The New Brunswick government plans to spend $1 million to install rock along the Petitcodiac River in Dieppe.
About 20,000 tonnes of rock, known as riprap, will be placed along the riverbank between Wheeler Boulevard and Virginia Avenue starting in June.
The province says the work is a result of ongoing monitoring of the river following the opening of the causeway.
“In this case, the Dieppe dike showed signs of erosion and it was deemed necessary to repair it to protect the trail and commercial area located behind it,” Jacob MacDonald, a spokesperson for the province’s Department of Transportation and Infrastructure, said in a statement to Radio-Canada.
The causeway built in the 1960s blocked the tidal flow of the river.
