In December, 91原创 Township approved spending up to $1 million to shore up the winding road where 56th Avenue crosses the Salmon River.

鈥淪lope stabilization works are urgently required in order to stabilize slope movement that is causing pavement distress and slope instability,鈥� a Township engineering report warned.

鈥淭he slope analysis indicated that the slope is marginally stable under static conditions and likely unstable during a large magnitude seismic event,鈥� the staff report said.

In the 24200-block of 56th Avenue, the road descends abruptly and snakes down to cross the river, rising rapidly again on the opposite bank.

There have already been multiple repairs and upgrades to the road during the past 20 years, including new retaining walls, but cracks and sinking pavement have continued to be an issue.

In response to an Advance Times query, a Township statement said the total project cost was expected to be approximately $910,000.

鈥淭otal final project costs will not be known until after the project is completed,鈥� the statement advised.
