TLACS commissioning in Seattle, USA

Our team is reaching the first milestone in the commissioning of the TLACS (Tunnel Lighting Addressable Control System) this week, in the tunnel located on SR520 highway, in the Montlake district of Seattle, USA.

This tunnel represents a crucial component of a comprehensive project aimed at enhancing the mobility of people and goods around Lake Washington, within the SR 520 corridor that connects the city of Seattle to Redmond. The goal is to ensure safe, reliable, and cost-effective mobility while minimizing impacts on local residents.

Equipped with 456 luminaires, the lighting in this urban tunnel will be under the control of TLACS, supervised by TLACS-SCADA. The latter provides overall real-time and remote control and supervision. The commissioning is expected to be completed by spring 2024.
