This is the moment the London terrorist plowed through pedestrians on the Westminster Bridge — and sent a woman plummeting in the Thames River in his deadly wake.

The footage, captured on a CCTV camera south of the bridge, shows the Hyundai i40 barreling along the span at 70 mph, and the woman plunging into the river.

“She is alive but undergoing urgent medical treatment,” said a spokesman for the Port of London Authority, the Sun reported.

The attacker, who officials said was inspired by “international and Islamist-related terrorism,” crashed his car into a railing outside of the Palace of Westminster, knifed unarmed officer Keith Palmer to death, and was finally shot dead by police.
