Route 109 MoDOT Project

May 21, 2019

The contractor is scheduled to shift traffic to the west side of Route 109 on Wednesday, May 29, weather permitting.  There will be one lane in each direction on Route 109 and a temporary signal in place for access to the Route 100 entrance/exit ramps.  Cambury Lane, Hawthorne Village Parkway, and Main Street will remain open with access to Route 109 during this traffic configuration.  This traffic shift will allow the contractor to construct the east side of the new bridge and roadway and is expected to be in place until mid August.  

April 29, 2019

MoDOT's contractor, Gershenson Construction, is scheduled to begin this project on May 6, 2019.  On June 3, weather permitting, traffic is scheduled to be shifted to the west side of Route 109 to allow for construction of the east side of the new bridge and road.  Traffic is scheduled to be shifted onto the newly constructed east side of the bridge and roadway in early fall.  These are the anticipated times based on the contractor's initial schedule and may change.  Any changes to the schedule will be updated by MoDOT and placed on the City website.  Please use caution when traveling through this improvement project.

Project Overview

This is a joint project with MoDOT to improve Route 109 from just north of Route 100 to Main Street. The project will replace the existing Route 109 bridge over Route 100, construct new roundabouts at Main Street and the eastbound ramps, construct a new pedestrian tunnel under Route 109, and widen Route 109 to extend the current four lane configuration from north of Route 100 to Main Street. Construction of this project is proposed to begin in 2019 and Route 109 will remain open for the entirety of the project.  Here is a link to the MoDOT website for this project.
