The city has a new estimate on how much it could cost to widen Kenaston Boulevard.
A report to the infrastructure committee pegs the project at $450 million.
According to the report, a 2009 estimate of $129 million did not factor in the need to keep the St. James Bridge open in stages during construction.
There is also construction inflation and scope changes since the original number.
The city can't proceed with the widening until a deal is reached between a group of First Nations and Ottawa over the vacant Kapyong Barracks.
CTV News has been told an offer to purchase price is on the table, but there is no resolution at this point.
