Some streets in Downtown Youngstown remained closed early Monday following a weekend event at the Oh Wow science center.

Part of Central Square and W. Federal Street is closed between Wick Avenue and Phelps Street. Due to construction.

All of W. Commerce Street and the intersection at Phelps Street and W. Boardman Street are closed and do not permit thru traffic.

The roads were closed to allow Oh Wow's Silly Science Sunday event that included several public experiments.

There's no word on when the streets will open again.
