Continuous travel track on a viaduct structure

A continuous running track to be supported by a bridge structure having at least two bridge segments and a load-bearing structure for supporting the at least two bridge segments, the continuous running track comprising:

• a continuous slab extending from one end of the bridge structure to another end of the bridge structure and configured to rest on an upper surface of the at least two bridge segments;
• an antifriction layer disposed beneath said continuous slab and configured to act as an interface between the upper surface of the at least two bridge segments and a lower surface of said continuous slab, said antifriction layer defining a slip plane for said continuous slab;
• a crossing plate disposed beneath said continuous slab and positioned to extend from an end of one of the at least two bridge segments to an end of another directly adjacent one of the at least two bridge segments;
• and
• at least one anti-lift device configured to be fixed to one of the at least two bridge segments, for limiting a movement of said continuous slab in a direction substantially perpendicular to said slip plane but providing for freedom of movement of said continuous slab on said slip plane.
