RCMP have reopened Highway 40 south of Grande Prairie after it was closed earlier Friday over fears about a sour gas leak.

Emergency crews were sent to the well located in a sparsely populated area about 110 kilometres south of Grande Prairie

Police were told about a potential leak of H2S around 2:45 p.m. Friday so the highway was closed south of the Canfor Cut Across, about 50 kilometres north of Grande Cache.

The Energy Resources Conservation Board (ERCB) has since told police that the incident poses no threat to public safety in the area of the road closure so it was reopened.
