Traffic woes with construction underway on Dunlop Street bridge replacement

Construction on the Dunlop Street bridge over Highway 400 has created traffic disruptions that are expected to last for quite a while.

Motorists have to pack their patience as construction to replace an aging bridge over Highway 400 in Barrie has created traffic disruptions and delays.

Ministry of Transportation crews have started work on the existing two-lane Dunlop Street bridge, with construction spanning from Hart Street to Cedar Point Drive.

The City warns there will be intermittent traffic disruptions over the coming weeks through the area, adding traffic would “generally be maintained” along Dunlop Street throughout construction.

The scope of the project includes replacing the bridge with a longer overpass to accommodate future widening of Highway 400 to 10 lanes. At the City’s request, the new bridge will also be wider to help improve traffic flow.

The entire project is anticipated to be completed by fall 2028.
