Tunnel safety

Tunnel safety

The SR 99 tunnel is one of the safest tunnels ever constructed, built to withstand strong earthquakes and equipped with smart safety systems designed to keep traffic moving and people safe. In the rare event an emergency requires drivers and passengers to leave the roadway, there are doors every 650 feet leading to safe areas to wait or exit the tunnel. An exit pathway runs the entire length of the tunnel and is equipped with its own state-of-the-art ventilation and fire suppression systems. Tunnel operators will monitor the SR 99 tunnel 24 hours a day, 7 days a week, utilizing an extensive camera system able to detect anything unusual inside the SR 99 tunnel.
