Pinched Camelback

In the 'states, when a Pratt truss is slightly higher in the center than the ends, its nickname is camelback truss. This bridge, which connects the library island with the science museum, is much more advanced than a Pratt truss, what with its all-welded, tubular steel structure, but one can still see a little resemblance. Furthermore, the narrower top makes it look more like a camelback than an actual camelback truss. Actually, this appears to be a mashup between a truss and a tied arch bridge.
