State Highway 1 was closed for 45 minutes this morning because of a collision involving three cars and a truck, between Lindale and the Paraparaumu overbridge.
The Transport Agency advised at 9.45 that the highway was closed in both directions at Lindale.
It said a detour was in place. But it warned that drivers should expect delays and take an alternate route if possible.
At 10.30 things had improved: Both lanes on State Highway 1 at Lindale were open, but due to a clean up there were more delays.
By midday, the cleanup was completed and the road was back to its normal condition.
