	As the erection of large arch bridges is very difficult, they have virtually been ruled out since the appearance of cable-stayed bridges. Hence only one example is given.

ANGOSTURITA BRIDGE OVER RIO CARONÍ
AT CIUDAD GUYANA, VENEZUELA
(1979)



	H14. Model.


	Six-lane highway and double-track railway bridge, span 280 meters, height of arch 50 meters. Bridge deck with total width of 33.8 meters, consisting of a central box girder, width 12.0 meters, depth 4.0 meters, and an orthotropic plate. Central arch with width of 5.0 meters and depth of 2.9 meters, bifurcated at deck level in order to give way for the railway. Inclined hangers of parallel-wire cables in order to reduce bending moments in bridge deck and arch.


	Proposal for design and construction competition.
