An Omaha construction firm, Ronco Construction Co., will build the new Lincoln train station.
Work on the $1.28 million station and new 800-foot canopy is expected to be finished by mid-June.
Lincoln's current depot building will remain but passengers will use the new station, 700 feet to the west.
The current tracks must be moved to accommodate the new Pinnacle Bank Arena.
Nine companies bid on the station construction job, said Randy Swanson, with PC Sports, a company monitoring arena construction.
The contract includes a new metal canopy over the platform, said Dan Marvin, arena project coordinator.
Amtrak will rent most of the 2,750-square-foot building, and will use the Lincoln station for crew changes. It added a 300-square-foot locker room to the original design.
The Joint Public Agency, the three-member group overseeing arena-related construction, also approved a $610,739 contract with Lincoln-based Stevens & Smith Construction for building the depot's platform.
That contract is higher than originally bid because the company hadn't considered the cost of insurance required when doing railroad-related work.
