Quebec construction sites have gone quiet. Here are the big ones

Montreala city where jackhammers and orange cones seem to be around every cornerwas unusually quiet on Wednesday after175,000 construction workers walked off the job.

An alliance of construction unionsfailed to reach any agreement with negotiators for construction companiesahead of Tuesday's midnightstrike deadline.

The Quebec government urged a swift resolution to the labour conflict and has threatened to introduce back-to-work legislation.

Lionel Perez, the Montreal executive committee member responsible for infrastructure, said roughly 60 city projects have ground to a halt.

Here are some of the big projects (and a few small ones) around Montreal affected by the strike.

NewChamplain Bridge

The newChamplain Bridge, replacing the most-used bridge in the country, is slated to be finished by late 2018.

The consortium building the new $4.3-billion structuresaid activity will resume when more than 600 employees on the bridge and nearby highway approaches return to work.

"It is too early to say what any potential impact might be (but) we are closely monitoring the situation,'' said spokespersonVronique Richard-Charrier.

Turcot Interchange

Many construction woes in Montreal can be attributed to the rebuildingof the Turcot Interchange.

According to the KPH-Turcot Consortium, approximately 300,000 vehiclesuse the interchange daily. At the end of April 2017, the consortium said the project was 40 per cent complete.

The new structure is supposed to be ready by the fall of 2020.
