The present invention relates to a transition structure 10B for bridging a structural joint 14 between two structure parts 12 and 12b of a structure 12. The transition structure 10B has at least two trusses 16 mounted on the edges of the structure and at least one slat 20 displaceably mounted thereon, wherein a primary sliding surface 22 is arranged between at least one truss 16 and at least one slat 20. The primary sliding surface 22 has at least two partial sliding surfaces 22a and 22b, which are each arranged in mutually angled sliding planes 34a and 34b, the sliding planes 34a and 34b meeting in a common line of intersection S which forms an axis of movement A along which the slat 20 can move relative to the truss 16. In this regard, at least one sliding plane 34a, 34b is arranged at an oblique angle to a plane of movement B of the transition structure 10B.

A rail splice plate kit comprising first and third rap holes that align with first and third rail holes on a first rail to be spliced, second and fourth rsp holes that align with second and fourth rail holes on a second rail to be spliced, and the first, second, third, and fourth rsp holes are substantially circular. The rail splice plate kit comprises four rail bolts which have a cross section that is within 1/16 of an inch of a diameter of the first, second, third, and fourth rsp holes. The diameter of the first, second, third, and fourth rsp holes may be no more than 3/64 larger than the cross section of the rail bolts. The rail splice plate and the bolts are formed of steel. Adjacent rsp holes are spaced 5 inches from center from one another and a cross section of the rail splice plate is arcuate.
