A bridge in St. Adolphe, Canada is to remain closed indefinitely as one of its support piers sinks into the river bottom.
Officials say the Highway 210 bridge over the Red River has become dangerous, with a possibility that it could be susceptible to collapse.
Manitoba Infrastructure and Transportation executive director of construction and maintenance Ron Weatherburn revealed that until the pier stops sinking, it will not be known whether it will need to be repaired or replaced completely.
He said: “We don’t know exactly what will happen at this point.We won’t know until we see what happens.”
Last week, inspectors noticed a pier on the bridge had sunk a metre into the river bottom. Since then it has continued to sink.
Weatherburn said slope instability - likely to be caused by spring flooding - may be to blame, although the theory is unconfirmed at present.
Concrete barriers are in place to block access to the bridge and security has been stationed there around the clock.
