The Mancunian Way is a two mile long motorway in Manchester, officially made up of the A57(M) and A635(M) motorways. The Mancunian Way was officially opened by Prime Minister Harold Wilson, on 5 May 1967. In the 1970s it was upgraded to motorway status as the A57(M) and the speed limit was raised to 50 miles per hour (80 km/h).At the time of its opening the Manchester Evening News referred to it as the "highway in the sky". The scheme cost was £5.5m (£89m in today's figures).
Just before the junction with the A34 is an unfinished slip road (stub) that ends 20 feet in the air, although it is hidden from the road by an advertising billboard. This was intended to be part of a dual carriageway into the city centre; this plan was suddenly abandoned as the planners hadn't realised the slip road would have been connected to Princess Street which has been a one-way street out of Manchester city centre in the opposite direction for over 60 years.
