This is the heart-stopping moment a driver plunged 40ft off an unfinished bridge while trying to follow Google Maps.

Rudie Heru Komandono, 61, had set up his smartphone on the dashboard of his black BMW 3 Series and opened the tech firm's app before entering the address of a friend.

But while Google had mapped the new road in East Java, Indonesia, and even rerouted him away from the incomplete highway, the driver was confused by the changing directions being displayed.

Instead of taking a slip road, Rudie passed through a gap in a concrete barrier and ploughed ahead. Moments later, the luxury sedan hurtled off the incomplete flyover and crashed on a road below.

CCTV footage shows his BMW launching from the bridge on April 9. The car landed bumper-first on the pavement, narrowly missing passing vehicles.

Medics later arrived at the scene to treat Rudie and his female passenger, Endang Sri Wahyuni, 47, who both survived the nightmare crash with minor injuries.

Rudie said: 'The road suddenly became dark and there were no other cars. Then I realised there was a problem when the car started falling and crashed on the ground.

'My friend said she is not getting in the car with me again. But it was not my fault. I was trying to follow the GPS on my phone, but it was confusing.

'I'm worried about the insurance for the car. I don't think it can be repaired.'

Inspector Aswoko, Head of the Law Enforcement Unit of the Gresik Police Traffic Unit, said Rudie had slipped into the restricted area through a gap in the traffic barriers.

There are lanes on either side to exit the elevated expressway - which Rudie should have taken - but he carried on driving straight, which took him to the unfinished bridge on the JI Tol Manyar - Mojokerto road.

Inspector Aswoko said: 'The driver of the car was too focused on looking at Google Maps. He didn't realise he had passed the barrier that was blocking access to the unfinished toll road.

'The driver and passenger have been treated by a doctor at the hospital and did not suffer serious injuries. They have been allowed to go home.'

Officers said they have since closed the gap that the car had passed through. They will also put up warning signs to prevent other drivers from making the same mistake.

Inspector Aswoko added: 'Traffic officers have taken measures to prevent an incidentfrom happening again. The construction company will also be interviewed to discover why the bridge was not fully sealed off.'
