CURRENT or COMING SOON PROJECTS:
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.
