Interstate 605 runs through the northern city limits by the Pico Rivera Sports Arena. Also, two of Pico Rivera's roads are signed off as California State Highways, though Caltrans turned over maintenance of both highways within city limits to the city. The two highways that run in Pico Rivera are California State Route 19 (Rosemead Boulevard) and California State Route 72 (Whittier Boulevard), but only the portion from Interstate 605 to Rosemead Boulevard is signed off as State Route 72, while all of Rosemead Boulevard in Pico Rivera is signed off as State Route 19.
