Preston is at the centre of a massive motorway network, which is good for logistics and commuting- M6/M55/M61/M65.

However, if you want to get from one side of Preston to the other, it narrows your options - you have to go through town, leaving Strand Road, Garstang Road and Walton-le-Dale congested.
