As part of the Tintenbar to Ewingsdale upgrade of the Pacific Highway, the old Bangalow Road over bridges are being replaced with roundabouts.
The southbound bridge was removed some months ago. This week the northbound bridge is coming down.
Demolition of the bridge took place overnight on Monday with Bangalow Road closed until early this morning.
Both north and southbound traffic on the Pacific Highway is being diverted via the new southbound roundabout.
Work will continue throughout the week with controlled stop/slow roadworks continuing on Bangalow Road.
