The new Taipa Bridge on State Highway 10 in Northland has opened to one-lane traffic.
First across the bridge on Friday was truck driver Darren Rupapera, from Kaitaia, who was on a routine delivery run.
"I come through Taipa just about every day and this will be a great improvement. It's a great day for Northland," Rupapera said.
"When they told me I was going to be the first to drive over the new bridge I was so excited. It's something I'll always have to tell my mokopuna. Man, it's an honour.
"The old bridge is closed to traffic but the pedestrian footpath on it will remain open.
