The SR 16 Westbound Nalley Valley Interchange project improves the westbound connection between I-5 and SR 16. The project team constructed new westbound bridges over Nalley Valley and eliminated traffic weaves through a new direct connection from southbound I-5 to Sprague Avenue and westbound SR 16. Improvements also included building a new Sprague Avenue on-ramp to westbound SR 16, a new eastbound SR 16 off-ramp to Sprague Avenue, and a new flyover ramp from northbound I-5 to westbound SR 16 and Sprague Avenue.
