A fire at a homeless camp spread to a dock near West Coast Event Productions on the waterfront early Friday morning, Portland Fire and Rescue said.
Crews responded to the fire in the 1400 block of Northwest Naito Parkway around 2 a.m.
Fire officials say no one was hurt, but there was one report of smoke inhalation.
Northwest Naito Parkway was closed for a short period of time, but reopened by 3 a.m.
Firefighters had some difficulty fighting the flames due to the location, but fireboats helped them.
