PROBLEM TO BE SOLVED: To provide a telescopic temporary pathway which length is adjustable corresponding to a space between pathway installation parts apart from each other. SOLUTION: The telescopic temporary pathway 10a comprises a main frame 13 consisting of two hollow beam materials 11 parallel to each other and two horizontal rod materials 12a, 12b via which the hollow beam materials 11 are connected to each other at both ends and on which a scaffold plate is mounted, and a main engaging hook 15 provided at one end of each of the hollow beam materials 11 for engaging with one pathway installation part. The telescopic temporary pathway 10a also has a sub frame 18 consisting of two sliding rod materials 16 to be reciprocatingly inserted into the hollow beam materials 11 at the other end sides, respectively, and a connection rod material 17 via which the sliding rod materials are connected to each other at their protruded side ends and on which the other scaffold plate is mounted between the horizontal rod materials 12a at the other end sides, and a sub engaging hook 19 provided at the protruded side end of each of the sliding rod materials 16 for engaging with the other pathway installation part.
