The Jefferson Street entrance to the Peoria County Courthouse will be closed starting Monday for drainage work and site improvements.
County officials say the project is expected to take two months to complete.
All public access into the courthouse will be through the Main Street entrance only during construction.
The sidewalk outside the Jefferson Street entrance will be closed from Hamilton Street to the ADA ramp. The parking lane will be designated for pedestrians. The first driving lane next to the parking lane will also be blocked off.
