A “significant act of vandalism” caused extensive damage to Lights in the Parkway, forcing Allentown to close the annual holiday lights display Sunday.

Damage included bent light poles and posts, and crushed light bulbs throughout the display in the Lehigh Parkway. Port-a-potties were also pushed into the Little Lehigh Creek, according to a news release from the city.

“Somebody put a real effort into destroying something beautiful,” Mayor Matt Tuerk in a video he posted to Facebook, promising a criminal investigation.

The city in the morning said it had yet to determine if the damage would affect the rest of the Lights in the Parkway season, but in his video later in the day, Tuerk said a Move it Monday walk through would be held Monday in conjunction with the Jewish Community Center of the Lehigh Valley to celebrate Hanukkah.

He said, “90% of the lights are in great shape.”

Tuerk reiterated earlier statements from city officials that indicated it could be expensive to repair and replace the damaged displays during the current season, and posted a link to an Allentown Parknership page seeking donations to pay for the repairs.

“We’re hoping to get the car version back up and going as well,” Tuerk said.

The city said every effort will be made to keep the display going this season. The city’s public works department deployed crews to secure and evaluate the display.

“While we continue to evaluate repair options, please know that every effort will be made to keep the Lights in the Parkway tradition going with the resources currently available,” according to the news release.
