Six steel beams were dropped by the crane. No one was injured in the incident.

CLEVELAND — It was a boom heard throughout downtown Cleveland on Thursday.

Police say a crane dropped six steel beams on top of the garage at the construction site of the Lumen apartment building, located at E. 14th Street and Euclid Avenue in the Playhouse Square district. The incident happened around 1:00 P.M.

Euclid Avenue from E. 14th to E. 18th streets was closed for several hours. Officials from Playhouse Square informed 3News that the road was re-opened at 5:15 P.M.

EMS crews have told 3News that no injuries have been reported. Witnesses on scene say the moment sounded like a loud "boom."

"I was having lunch and we heard a boom," witness Pete Marea told 3News "We all ran to the window and we saw a thing of smoke and cloud and those yellow supports were flying all over the place. Then we saw the two beams sticking out of the ground and the crane dangling up there."

3News investigative reporter Rachel Polansky spoke with a representative of the Gilbane Building Company, who are working on The Lumen. According to the company's director of communications, Wes Cotter, six structural beams lifted by a crane shifted and fell. No workers were injured.

Gilbane is investigating the incident to figure out what happened and to ensure that it doesn't happen again. Cotter emphasized that safety is the company's top priority.

Cindi Szymanski, Assistant Director, Brand Marketing & Communications at Playhouse Square told Polansky, “There has been no impact on the Playhouse Square theaters or surrounding businesses or parking facilities. Tonight’s shows will go on as planned.”
