Ottawa residents expressed mixed opinions at an open house to introduce residents to the city's plans for a downtown tunnel on Monday night.
The cost of the first phase of the new light rail transit project has soared to $2.1 billion, up from an earlier estimate of $1.4 billion.
The plan includes light rail lines from Blair Road to Tunney's Pasture, with a downtown tunnel designed to get rid of traffic congestion in the city's core.
"We're going the right direction. I'd like to see it progress a little faster," one resident told CTV Ottawa on Monday night.
"It seems a bit expensive. When you have the option of doing surface rail, it's a bit strange," said another.
Council will consider public feedback in mid-December.
