WATCH: WSDOT concedes stray current risks on I-90 from cross-lake light rail

(The Center Square) – The latest status report from Sound Transit raises some major concerns about whether passenger rail service will be ready to safely operate across the I-90 floating bridge by May 2026 as scheduled.

In a December 5th status report to the U.S. DOT, Sound Transit noted “cathodic protection system may not be given acceptance by WSDOT prior to revenue service.”

In other words, the issue could impact the integrity of the I-90 floating bridge.
