A 20mph speed limit could be coming to Manchester. Here's what happened when it was introduced in Cardiff

manchestereveningnews.co.uk:

Drivers across Manchester could soon face a 20mph speed limit on residential roads across the city. Under new plans revealed today, main roads would also be brought down to 30mph.

The proposals effectively confirm that Mancunian Way will permanently become a 30mph road, having been temporarily lowered in late 2022 after a safety review.

Speed limits will be cut on eight 40mph roads, including the A34 Kingsway and A663 Broadway. The Manchester Evening News understands city centre streets would be included alongside suburban residential roads in the 20mph proposals.

Speaking at a town hall meeting today (Tuesday), Kevin Gillham, Manchester council’s head of citywide highways, said he was ‘aware of some of the backlash’ when a wholesale urban 20mph limit was implemented in Wales, which led to the decision to keep main roads at 30mph.
