A skidding system is provided for laterally moving a catwalk. The system can include a plurality of legs placed about the perimeter of the catwalk. Each leg can extend and contract in length. The lower end of each leg can include a trolley member slidably coupled to a foot assembly. The catwalk can be moved laterally by extending the legs to raise the catwalk off of the ground, moving the trolley members within the foot assemblies and then contracting the legs to lower the catwalk to its new position.
