The A47 has reopened after "human waste" was spilt from a lorry across the carriageway.
Drivers and bus services had been hit by heavy delays throughout the afternoon following the sewage spill this morning (October 18) in Hockering.
Police closed part of the A47 towards Dereham after the incident which happened at about 8.50am.
Bus companies warned passengers that services are facing long delays and some journeys have been cancelled.
Due to the "severe" impact to passengers, First Bus and Konectbus are accepting each other's tickets for journeys between Dereham and Norwich.
A police spokeswoman said: "The clean-up operation continues to be underway and emergency services remain on scene.
"It is hoped that the road can reopen in the next two hours in time for rush hour traffic."
As of Tuesday night, Highways England confirmed the section of the A47 reopened.
