PROBLEM TO BE SOLVED: To provide a sleeve for use at a viaduct bearing part, which dispenses with work of forming a sand mound and work of scraping out the sand mound for removing the same, and contributes to improved workability, and to provide a method of constructing a viaduct bearing part using the sleeve. SOLUTION: The method of constructing the viaduct bearing part which bears a lower structure-side abutment 1 and an upper structure-side girder portion 2 in a manner ensuring movability, by using the sleeve, is composed of: a step of inserting a sleeve portion 3a of the sleeve 3 with a flange into a bearing hole 2a from a lower surface of the girder portion 2 to fix the sleeve 3 with the flange to the girder portion 2; a step of inserting a rod-like shaft portion 4 of the abutment 1 into the bearing hole 2a formed in the girder portion 2 and the sleeve 3 with the flange; and a step of filling a gap between the bearing hole 2a and the sleeve portion 3a with mortar.
