An ancient road between
Glossop and
Ashopton was the
Doctor's Gate, which follows the Shelf Brook between Shelf Moor and Coldharbour Moor. It is marked on some maps as a
Roman road, though this is disputed. The route is now popular with walkers and
mountain bikers. In 1932, an
Iron Age axe thought to be more than 2,000 years old was found near the site of this road. The current road further south was designed as a
toll road to improve communications east of Glossop, which was expanding as an industrial town. It was originally called the Sheffield to Glossop Turnpike and run by a
turnpike trust, the Sheffield and Glossop Turnpike Trust, and it shortened the route by 15 miles. An
act of Parliament to build the road, the '''''' (
58 Geo. 3. c. xxxv) was passed, and construction was financed by the
Duke of Norfolk (Lord of the Manor of Sheffield and Glossop) and the Duke of Devonshire (owner of the Ashop Valley). William Fairbank, a surveyor from Sheffield, designed the road, with construction being undertaken by
John Macadam. The road opened on 23 August 1821, having cost £18,625 to build The road was immediately popular and increased toll collections of traffic heading to Glossop. However, improvements in the rival Sheffield and Chapel-en-le-Frith Turnpike, with
Winnats Pass being bypassed in 1819 by a new route via
Mam Tor, removed much of the advantage of the Snake Pass route, which also suffered from a greater susceptibility to snow, leading to less than anticipated income. Subsequent acts of Parliament extended the turnpike trust; the '
(6 Geo. 4. c. xcviii) and the ' (
14 & 15 Vict. c. cxxxiii). Tolls were abolished on the road in June 1870, in return for the local highway boards taking over maintenance responsibilities. The
Local Government Act 1888 transferred responsibility for maintenance to the new
county councils: in the case of the Snake Pass section of the turnpike road, this was
Derbyshire County Council. The eastern end of the pass is by the
River Derwent. The river is bridged by the Ashopton Viaduct, built as part of the
Ladybower Reservoir project between 1935 and 1945. In 1946 the road was designated part of the
A57 road. Traffic levels on both passes remained similar until the 1980s, Despite Sheffield and Manchester being among the
largest UK cities by population, there is no direct motorway link between the two. The
M67 was originally proposed to be a Manchester to Sheffield motorway, but only a small section bypassing
Denton and
Hyde was actually built. The
Woodhead Tunnel, which carried a
Sheffield to Manchester railway line, was closed in 1981, and it was proposed to use it as part of a motorway link but linking the cities by road would have meant constructing many costly tunnels and viaducts across the Peak District. Consequently, the plans were shelved, but reports in December 2014 announced a revival of the ambition for a road tunnel to avoid the passes. In 1979, the
Department of Transport considered closing the road with traffic to be diverted to use the
A628. The road remains popular with drivers. A 2008 survey by
Caterham Cars rated Snake Pass the best driving road in the UK. The following year, it was listed as one of the best roads for driving in Britain by
Auto Trader magazine, who described it as "offering unparalleled views over Manchester". ==Safety==
