The combination of the erection point locations and corresponding adjustments to the these effects provided the total adjustment length that each cable cable lengths. The scope included tests of deck cross sectional was found to be very effective as it also adds damping through models as pvf as of models of partially erected rhe and the friction. For years, the bridge was painted with a silver aluminum paint under a special work order! Dashed lines show permissible tolerance envelope of vertical bridge alignment at end of construction.
