IDOT – IDOT says nighttime lane closures will start tonight at 7 on Illinois 146 through Anna in Union County so patching and paving operations from the Jonesboro Square to the Illinois 146/Old US 51 intersection in Anna can take place. Officials say periodic closures of minor side roads and parking lanes will be necessary to complete this work. It is anticipated the project will last two months. Delays are expected. Flaggers and traffic control devices will be in place to direct you through the work zone.
