Motorway gantry sign
A gantry spanning the motorway with blue overhead signs showing the following text.
Forward destinations: The SOUTH, Birmingham; Manchester (M61), Liverpool (M58) M6 .
Exit destinations: A59 Preston & Clitheroe.
Junction number: 31.
This is Samlesbury Interchange, the original junction on the original motorway. But like the Preston Bypass itself it's been so completely rebuilt you'd need an archaeological dig to find the original parts now.
