Officials said work on the 605 South Street off-ramp added lanes, upgraded pedestrian facilities and lighting, and is part of a larger I-605/91 package aimed at improving traffic flow and business access in Cerritos and Artesia.

Unidentified Speaker 1, identifying themself as chairman of the Los Angeles County Metropolitan Transportation Authority (LA Metro), said he was "so excited about this project" after completion of improvements at the 605 South Street off-ramp that serve Cerritos and neighboring Artesia.
