The air seeder unit that struck an overhead road sign on Main Street North near the Highway 1 overpass on Tuesday afternoon remains stuck.

Two cranes are currently on the scene of the incident trying to free the farm implement from the sign. 

The northbound lanes of Main Street North remain closed at the Diefenbaker Drive intersection as of 9:30 a.m. on Wednesday. There is no timeline for when the road will re-open. 

Traffic is being detoured onto Diefenbaker Drive. Police are asking motorists to avoid the area as the highway will be blocked for an unknown amount of time.
