In mid-March 18, 2013, a KDOT replacement project began on the Riverview Avenue Bridge spanning over I-70 (MM 224.9) in Wyandotte County. This is the first part of KDOT's ten-phase K-7 and I-70 Interchange Project. Riverview Avenue project work includes replacement of the existing bridge along with the realignment of a section of Riverview Avenue and 122nd Street to accommodate the new longer bridge. For information on this project, including additional impacts to traffic on I-70/Turnpike, please visit the project web site.
Reconstruction of the Wittenberg Road Bridge and re-decking of the 29th Street bridge crossing over the Turnpike/I-470 near mile markers 180 and 181 in southeast Topeka are set to begin soon, weather permitting.
The Wittenberg Road (Br. No. 181.190) and the 29th Street (Br. No. 180.510) Bridges have deteriorated to the point they need to be reconstructed. LG Barcus is the contractor for the project. Construction on both bridges are expected to be complete in November. Kansas Turnpike/I470 travelers can expect intermittent lane closures throughout the project.
Most bridges crossing over the Turnpike are approximately the same age – 50+ years. During the next several years, KTA will be re-decking many of these bridges. Future bridge re-decking schedule will be determined by annual bridge inspections.Map showing Wittenberg & 29th Street bridges
