A worker on the scene where a bus knocked over a traffic pole on Manners Street.

A GoWellington bus which took a corner too wide ended up taking out a traffic light this afternoon.

The trolley bus, with passengers onboard, was in the left lane rounding the corner out of Manners St on to Victoria St when it caught a traffic pole, toppling it about 1pm.

John Coppin, who was working at Barkers Studio, was looking out the window at the time.

"I just saw it catch the pole and then it just went boof," he said.

"It didn't mount the kerb ... It looked like it caught on one of the stringy bits, but I don't know."

The driver got off the bus to survey the damage, as well as an elderly lady who seemed to have got "a bit of a fright".

Contractors were on the scene repairing the damage.
