The federal government has confirmed a financial commitment to expand a three kilometre stretch of the 417.
Ottawa South MP David McGuinty announced up to $47.57-million in funding today, matching a figure from the province.
MPP Bob Chiarelli, who previously revealed the expansion was coming, was also on hand to make the commitment.
The plan is to expand the Queensway between Maitland and Island Park from six lanes to eight.
The project also includes rehabilitating the Merivale Road bridge.
