Leeds Inner Ring Road Starts Here. Use of varying thickness of continuous line, overs and unders. Pre dates Spagetty Junction near Birmingham. Mick Burton, 1967.
The new inner ring road was announced and a board went up telling us about it, along with a plan. I exaggerated it in my picture with many Overs and Unders. This was several years before Spagetty Junction near Birmingham.
