how is Tinsley Viaduct and A631 road connected?
Tinsley Viaduct Tinsley Viaduct is a two-tier road bridge in Sheffield, England; the first of its kind in the United Kingdom. It carries the M1 and the A631 1,033 m over the Don Valley, from Tinsley to Wincobank, also crossing the Sheffield Canal, the Midland Main Line and the former South Yorkshire Railway line from Tinsley Junction to Rotherham Central. The Supertram route to Meadowhall runs below part of the viaduct on the trackbed of the South Yorkshire Railway line to Barnsley.
A601(M) motorway The A601(M) is a motorway in Lancashire, England. It is 1.3 mi long, and meets the M6 at Junction 35. It is a unique motorway within the United Kingdom as it has a dual carriageway section leading north from Junction 35 of the M6, with a single carriageway section (the only single carriageway section with motorway status in the United Kingdom) leading south, where it terminates at a T junction on a B road. The A601(M) is not the A601 under motorway restrictions, as is the usual explanation for such a classification in the UK. The A601 itself is the Derby inner ring road, over 100 mi away.
