The surface of the N03 between Zurich South and Reichenburg is old and showing signs of damage, and should be repaired before the next set of major measures are implemented under the Road Maintenance Plan (UPlanNS for short). The rehabilitation of the road consists of 4 sections of the main route including the acceleration and deceleration lanes and the repair of the most urgent damage to engineering structures.
The most immediate maintenance measures were implemented in 2013 while the main works took place in 2014.
