The route I'm talking about is High Barnet, Elstree, Watling Street up to St Albans, and then across to Hatfield, Potters Bar, and back to High Barnet.
I often cycle this route as it's quite a good distance, quite pleasant, and nice and straight in places to build up some good speed.
When I was cycling the route last weekend, and I came up to the roundabout where the M10, Watling Street and A414 all intersect, I noticed a "Cycling forbidden" sign on the exit from the roundabout on the continuation of Watling Street up to St Albans.
I found this odd because the sign was on the exit to the roundabout.
I was just wondering if there might have been any recent accidents involving cyclists in this area that would have prompted the local authorities to put a sign up such as this.
Thanks.
