Union Pacific will strengthen Wyoming's transportation infrastructure by investing $15 million in the rail line between Rawlins and near Rock Springs.
The project, funded entirely by railroad began June 15 and is scheduled to be completed by the end of September.
The railroad will replace 127,200 crossties and install more than 61,200 tons of ballast. In addition, crews will renew the surfaces at 18 crossings. The project is one of nearly 1,500 UP will complete across its 32,000-mile network this year to help improve train operating efficiency, reduce motorist wait times at crossings and enhance safety.
