PETERSBURG, Ky. (AP) — Northern Kentucky's Creation Museum is evolving into a larger facility.

The museum will add 663 parking spaces, outdoor canopies and a maintenance building and will move its main entrance as part of a $500,000 upgrade, according to a report in The Kentucky Enquirer.

The controversial museum, which uses literal interpretations of the Bible to tell the earth's history, welcomed its 250,000th visitor five months after its opening on Memorial Day. The museum had expected to get 250,000 visitors its entire first year.

The larger-than-expected crowds left the facility with an overflowing parking lot, forcing staff to park miles away.

The Boone County Planning Commission approved the plans by an 11-1 vote, the newspaper reported.
