Milestone Contractors will make a traffic switch at the new railroad overpass in Columbus on Sunday, weather permitting. Under the new configuration, crews will finish work to tie-in the new alignment to existing State Road 46. The estimated $35 million project is being jointly funded by the Indiana Department of Transportation, city of Columbus, Bartholomew County, Cummins Inc. and the Louisville Indiana and CSX railroads. The contract completion date is June 2021. The overpass project was developed in response to a projected increase in railroad traffic on the Louisville Indiana Railroad tracks. INDOT has agreed to pick up half of the total cost, while the city, along with other partners, pick up the half of the tab. The railroad has leased its tracks running through Columbus to CSX, which is expected to result in an increase in train traffic, train speed and delays at intersections involving rail crossings through the city, with the State Road 46/State Road 11 intersection expected to have the most delayed local traffic.
