Three years ago, New Jersey, New York and Connecticut residents were left with piles of debris, battered neighborhoods and emotional scars drawn up by Superstorm Sandy.

As Sandy's ferocious storm surge pummeled the New Jersey coastline, homes and other pieces of infrastructure were dismantled. New Jersey Gov. Chris Christie would later call the damage "the worst we've ever seen."

Sandy made landfall near Brigantine, New Jersey, on Oct. 29, 2012, on an unprecedented path.

Nearly 150 people were killed as a result of the storm. At least 650,000 homes were destroyed throughout the eastern United States, according to the National Weather Service.

In the aftermath of the storm, nearly a quarter of New Jersey was without power.

Widespread evacuations were ordered for coastal areas as the storm churned in the Atlantic.

"Don't be stupid, get out and go to higher, safer ground," New Jersey Gov. Chris Christie said in advance of the storm.

Many residents didn't see Sandy's wrath until returning days, even weeks later once officials deemed it safe to reenter.

In what became an iconic image of the storm, the Jet Star roller coaster crashed into the Atlantic Ocean after the Casino Pier collapsed. The dismantled attraction was left sitting in the water for months, while adverse weather and ocean conditions prevented crews from safely removing the coaster.

The Jet Star has yet to be rebuilt as Casino Pier sits in a holding period, waiting for the proper permitting. Pier organizers are hoping to bring back the Jet Star and a ferris wheel, the last remaining attractions on the rebuild list.

"...we have invested millions of dollars into Seaside Heights and have single handedly brought tourism back to Seaside, but until we get the approval we may be at a standstill," Casino Pier Marketing Manager Maria Mastoris told AccuWeather.

The Borough of Seaside Heights is expected to discuss the agreement at a December meeting.

Instead of approaching New York and New Jersey from the south like a typical tropical system, Sandy invaded from the east.

A total of 24 states were impacted by the storm, resulting in more than $50 million in damage.

Sandy devastated areas across New York, including parts of Manhattan in New York City.

A record high water level of 13.88 feet was recorded at Battery Park, New York, at the height of the storm.

Public transportation was shut down for days after the storm. Subway systems, trains and major airports were closed as flooding wreaked havoc throughout the region.

Three years later, work is still being done to repair and restore completely some transit systems. New Jersey Transit received an additional $71 million to support "important repair and resiliency projects," a press released stated.
