bearing members 5 have a length slightly less than twice
Existing railroad and highway traffic crossings are
commonly constructed of traffic bearing members rigidly 15 the distance between the center-lines of adjacent ties 3 so
that each tra?ic bearing member 5 has its opposite ends
secured to the railway cross-ties. Timbers spiked or
fastened by screws to the track ties furnish an example
of crossings of this character. In such crossings, the
connections between the timbers or other traffic bearing
members and cross-ties frequently tear loose due to the 20
pounding of heavy rail and highway tra?ic. The result
is frequent expensive maintenance and rough crossings to
highway vehicles.
One of the objects of this invention is to provide a
5a supported by one of the saddle structures 6, and each
tra?ic bearing member 5 straddles an intervening tie 312.
Each of the saddle structures 6 comprises a central saddle
part or member 6a extending between the rails 1, and a
pair of end saddle parts or members 6b that respectively
project laterally outwardly in opposite directions with re
spect to the rails 1. The saddle members 6a and 6b in
each saddle structure 6 extend longitudinally with respect
