In February 2012 Labour-controlled Manchester unanimously passed a 20mph motion (proposed by a Lib Dem). In March 2012 the Council Executive agreed to investigate funding for 20mph on all C and Unclassified roads. Estimated cost £2.8m (Total 20) or £41m (with calming). In May 2013 the Executive agreed £500,000 from public health funds to improve road safety. Three areas were prioritised for Phase 1 covering 16% of the network.
Area 1 – Gorton (Collision Hotspot, Social Deprivation, High Population Density)
Area 2 – Miles Platting, Newton Heath, Ancoats and Clayton (Social Deprivation, high degree of community engagement)
Area 3 – Hulme, Moss Side and Fallowfield (Maximise benefits of the complementary Bus Priority Scheme on the Oxford Road Corridor)
In February 2014 Traffic Regulation Orders published. Strap line 20 is Enough logo with smiley face featured on banners from school railings. Roadpeace, Key 103 Radio and student volunteers engaged - with access to £200 grants.
In March 2014 councillors, police, schoolchildren and campaigners gathered at Clayton Park for official launch.
In Spring 2016 the Velocity Project funded by Cycle City Ambition Grant created series of Cycle Super Highways, some on main arterials - where speed limit remains 30mph. Most of adjacent network became 20mph. £500,000 pays for implementation - again from Public Health monies.
Much of the 20mph rollout has been allied to other transport projects improving public transport or cycling facilities funded by public health budgets. It is uncertain how much of the network is 20 mph (16- 46%). Funding is uncertain and the council "plan traffic surveys before and after the introduction of the limits to monitor results before considering whether to extend it". "Enforcement is targeted at locations where there has been serious or fatal road accidents" said police.
The 20mph Champion is currently Cllr Ollie Manco. Key supporters include the Executive Member for the Environment, Cllr Kate Chappell and Transport for Greater Manchester Cycling Champion Cllr Chris Paul.
Traffic congestion is threatening economic growth. Lower speeds are seen as key element in encouraging modal shift away from car use towards public transport, cycling and walking.
In May 2017 electors from ten local authorities will vote for the first Greater Manchester Mayor with police and transport responsibilities.
