Gallery:B197
On the left hand side of this picture you can see where the present B197 Welwyn Bypass (ex A1) crosses over the present A1000 (ex B1000). The bridge was built in 1927, according to the engraving on the side. A look at an aerial photo shows that this junction was a partial cloverleaf, but these days, priorities have changed, and what was once the westbound to southbound 270 degree loop is now a right turn for southbound to westbound traffic - the bridge spans one leg of a gyratory now.

These days, the A1000 continues round to the right, with a local road going into Welwyn village, but when first built, the right hand of the fork would have operated in reverse, allowing northbound traffic to turn east along the (then) B1000 towards Digswell.

The no-entry indicates where the westbound A1000 joins the roundabout, and the right turn is where the eastbound A1000 leaves the roundabout. The roundabout is situated where the north end of the loop roads would have ended up.
