Waka Kotahi is warning Transmission Gully between Pāuatahanui and Paekakariki will be closed for some time due to a fuel spill.
A fuel tanker and another truck crashed before rush-hour this morning.
Eight fire-tracks have been in attendance.
Drivers heading in and out of Wellington are warned to expect lengthy delays, with heavy congestion on alternative routes.
