Highway 174 Montreal Road Interchange Bridge Construction

Project Status: 

Highway 174 Montreal Road Interchange Bridge Construction


In 2020, a critical component of the Stage 2 Confederation Line East Extension will be constructing two new bridges at the Highway 174 Montreal Interchange.

Montreal Station will be located above Montreal Road within the median of Highway 174. This requires two new Highway 174 bridges and a reconfiguration of the interchange to shift ramps, traffic, utilities and multi-use pathways away from where the future station will be located.

Ongoing Work 

Work is currently underway on Montreal Road in between the eastbound and westbound highway ramps. Starting April 10, Montreal Road traffic will be reduced from two lanes in each direction to one lane in each direction under Highway 174.

Montreal Road north side lanes will be closed to accommodate the work zone, and south side lanes will be used to accommodate bi-directional traffic. All ramps will remain open, however one left turning lane on the HWY 174 eastbound off ramp will be closed

Two lanes on the north side of Montreal Road will be closed to accommodate bridge construction. Two lanes on the south side will be repurposed to accommodate bi-directional traffic. Highway 174 ramps will remain open, however, one left turning lane on the eastbound off ramp will be closed

The multi-use pathway on the north side will be closed, with pedestrians and cyclists directed to the new widened pathway on the south side.


Lane reductions on Montreal Road under Highway 174 will begin in April 10 2020 and lasting through summer 2020.

Work will occur during daytime hours with overnight work required at times. A City of Ottawa Noise By-law Exemption is in effect.


All pedestrian, cycling and vehicular access will be maintained, and directional signage will be in place. Pedestrians and cyclists should use extra caution as traffic patterns change. Moderate delays to vehicular traffic may occur at times. Motorists may wish to allow for a little extra travel time, and should adhere to traffic control signage, posted speed limits and instructions of traffic control personnel.
