The A671 is a road in the North West of England, that runs between Oldham, Greater Manchester and Worston, near Clitheroe, Lancashire.

[1] The southern end of the road, formerly part of the A627,[2] was the main route from Oldham to Rochdale until it was bypassed by the A627(M) motorway in 1972.

The 3-mile (4.8 km) section through the town is called Market Street, and has several speed cameras as well as being the scene of a number of accidents.

There have been a large number of road traffic incidents on the A671 as it passes through the small hamlets of Broadclough and Weir near Bacup including fatalities.

Currently police are monitoring the road[6] and there have been calls from local residents, led by County Councillor Jimmy Easton,[7] for the creation of a bypass with the suggestion of utilising elements of the old highway Bacup Old Road.
