The controlled detonation of a suspected Second World War bomb discovered in Exeter is expected to take place by Saturday evening.
The examination and detonation of the device was passed to the Army in the morning.
Royal Navy Explosive Ordnance Disposal (EOD) specialists are also on the scene and they continue to assess the device, which measures 2.5m by 70cm.
Lieutenant Baxter-Watt, Officer in Charge Southern Diving Unit 1, said the unit was "called to a suspected item of ordnance at the University of Exeter on Friday morning".
"After [an] initial assessment, the item was classified as a German WW2 air-dropped bomb, a 100m cordon was established and the bomb stabilised.
"The Royal Navy has since handed the scene over to the British Army due to the specialist machinery required for excavation and protective works prior to the bomb being rendered safe."
About 2,600 properties have been evacuated in the vicinity of Glenthorne Road, where the device was found on Friday.
After the detonation takes place, assessments will be conducted to make sure the area is safe before residents can return home.
Local police forces were called to Glenthorne Road following reports that a possible unexploded Second World War ordnance device had been located.
After an initial 100m cordon was erected and the evacuation commenced, the Royal Navy bomb disposal team worked through the night to establish a walled mitigation structure.
A 400m cordon is currently in place.
Devon County Council has also implemented road closures and diversions, advising motorists to avoid the affected area.
