Yep, the town planners have been at it here for some years.

Example:
In Great Yarmouth, about 16 miles from me, you arrive at a traffic-light intersection on a one-way street. The cross street is also one-way, running to the left, and making aleft turn there it's only about 200 yards to one of the main roads to head out of town. But there's a "no left turn" sign there, so you instead have to go straight over the lights, right up to middle of the town in amongst the congestion of taxis, buses, etc. then loop around to eventually arrive back at the same intersection where this time you go straight across. It adds about 3/4 mile through the most congested part of the town. [Linked Image]
