Line and meets the B5257 at a roundabout. It meets the B6230 at a roundabout at Dog Kennel Wood, crosses the River Darwen and meets the A675 at Walton-le-Dale, where the bypass ends. The A6 crosses the River Ribble and the Ribble Way, entering Preston district. It enters Preston as a single carriageway, meeting the A59 (for Blackburn), B6243 (for Ribbleton), and A6063. It passes through the centre of Preston, becoming North Road, meeting the A5071 (Moor Lane), then becoming Garstang Road. The A6 passes Moor Park and crosses the A5085 Blackpool Road. At Fulwood, it meets the B6242 at crossroads, then passes Sharoe Green. North of junctions with the B6241 Preston ring road, junction 1 of the M55 is a roundabout on the A6 connected by slip roads with the motorway above. This was formerly the northern end of the Preston bypass. After the motorway, a bypass opened in 2017 takes the A6 east of Broughton, where it formerly met the B5269 at crossroads; the bypass, James Towers Way, is dual carriageway as far as the roundabout where the roads now cross, and meets the former A6 at another roundabout. Through Barton, still as Garstang Road, it runs along the Preston and Wyre district boundary, converging with the West Coast Main Line and crossing the railway on a bridge. The district boundary crosses to the other side of the road and it enters the Borough of Wyre. It passes through Bilsborrow before leaving the district boundary, crosses the River Brock at Brock, and passes the site of a former railway station; a bridge carries the road over the Lancaster Canal. At Catterall, it meets the B6430 – the original A6 route – and crosses the River Wyre, and as Preston Lancaster New Road meets the A586 (for Churchtown). It enters Garstang and crosses the Lancaster Canal again. It meets the B5272 and B6430 – the original A6 coming back to meet us – and enters Cabus. At Forton, it passes close to the Forton service station on the M6. At Potters Brook, it meets a crossroads and enters the City of Lancaster. It meets the M6 at junction 33 and goes through Galgate as Main Road, passing under the West Coast Main Line, which it then runs adjacent to. The University of Lancaster lies in the separation between the A6 and the M6, where there is a short section
