The Met will be closed during the lunch hour on Wednesday and Thursday while crews inspect the roadway at the site of a deadly crash.
A section of the elevated highway was damaged last month when a truck smashed into a vehicle that had stopped in the middle lane.
The driver of the truck, Gilbert Prince, was trapped in his cab and died in the fire.
Construction crews raced to reopen the highway in both directions, but they skimped on some of the repairs.
Now crews will inspect the roadway to determine what else needs to be done, such as painting the lanes and installing permanent barriers.
One lane of westbound Highway 40 will be closed at the Christophe Colomb exit between 11 a.m. and 1 p.m.
In case of bad weather the work will be delayed.
