Downtown Construction

The Downtown Construction Project at IL Route 171 (State Street) and IL Route 7 (9th Street), overseen by the Illinois Department of Transportation (IDOT), is intended to alleviate traffic congestion through downtown and heading toward and over the IL Route 7 (9th Street) high level-bridge and through downtown along State Street. IDOT reports that segments of IL Route 7 and both sides of IL Route 171 have pressing safety improvement needs. As part of this project, the City is replacing water mains and water service laterals and installing new streetscaping.

If you have questions about the project, please contact: 
Dan Hansen, City Engineer at (815) 838-0549, option 8 or email Dan Hansen

Project Improvements

Project Updates

This week they will finish back filling, frame the staircase, and begin curb and sidewalk framing/grading. The landscaper has begun installation of outcropping at the corners of state and 10th and continued working on the limestone piers on state street.

April 1, 2019 - D Construction is continuing to frame the barrier wall on the north side of 9th and will have it poured by the end of the week. Water service installations and retirement of the old Commerce Street watermain between 9th and 10th will also be completed by the end of the week. Electricians have completed re-installation of the refurbished lighting units on the east side of State Street. The mason has begun installation of the masonry on the piers along State Street and will continue through the beginning of this week. Hoppy’s Landscaping will also continue installation of the outcropping along State Street. D Construction will follow with concrete base course installation and the Hoppy’s with paver installation.

March 28, 2019, April 2-3, 2019 - A temporary one-day closure of 10th Street at the railroad crossing. Access to the South Public Landing/Commerce Street Parking Lot will be maintained via the north entrance from 9th Street. The closure will be in effect until 3 PM today.

March 25, 2019 - D Construction has completed installation of the barrier wall footings on the North Side of 9th Street.

Excavation to tie in the watermain installed on 9th street last year to the existing water main on Commerce between 8th and 9th is ongoing and will be followed up by watermain installation, testing, and service installations. Excavation and framing for the proposed barrier wall footing will continue through the week as well.

March 11, 2019 - D Construction has began removal of existing sidewalk along the North side of 9th Street from Commerce St to State St. Upon completion of the North side of 9th, Removal and replacement will begin on the South side of 9th.
