An image of how the Third River Crossing in Great Yarmouth will look. - Credit: Norfolk County Council Work on a third bridge across the River Yare in Great Yarmouth is due to begin next month - bringing some temporary traffic measures to the town. Last month, the government approved funding worth £98m for the long-awaited Third River Crossing linking the A47 at Harfrey’s roundabout to the port and the enterprise zone on the other side of the river. It is hoped the bridge will support economic opportunities in the wider borough as well as ease congestion in the town.
