Extreme heat may have caused a bus to sink into an underground parking garage in Lake Success on Tuesday night, leaving its front end suspended in the air some 24 hours later, according to North Hempstead town officials.

“There is a chance it was heat-related because the garage deck is asphalt, which is known to buckle from heat stress,” Umberto Mignardi, a spokesman for the Town of North Hempstead, wrote in an email to Newsday. Town officials are waiting on an engineer's report to determine the definite cause, he added.

No one was injured when the rear end of the coach bus, operated by M&V Limousines of Commack with only the driver on board, sank through the top of a parking garage at 1979 Marcus Ave. just before 5:30 p.m. on Tuesday.

A handful of town inspectors examined the surrounding buildings and garages on Wednesday, according to Mignardi. “We will be immediately closing anything deemed suspect,” he wrote.

Town officials are waiting on the property’s landlord to hire a structural engineer to evaluate the scene, Mignardi said. That engineer will have to figure out how to extract the bus, which is still bulging out of the ground with its front tires suspended in the air — a task Mignardi said will require a crane.

Concrete cracking under extreme heat is not uncommon. State Route 110 cracked near Duryea Road in Melville Tuesday and emergency repairs had to be made. Tuesday, temperatures in Islip hit 101 in the second and hottest of the three-day record-breaking heat wave in the region this week.

In a 2013 heat wave on Long Island, state officials reported five instances of roadways buckling within the first three weeks of July. Those included stretches of roadway along the Long Island Expressway at Exit 67 in Yaphank, a portion of Route 25 at the intersection with Route 347 in Lake Grove and part of the Long Island Expressway near Exit 68 in Manorville.

While the main parking structure in Tuesday’s collapse does not have a history of any violations, according to Mignardi, an entrance ramp to the building was ticketed in 2022 for a violation that has since been fixed. That entrance ramp has remained closed until the repair is certified, Mignardi said.
