M1
From Tardis Wiki, the free Doctor Who reference
The M1 was a British motorway opened in 1959. It had a service station called Blue Boar services.
The Eleventh Doctor and Amy Pond visited the M1 shortly after it was opened, because the Doctor wanted to see it "before they messed it up". Here they had an encounter with Petrolions. (COMIC: Madness on the M1!)
