NAWIC Scotland enjoyed their site visit to the Raith Interchange on Friday 30 September 2016.
The complex works to create an underpass below the existing roundabout, providing a free flow link for traffic between the Bellshill Bypass and the East Kilbride Expressway were very impressive. The site constraints are significant with the construction of three new bridges to carry the motorway and local traffic over the underpass all whilst maintaining existing traffic flows. The level of the underpass is below the water table, with the River Clyde flowing close by, and the underpass road formation is anchored to rock to prevent it “floating” during rises in the water table. This together with the existing traffic requirements has resulted in complex sequencing of the works as well as 24 hour working. We were guided through the compact site and saw some areas of the underpass were still under excavation whilst others were nearing formation level. A very interesting technical visit and our thanks go to the CJV team and Transport Scotland for facilitating our event.
