THE two old timber bridges on Pitt Town Road, Maraylya, are expected to be replaced by mid to late April.
The original finish date was the end of March.
The completion date was delayed for two reasons, The Hills Council’s infrastructure projects manager Ken Willimott said.
He said excessive rain in February was one reason.
The other was that the approving authority for a special permit needed for an oversized truck to bring planks to both bridge sites changed from the NSW to the federal government mid-project.
“What we’re now doing is widening the approach roads and putting the finishing touches on the bridge decks,” Mr Willimott said.
Reinforced concrete planks have been installed at both sites.
‘‘We have utilised very high strength steel tendons in the planks, allowing them to span longer distances much more efficiently,’’ Mr Willimott said.
‘‘An extensive amount of environmental work had also been done around the site.
“We lined the creek with rocks to stop erosion and protect the bridges – but they also provide a habitat for native, aquatic species.
“We’re also planting around 6000 native plants around the site.”
The Hills mayor Michelle Byrne said the replacement of timber bridges was a priority for councils throughout NSW.
‘‘This project is something to be proud of,” Cr Byrne said.
