The Alaska Highway between Fort Nelson and Prophet River is expected to be open in both directions by 3 p.m. PST.

Fort Nelson RCMP say the highway was closed after one semi tractor trailer rear ended another. Police say poor weather conditions, including blowing snow, were probably a factor in the crash.

The truck that rear ended the other began to leak radiator fluid because of the damage to its engine.

The highway is currently open to alternating traffic as an environmental team is on scene cleaning up the spill.
