Robert Vessey says his department is working with a local contractor to open an asphalt plant in Prince County that was shut down for the winter.
Vessey says it's a necessary step as road crews work around the clock to repair the damage.
He says several kilometres of detour roads will be paved while long-term repairs take place on Route 2.
It could be six to eight weeks before the hardest-hit areas are repaired, including in Bloomfield, Tyne Valley, Huntley Bridge and along Route 131.
In some cases, Vessey says road workers are still waiting for water to recede before proceeding with repairs.
