A walkway extension assembly for a paving machine has main and laterally extendable and retractable screeds and a transversely extending rear catwalk or walkway. The assembly has a laterally extending walkway component extending beneath and on each side of the existing walkway. Channel members are attached to and extend downwardly from bottom surfaces of the existing walkway. The lateral walkway components are positioned beneath the existing walkway on these channel members, and are slideably extendable, laterally and outward from the existing walkway. Brackets are attached between the ends of the walkway components and the sidewalls of the lateral screeds. By this configuration, when the lateral screeds are extended from beneath the paving machine, the lateral walkway components, moving in tandem with the screeds, are also extended. Workers are thus able to stand on the walkway components, outboard of the paving machine itself, to observe the lateral paving operations.
