KEARNEY, Neb. (AP) — An official says attendance has been climbing at The Archway museum that spans Interstate 80 in south-central Nebraska’s Kearney.

Marketing coordinator Jace Robinson said that, since March, there’s been higher attendance every month other than July. He says August is looking good, too. Robinson didn’t release specific numbers.

The monument spans Interstate 80 and has exhibits that commemorate the Oregon, Mormon and California pioneer trails. It has struggled with disappointing attendance since its opening. Nearly 250,000 people visited in 2001, but last year’s attendance was just under 50,000.

Robinson says many factors could have contributed to the rising attendance, including the opening of the Cherry Avenue exit off the interstate, which has eased access for visitors.
