Members of the public are checking out Kapiti Coast's new $630 million expressway on Saturday before it opens to traffic in the next two weeks.
The long-awaited stretch of four-lane highway north of Wellington is open to the public from 10am until 3pm.
People can walk or bus five kilometres of the 18km expressway between Te Roto Drive in Paraparaumu and Te Moana Road in Waikanae.
The "ExpressDay" route is open to pedestrians and mobility scooters and wheelchairs on one side and tour buses on the other side.
The expressway links McKays Crossing to Peka Peka, bypassing several small towns that have slowed down traffic on State Highway 1.
Transport Minister Simon Bridges opened the expressway on Thursday, saying it will significantly improve safety and cut down travel time. It opens to traffic in the next two weeks.
It has 18 bridges, construction put more than $200m into the local economy, more than 5000 people worked on it and 3.5 million cubic metres of earth was shifted.
Paraparaumu sewer outlet unstable
Meanwhile, Kapiti Coast District Council is monitoring a sewer outlet at Paraparaumu Beach after a wall protecting it moved.
A 170m temporary block wall was installed at the sewer main serving properties on Wharemauku Road following a big storm in August.
A portion of the blocks along the central section of the wall have recently rotated towards the sea, the council says.
The situation is being monitored during the weekend.
The council's staff, contractors and engineering consultations have assessed the wall and say there is no immediate danger of it collapsing, says Sean Mallon, the council's group manager of infrastructure services.
"We are currently planning on doing a further assessment on Monday to determine the extent of any repairs or remedial works required," he says.
"In the meantime, we're installing barriers and signage alerting the public to the potential instability of the concrete blocks and restricting access along the reserve area behind the wall."
