Look at the M25, it took them almost 30 years to open the Cobham services. Before that opened the whole of the west side had no service area, you could go round half the motorway from the M23 to the M1 without passing a single service station.
When South Mimms opened after the M25 ring was completed there was a sign for the services on the A1 southbound.
It said something like:
Services: Eastbound 28 miles.
Westbound 90 miles.
The point being the sign referred to the same services.
