Multiple New Jersey attractions have reopened just in time for the Labor Day weekend.

The Bergen County Zoo has reopened to the public with newly installed upgrades to help enforce social distancing and offer easy access to hand sanitizing stations.

Face masks must be work at all times while at the zoo.

Tickets must be purchased online prior to the entry for morning or afternoon sessions. The zoo will be closed in between sessions for cleaning.

The zoo has been closed since March.

Liberty Science Center in Jersey City also reopened Friday to members and on Saturday to the general public.

"It's exciting after six months of being closed and all the safety measures we've put in to protect our members and staff," says President and CEO of Liberty Science Center Paul Hoffman. "And then the activities we've introduced that are really immersive and are low touch or no touch."

Anyone coming to the center must have their temperature taken and wear face coverings. A 25% capacity will be enforced.

The Liberty Science Center will be open Sunday and Monday from 10 a.m. to 5 p.m.
