The work to make the suspected World World Two unexploded bomb safe, over ran for days and caused public transport delays in the Bromley By Bow area.
The Hammersmith & City Line was suspended between Whitechapel & Barking and the District Line between Whitechapel and Plaistow. The bomb was found in a river at Sugar House Lane, near Bromley-by-Bow London Underground station, at about 1151 BST on Monday 2nd June. The immediate area was evacuated following the discovery of the bomb.
A Police spokesperson said initially that cordons would be in place for three days and there are restrictions along the River Lee navigation from Bow Locks to Old Ford Locks.
