VANCOUVER - Enbridge Inc. says it has begun construction of a temporary access road to the site of a natural gas pipeline explosion near Prince George, B.C.

In a news release issued Sunday the company says construction will take a few days, but it has no timeline on when the repair work will be completed.

An explosion Tuesday knocked out a 91-centimetre line and another pipeline is supplying natural gas on a reduced basis.

Enbridge says it has completed soil sampling and preliminary field observations in the area of the blast and found no traces of hydrocarbons in the soil.

It also says field observations show that animals and plants are still active and viable around the explosion site.

Enbridge says it expects the site to recovery quickly.
