PROBLEM TO BE SOLVED: To provide a bridge segment constructing machine which eliminates the necessity of a large size girder for the construction in a large span interval, can perform construction for the large span interval even if an interval which the girder could not reach is left not constructed, can turn round the construction direction at will, can move the girder skipping an interval left not constructed can perform construction even if a building exists close to a curved interval and can perform construction without making large girder reaction work on a bridge body. SOLUTION: This bridge segment construction machine includes a pair of guide arms 18-1 and 18-2, which has length enough to be constructed between a bridge piers 1-2 and 1-3 and moves in an axial direction, and a bridge segment construction girder 7, which moves on a pair of guide arms. Then, mechanisms which are connected to and separated from each other at any angle in a horizontal face, are provided on the end sections of a pair of guide arms, and the bridge segment construction girder 7 moves along a pair of the guide arms, and a bridge is constructed with bridge segments are connected between bridge piers.
