Roads in Old Portsmouth have now been opened again after an unexploded World War Two shell was found.
The device was found at about 3.30pm in the building area where yachstman Sir Ben Ainslie’s America’s Cup bid headquarters is being constructed.
Police established a cordon at Portsmouth Cathedral to prevent people from accessing Sallyport and The Point.
A Royal Navy bomb disposal squad was called to the area and has now removed the shell.
Police were stopping traffic at High Street at its junction with Oyster Street in Old Portsmouth. The roads were reopened just before 5.30pm.
Frances Wyatt, 74, of Westfield Road, Southsea, said: ‘I went to get the bus and the police said there’s been an unexploded bomb found.
‘I’ve been coming down here for years and never had that happen before.’
Former Royal Navy sailor Russell Best, 55, of High Street, was allowed through to his home.
He said: ‘I was just coming down from work. My wife phoned me in the car and said there’s a World War Two bomb.
‘They’re generally handled very professionally by the navy or the army.
‘Hopefully it’ll all be cleared up in a couple of hours.’
The Anglican cathedral in Old Portsmouth has been opened to offer shelter to anyone who cannot go back to their home.
Police sergeant Longyear, second in command at the scene, said: ‘It’s just ordnance.
‘We’re going to advise people to (stay away).
‘It’s standard. It’s precautionary.’
