Construction Updates






Please be patient and cautious.  Many improvements in various locations throughout O’Fallon are underway or about to begin.  We apologize for any inconveniences but SAFETY of both the general and public workers is our main concern.  Closures are unfortunately inconvenient, but necessary to bring these projects to timely completion.

North Green Mount Road (Regency Drive to Highway 50)  - On Tuesday, May 30, 2017, the traffic lanes on Green Mount Road, from Pierce Boulevard to Hwy 50, will be switched over due to construction. After the switch-over, northbound traffic will use the northbound lane and southbound traffic will use the center/turn lane. The project is scheduled to be completed on November 1, 2017, weather permitting.

Milburn School Road Construction - Milburn School Road, between Savannah Hills and the roundabout at Milburn Estates/Merriam Parkway, will be closed to traffic beginning Tuesday, May 30, 2017. It is anticipated that work will be completed and the road will re-open to traffic on September 30, 2017, weather permitting. 

A detour route will be on Simmons Road, Venita Drive, Frontage Road, and Old Collinsville Road. Access to the OTHS Milburn Campus from Merriam Parkway will not be affected by the construction.

The work will consist of storm sewer and curb installation and pavement construction and will be completed by Stutz Excavating.  

Residents who live in the affected areas will have access to their properties throughout the project, though occasional delays may be encountered.

Cambridge Boulevard at North Green Mount Road - Cambridge Boulevard, between North Green Mount Road and Indian Creek Drive, will be closed to through traffic beginning Thursday, March 2, 2017.  Access will be maintained to all businesses with entrances on Cambridge during the closure. It is anticipated that Cambridge Boulevard will be re-opened to through traffic in approximately 2 months, weather permitting.

The work will consist of installing new storm sewer, curb and gutter, concrete pavement and ADA compliant sidewalks as part of the North Green Mount Road Improvements project.
