The Cartoon Network is the group behind a planned street carnival in downtown Lawrence.

Commissioners gave approval for promoters to close Eighth Street from Massachusetts to New Hampshire street on April 19 for a carnival and music concert. The street will be closed from 9 a.m. to midnight.

Commissioners were told the free event basically is part of a promotions campaign for Cartoon Network’s Adult Swim programming, which features cartoons for an adult audience during the overnight hours.

The Whips, a band from Athens, Ga., is scheduled to be the headline music act for the event.

On a 4-0 vote, commissioners approved plans for the event, contingent upon all the carnival games and advertising being appropriate for all ages. Mayor Rob Chestnut was absent from the meeting.
