Where the biggest delays have been so far, post-viaduct closure

VIDEO: Post viaduct closure, where the biggest delays have been so far

Since the closure of the Alaskan Way Viaduct Friday, Kirkland traffic data firm Inrix found the locations where the biggest delays are happening.

The data looks similar to that from the last time the viaduct closed in 2016.

The largest delays have been south of Seattle on I-5, the West Seattle Bridge and traveling through SoDo on First Avenue South.

Congestion has started early – between 5:30 and 6 a.m. -- and begins to ramp up again around 2 p.m.

It’s extended later as well – usually ending around 10 a.m. in the morning and 7 p.m. in the evening.

Since the viaduct closed, there’s been relatively few crashes, and timely responses to clear those incidents have prevented severe backups.

But if drivers go back to old habits of driving alone, there will likely be a dramatic increase in travel times, transportation officials say.
