Is it the G4 Beijing-Hong Kong-Macau Expressway?
Noooo
The world's longest traffic jam on Highway 110 near Beijing?
Is that the one that was 8 miles long and people were ordering food to be delivered to their cars?

On the Beijing - Tibet Expressway near to Beijing. Apparently trucks carrying coal and construction supplies to Beijing were prevented from leaving the motorway causing the jam, apparently 62 miles long, lasting 12 days - insane !
Yes got it... over to you
It was actually over 60 miles long and lasted over 10 days!

Clue needed please
There was the Anglo-Scottish cup tie in 1987-88 between Coventry and St Mirren where the first leg was played, but the competition was scrapped before the second leg. (Forest in 1959 was the big clue, so I wondered if Cup winners had something to do with it).
