Officers issued 24 speed notices to motorists speeding down Pine Hill Rd-State Highway 1 into Cumberland St, in just over an hour.
Poor weather and road conditions did not deter motorists and the highest speed recorded was 70kmh in the 50kmh area, Dunedin Clutha Waitaki area prevention manager Inspector Mel Aitken said.
''Disgraceful results,'' she said.
The operation was the latest in a month-long campaign aimed at targeting dodgy driving behaviour in the city.
Another 10 motorists were issued with infringement notices for offences including failure to wear seatbelts and using a cellphone while driving.
Insp Aitken said the the intersection with Great King St was ''high-risk in terms of crashes''.
Police would continue to target poor driving behaviour, ''in an effort to reduce the harm to all road users'', she said.
