Two lanes are currently closed between junctions 31 (A59 Preston New Road / Samlesbury) and 31a (B6242 Bluebell Way / Longridge). A lorry has shed some of its load of sawdust after breaking heavily to avoid a collision just before junction 31a. The scattered debris led to the closure of lanes 1 and 2, causing congestion back to junction 29 (M65 / Lostock Hall) and junction 9 of the M61 at Walton Summit. National Highways reported delays of around 60 minutes while Lancashire Police said it expects the partial closure to remain for a few hours whilst the cleanup continues.
