TORONTO — Ontario is taking a concrete step toward an idea Premier Doug Ford has championed to build a tunnel under Highway 401.

Ford has spoken often of the need to address gridlock and railed against lost productivity as a result of it.

He first raised the idea last fall of building a tunnel under Highway 401, and in response to concerns about a project of that size potentially costing tens of billions of dollars he has said the province would do a feasibility study.

However, he has pledged to get the tunnel built regardless.

The province has now issued a request for proposals for a study to determine the feasibility of a tunnel and several other options including an elevated highway, adding more lanes and truck-only lanes.

The request says the study should assess the larger options — including the tunnel — on a long-term horizon, specifying the year 2051.
