Traffic on the Queensway headed into the downtown core was a mess on Tuesday morning after a tractor trailer rolled over just before the Nicholas exit headed west.
Ottawa Fire's HAZMAT team was called in to clean up fuel that had leaked from the front of the truck.
The 61-year-old driver was conscious when paramedics arrived but he was rushed to the trauma centre with injuries to his face and chest.
He was listed in serious but stable condition.
The Ministry of Transport has been notified about the crash.
