Motorway gantry sign
A gantry spanning the motorway with blue overhead signs showing the following text.
Forward destinations: NORTH WALES, Birmingham; Chester, Runcorn, M'cr (S & [Airport symbol]) (M56) M6 .
Exit destinations: A50 Macclesfield, Warrington (S); B5158 Lymm.
Junction number: 20.
Junction 20 is a two-parter - we'll meet the M56 in a minute and that will be part of the junction 20 complex as well. But our first business is this exit which leads to Lymm, a town without any vowels.
