New Brunswick Liberal Leader Shawn Graham says his party would put up 300 kilometres of highway fencing to help prevent vehicle collisions with wildlife, especially moose.

Graham said on Monday that fences would be put up within two years if the party wins the next election.

The fences would be in areas with a high moose accident rate.

Graham anticipates the project would have a price tag of upwards of $21 million, but he said it would be money well-spent.

"Any accident that is prevented and any life that is saved is taxpayers' dollars worth investing in," he said. "It's an investment in safety and security."

Transportation Minister Paul Robichaud has acknowledged that more fencing is required and said he'll announce a full policy next month.

There are more than 250 moose-vehicle collisions on New Brunswick highways every year.
