Apparantly the big news in the Westcountry is that the A303 is to be closed some time early next year, with a 40 mile diversion. The BBC has more details and the Highways Agency press release is also available.
I wondered why neither the HA nor any of the press articles I’d seen bothered publishing a map. While they’re happy to describe an elaborate route in text, it took me less than five minutes to knock this up.
The visual view is – I think – much more explanatory than any text, and it adds instant impact to the article.
