A new underground tunnel in downtown Ottawa for electric trams could be part of a plan to expand transit service to bring commuters from the rapidly growing communities in west Gatineau across the Ottawa River.

There is not yet an estimated cost of the project.
The STO says Gatineau and Ottawa residents will have an opportunity to weigh in next month during public consultations.
