The whole of Gloucester Street has been closed because of what police have called an 'unsafe building structure'.

The government says parts of the waterproofing on the roof of the Granite Block hospital are being checked urgently because strong winds have caused parts of the flashing to loosen.

"Motorists and pedestrians are advised that Gloucester Street and Newgate Street is currently closed.

"This is due to parts of the waterproofing on the roof of the Granite Block hospital needing to be checked urgently because strong winds overnight have caused parts of the flashing on the granite block of the hospital to loosen.

"Engineers are currently working on site to assess the situation.

"The rest of the hospital is unaffected and is functioning as normal, however, patients and visitors can only access the hospital from the Parade entrance.

"Patriotic street car park remains open but visitors/patients will have to access the hospital via Kensington Place through to the Parade.

"HCS apologises for any inconvenience caused."

Jersey Fire and Rescue are on the scene to assess the situation.

We're asked to avoid the area 'until further notice'. 

Anyone who can't get to a hospital appointment today will have it re-booked - and anyone who needs to get to the Breast clinic on Newgate Street is asked to go to the Outpatient Department instead.
