The works being carried out by Scottish Water on the main route between Carluke and Lanark, the A73, will resume tomorrow (Tuesday) following a break over the festive season.
The utility company began the major pipe replacement on the stretch of the road near Cartland Bridge late last year, imposing light-controlled single lane traffic on what is one of the busiest stretches of highway in Clydesdale.
The news of the extensive and disruptive works raised complaints from the business community in Lanark, fearful that it would impact on their busiest time of the year and discourage visitors coming to the town to attend events like the annual Christmas Market.
However, after representations, Scottish Water agreed to suspend the works over the festive season and that `truce’ came to an end on Tuesday.
The works are expected to continue for two months.
