Three building workers injured when 14 storeys of scaffolding collapsed are comfortable in hospital, police say.
The men were dragged from wreckage at the Milton Keynes building site after the collapse on Tuesday.
Traffic was returning to normal by lunchtime on Wednesday after police lifted the cordon round the site once it had been declared safe.
People who work in the area were allowed to return to their offices and motorists could recover their vehicles.
Parking amnesty
Traffic wardens had declared an "amnesty" on abandoned cars in the area, saying those who had to leave vehicles parked within the cordon would not be fined.
An investigation has begun to find out why the scaffolding collapsed at the site of a new Jurys Inn hotel.
Eyewitness Nick Reynolds said: "It came down like a pack of cards", while others said the collapse sounded like a roll of thunder.
The managing director of site contractors McAleer and Rushe, Eamonn Laverty, blamed high winds.
Up to 200 people were working at the Witan Gate site but many were on a lunch break when the scaffolding collapsed.
