Notes
In order to keep the arch springings outside the water, the design extends the structure below water level with struts creating a theoretical span length of 416 meters for the longer span. To counteract creep and shrinkage effects, the arch was raised using jacks by 63 mm after two years of service and by an additional 93 mm after another year. The jacks were then encased in concrete.
