilitating or replacing aging and deficient bridge and roadway infrastructure, thereby decreasing maintenance costs.
• Enhance traveler safety by improving geometric design conditions (including roadway and bridge shoulder widths, horizontal and vertical curves, and lane continuity issues) to address high crash locations and pedestrian conflict points within the study area.
• Improve traveler mobility and accessibility by incorporating improved study area routing, signage and wayfinding while maintaining multimodal access for transit, bicycles and pedestrians as a part of the roadway and bridge improvements.
• Support sustainable design by integrating environmental, multimodal and visual
design applications into the proposed roadway and bridge improvements, where
practical, to enhance the quality of life and aesthetics of the study area.
• Support economic development and redevelopment initiatives within the Kansas City, Kansas Downtown Master Plan to create a vibrant downtown that is economically, physically and culturally diverse.
