Sydney retailers face their second – and some their third – Christmas of disruption from construction of the $2.1 billion light rail line.

And, near the two-year anniversary of the start of construction, they fear the disruption along much of George Street in the CBD, and other parts of the line, will extend well into next year.

Construction on a stretch of George street between King and Market streets was originally due to be finished in August last year but retailers, such as cosmetic store Jurlique, doubt it will be finished in time for Christmas, their most important trading period of the year.

Jurlique manager Ellie Yu said pedestrian traffic outside her store had dropped significantly this year, hurting sales.
