MOTORISTS and pedestrians around Wynyard station in the city will face disruption from next month when the state government begins construction of walkways between the station and Barangaroo.

The NSW Minister for Transport, Gladys Berejiklian, said yesterday work would begin on a 110-metre underground pedestrian tunnel and a 100-metre bridge crossing Sussex Street in October. The entire project would cost about $300 million.

However, she said work would begin next month to widen footpaths along York and Margaret streets in preparation for the closure of the Kent Street tunnel in October. One eastbound traffic lane would also be removed from Margaret Street.

The new infrastructure is designed to let people walk from Wynyard station to Barangaroo in six minutes.
