|Route outline (key)|
The A578 is a rather short A-road which heads northwesterly from the Lancashire town of Leigh. Running through an area of near-continuous, mostly terraced housing, it is subject to a 30 mph speed limit throughout.
Starting just south of the bus station at a light-controlled junction with the A572 / B5215 King Street and heading first westward along Twist Lane, the route intersects the A579 at the site of the former Parsonage Roundabout (since autumn 2013 a signalized "semi-hamburger junction").
Some 250 m further on, the A5078 TOTSOs to the right into Wigan Road by the Firs Lane post office. From this point, the A578 heads generally north-by-northwestward. After about a mile, we reach a mini-roundabout known locally as The Tamar, after the pub on the corner of the junction. From here, the route turns slightly more north-westward before shortly reaching a set of traffic lights (installed in June 2009) where the B5237 terminates, coming in from the left.
The final section of the route takes us in a generally north-by-north-easterly direction along Leigh Road to meet the A577 in Hindley Green, where – at a light-controlled T-junction known locally as The Bethel (after the church / former community centre that faces the end of the A578) – our journey comes to an end.
