The remaining cross beams were erected in the river channel at the end of May, and the longitudinal beams are now in place so there is a continuous span
across the river.
But contrary to the impression it makes at Badaling, the Great Wall may never have crossed China in one mighty, continuous span
, nor is its length precisely known.
Modeling of the cable as a discrete parabola in different spans does not hold true in continuous span
structures as this creates discontinuity at the juncture of different spans.
Because the hanging section was a part of the continuous span
, its movement could damage the rest of the bridge.
Newell Porcelain briefly suspended operations the end of August, breaking a continuous span
of more than 50 years manufacturing solid core station and line post insulators.
The existing structure, five continuous spans
, was constructed in 1961.
Stanley Karnow, an American journalist and historian, wrote in his 1989 Pulitzer Prize-winning book, "In Our Image, America's Empire in the Philippines," that: "Despite its modern trappings - [the Philippines] was still a feudal society dominated by an oligarchy of rich dynasties, which had evolved from one of the world's longest continuous spans

Engineer James Parsons said: "The main portion of this bridge has three continuous spans
but only two trusses in its cross section, which means that if a part of one truss fails the whole bridge will come down.
James Parsons, a fellow of the Institution of Structural Engineers, said: "The main portion of this bridge has three continuous spans
, but only two trusses in its cross section, which means that if a part of one truss fails then, as there is no redundancy, the whole bridge will come down.
In closing, it is important to note that this seemingly simple transformation of simple-span prestressed girders to continuous spans
should be attempted with caution, and significant attention must be paid during analysis and design to include loading conditions that can cause counterintuitive behavior such as secondary positive moments at the piers.
