PROVIDENCE, R.I. — The Roger Williams Park Zoo had to make an unscheduled closure after a construction mishap knocked out power to about half the zoo.

Zoo Director Jeremy Goodman tells WPRI-TV that construction in an upcoming exhibit on rainforests inadvertently hit a power line Monday morning.

He says that with power knocked out in several restrooms and no group events planned for the day, they decided the best course of action was to close.

Goodman calls it a minor issue, and says if it hadn’t been December, they likely would have stayed open despite the outage.

He expects power to be restored later in the day, and says the zoo is expected to re-open Tuesday.
