​From major road repairs to building public toilets to giving a facelift to its arenas and baseball fields, the City of Montreal has released its list of capital spending priorities for the next three years.

The city is planning to spend $5.2 billion on capital works between now and 2018.

About three-quarters of that spending will go towards repairs and improvements to roads and other existing infrastructure.

The remaining 25 per cent will be spent on new projects.

Nearly $1.5 billion is earmarked for road works, including work on the Turcot interchange, redeveloping Plaza St-Hubert and improving a section of the north end of Papineau Avenue.

The city also plans to spend around $1.2 billion on its water infrastructure, replacing aging water and sewer mains, improving drinking-water production plants and building an ozone wastewater-disinfection project.

Special projects to celebrate Montreal's 375th anniversary are expected to cost $329 million. That includes the development of Parc Jean-Drapeau, the redevelopment of Sainte-Catherine Street West, the construction of an urban walkway from the mountain to the river and renovations to Viger Square.

Municipal arenas and baseball fields will get a facelift, at a combined cost of around $90 million.

The mayor also wants to implement the "Montreal, Smart and Digital City Strategy" at a cost of nearly $50 million.

That means investing in new transportation technology, building a "dynamic parking system" in underground lots and building a new website for the city.

Opposition doubts work will get done

The opposition at city hall is skeptical about whether the mayor's plans will actually become reality.

Projet Montréal Leader Luc Ferrandez said the city has managed to complete barely half of the projects announced in previous years.

"You can pour as much money as you want in this file, if it doesn't translate into real work, it's not important. And this is what's happening," said Ferrandez.

He said part of the problem is that the city has cut its workforce, leaving too few people to plan, let alone get the work done. Ferrandez said the city then turns to private contractors, but they often don't work to the schedule set out by the city.

But Coderre is confident the ambitious list of projects will see the light of day.

"We are not just putting a list to put a list," said Coderre. "That's where I am very vigilant, and the administration is very vigilant."
