Although this is a modern photo by Jim Brown, the tunnel itself dates from 1967. This co-incides with the opening of the Crossbasket stretch of the A725 East Kilbride Expressway, leading up to East Kilbride. The tunnel permits water coming off the upper Southern slopes of Blantyre to safely travel under the expressway heading back into the Calder.
In October 2011, my little dog ran off from a walk in Greenhall, spooked by the Council’s leaf blowing machine. He was found 24 hours later thankfully due to the name tag and telephone number, arriving on the doorstep of a property at Calderside. I was stunned that he had traveled a mile and a half up the hill and even more so over a busy expressway. Upon reflection, after seeing this photo, he likely went through this tunnel rather than crossing a busy dual carrigeway, as he’s very fearful of cars in general.
On social media:
I remember sitting at Basket Road watching sections of the tunnel being put into place during the summer of 1965. I have at home an aerial photograph from 1965 of the area and you can clearly see the ground works from the River Calder to where the expressway originally terminated at Greenhall.
