Motorway gantry sign
A gantry spanning the motorway with blue overhead signs indicating two lanes exiting and three continuing ahead, and the following text.
Left-hand two lanes destinations: A1(M) The SOUTH; (M62) Hull.
Right-hand three lanes destinations: London, Leeds M1; Manchester (M62).
Junction number: 43.
Change Route: A1(M) The SOUTH
The motorway divides here into the A1 to the South of England and London and, er, the M1 towards the South of England and London.
The main line of the motorway actually heads to the M1, so if you want to stick with the A1 on your journey south you need to exit now.
