The province is launching a two-year study that will look at upgrades to the Thunder Bay Expressway.

The study will examine the feasibility of widening the Expressway to a four-lane divided roadway for 13 kilometres, between Arthur and Balsam Streets, as well as the possibility of building interchanges at six locations.

The MPP for Thunder Bay Superior North said the study will consider everything, including how the project could affect nearby homes.

"You need to look if indeed you were to recommend dividing the highway what does that mean for property," Michael Gravelle said. "[It’s] the same thing for interchanges."

Gravelle said the goal is to improve safety and traffic flow on the Expressway.

The study will begin this summer and is expected to be completed by 2015.
