Project Information 

ONLINE PUBLIC MEETING: The Missouri Department of Transportation invites you to take part in an online public information meeting, beginning Monday, Oct. 26, and continuing until Monday, Nov. 9, regarding the replacement of two bridges along the Interstate 29 corridor in Platte County, MO. Please scroll down to the comment form below after reviewing the project information and plans.

In this project, MoDOT will be replacing the I-29 Bridge over 56th St. and the Waukomis Drive Bridge in Platte County. 

How will this project benefit me? 

This project will provide two new and safer bridges. It will also add sidewalk/share use path and lighting underneath the bridges. A left turn lane will be added to 56th Street and Waukomis Drive/Rte AA for additional traffic safety. 

What is the time line for this project?

Both bridge projects are anticipated to begin in spring of 2021 and expected to be completed by the spring of 2023.

How will this project impact traffic? 

In order to minimize impacts on I-29 traffic, some ramps and roads will be closed during different phases. Detours will be in place during construction.

 

What will this project cost? How will the project be funded? 

The construction cost for these two projects is approximately $7 Million dollars and is funded with MoDOT funding.
