What will the project include?

5thStreet

  • replacement of the Fairgrounds Road overpass
  • new sidewalks along Fifth Street, Veterans Memorial Parkway and Fairgrounds Road
  • new bike lanes at the Fairgrounds Road overpass                                                                           

Why is the project needed?

The project will help improve traffic flow, as well as access to and from Interstate 70 at the very busy Fifth Street interchange.  This will improve the overall safety of the area and provide better access to a variety of St. Charles County‚Äôs top attractions, including the Ameristar Casino, Historic Main Street and the St. Charles Convention Center.

***Please Note: this project is not a part of the City of St. Charles' Fifth Street Gateway Project currently under construction between Bass Pro Drive/Ameristar Boulevard and First Capitol Drive.

What kind of traffic impacts will there be?

The project will require nighttime and weekend lane restrictions, as well as the narrowing of Interstate 70 in both directions.  Other impacts will include:

  • an around-the-clock lane closure on westbound I-70 between Fifth Street and Route 94 from late March to late May
  • an around-the-clock lane closure on westbound I-70 before Fifth Street in early spring
  • an around-the clock lane closure on eastbound I-70 in early spring
  • a 120-day closure of the Fairgrounds Road bridge in late spring 2016
  • a weekend closure of 5th Street in fall 2016
  • the closure of the commuter lot at Fairgrounds and I-70 throughout the project.  The nearest commuter lot is at I-70 and Zumbehl Road.

Crews will limit impacts on holidays and large scale events,         such as the Festival of Little Hills.
