|Route outline (key)|
The A668 is a defunct road in south Lancashire.
Back in the day, it started on the A56 in Whitefield then headed northwest to Radcliffe, where it crossed the River Irwell. Heading more northerly, it passed through Black Lane to end on the A58 at Ainsworth Lodge.
When the A665 was extended northwards in the 1960s it took over the A668 as far as Radcliffe, before taking a longer route to the A58, reaching it closer to Bolton. This removed the A668 from the map, as the remainder was downgraded to Class II status. The short section left in Whitefield became the B6473 whilst the longer section from Radcliffe to Ainsworth is now the B6292. Radcliffe town centre has been bypassed in more recent years.
