Motorists won't be driving on the Des Chenaux overpass on Highway 40 in Vaudreuil Dorion anytime soon.
The transport department initially closed the bridge in September following safety concerns.
The overpass was hit by a truck last June and an inspection found problems with the load bearing capacities of the overpass.
A new evaluation shows major repairs are needed before the structure can be re-opened to traffic.
The ministry is looking at its options and expects to make a decision on a solution by the end of the fall.
In the meantime, detours are in place and drivers are being told there is no danger to use the highway beneath the overpass.
