A delay in a Springfield highway project could push back the opening of Springfield’s upcoming MGM casino by a year, leading to an estimated $125 million in foregone state revenue and tens of millions of dollars in additional costs for MGM.

MGM Springfield President Michael Mathis yesterday asked the state Gaming Commission to incorporate the Springfield highway construction into the casino project’s timetable.

“We just want to make sure that we open as well as you can,” Mathis said in a statement. “It goes back to the adage, you only have one chance to make a first impression.”

The new schedule, which was endorsed by the city of Springfield, would push back the planned opening from late 2017 to September 2018, or soon after the highway project’s completion. Springfield would be compensated by MGM for the delay, including $1 million for public safety.
