Just a little detour

I was on my way home from Colchester via the A14, and the overhead warning said that the A14 was closed between Junction 37 and 39. When i got near Junction 40 I could see the tailback not far fron the sliproad entry of J40, so i just went of at J40 and followed the trafic until it went onto the A11, ten i pulled in on a parking and checked on my mobile Google Maps, and found a nearly straight link to J37.
