The bus station, which is used by 2.5 million passengers a year, was closed while the work was carried out. 

It was scheduled to take up to eight weeks but has been completed early and bus passengers are once again able to use the bus station.

Chris Kershaw, Transport for London's Head of Infrastructure, said: 'This project is an excellent example of collaboration between TfL, London Borough of Barnet and National Express.

'The fact that it has been completed before time is a testament to the dedication and commitment of all those working on the project. 

'This is a very busy station with thousands of passengers passing through it each day so we are pleased to be able to return services to normal quicker than expected.'

The resurfacing work involved replacing the block paving on the road with tarmac. 

Passengers were required to alight a stop early because of the works.
