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 already see the tailback not far from the sliproad exit J40, so I just turned of and followed the flow of trafic until it went onto the A11. I pulled in on a parking place and checked Google Maps on my mobile, and found a nearly straight jurney to J37. As you can see just a little d-tour of 15.6 Miles.
