The first of the heavy trucks heading into Wellington from Seaview are now approaching The Terrace tunnel with the tail back at the Ferry Terminal.
Trucks heading in from SH1 are a few minutes away from Ngauranga Gorge stretching back to Churton Park.
General commuter traffic is travelling well. Wellington Police are impressed with the way motorists are responding.
People have anticipated delays, planned for them, electing to leave home extra early to reach work or have looked at alternative travel.
