New York's 9/11 museum take shape beneath Ground Zero

The museum is set to honour the memory of the almost 3,000 people who died on 9/11

Following a year long construction shutdown, brought about by funding disputes and extended by the impact of Hurricane Sandy, work has once again got underway at New York's 9/11 museum ahead of its expected opening in spring of 2014.

The museum is set to honour the memory of the almost 3,000 people who died on 9/11 and will include exhibitions such as a "Survivors Staircase", which hundreds of people used to escape from the World Trade Center during the attacks in 2001.

The museum will use the twisted wreckage and rubble of the collapsed building to tell the story of the attack, the victims and the remarkable tales of survival.

It will also explore the historical impact of the events of September 11 and scrutinise the continuing role the event plays. From a mezzanine, patrons will be able to peer into a deep, nave-like hallway nicknamed the South Canyon.

The hall's high western wall will eventually be covered with artwork that people around the world made in tribute to the victims after the attacks. Another exhibit will feature supportive notes and letters.

About 130 workers are at the site each day and there is much left to be done, but officials with the museum said the project is on track to open to the public in the spring of 2014.

Some of the museum's most emotion-inspiring artifacts already are anchored in place.

As well as the "Survivors' Staircase" the museum will contain stell that was etched with religious symbols by rescue workers and parts of a retaining wall that held back the Hudson river.
