Multiple small brush fires were burning in Elysian Park Friday, shrouding the Arroyo Seco Parkway in smoke, firefighters said.

The first blaze was reported at about 4:30 p.m. on Radio Hill, and the other shortly before 5 p.m. in the area of the northbound 110 Freeway and Stadium Way, according to alerts from the Los Angeles Fire Department.

Each was initially estimated to cover less than an acre, and there were no immediate threats to residences or evacuations ordered.

The Stadium Way fire had only burned an acre when it was extinguished around 5:30 p.m., firefighters said.

The fire on Radio Hill, being dubbed the Broadway Fire, could potentially threaten critical communications infrastructure, LAFD said.

Aerial video from Sky5 showed crews were working to attack multiple spot fires in the area both in the air and on the ground.

Freeway traffic was expected to continue to be affected as LAFD mopped up the flames. Motorists seeking to use the Arroyo Seco Parkway through Elysian Park were advised to take an alternate route.

The cause of the fires was under investigation.

No further details were available.
