About State 57

State 57 once followed Brea Blvd and Brea Canyon Blvd to Mission Blvd in Pomona. In 1998, Route 57 was extended north from I-10 to the present SR-210/I-210 junction. Signage was changed in 2002 when the Foothill Freeway was extended. Plans in the 1990’s called for a tolled extension south from I-5 to I-405 via a viaduct over the Santa Ana River.
