SR 99 reopens to traffic on time Wednesday

We made it, Seattle commuters. It wasn’t easy, but the longest closure of SR 99 in nearly three years has come to an end.

Both directions of the highway reopened to traffic at 4 a.m. Wednesday, Aug. 27.

Thanks for doing your part to reduce congestion. Traffic was worse than usual, but we expected that. And had you not heeded our suggestions, things would have been much, much worse.

Visible progress

Of course when you’re sitting in traffic, it’s easy to forget that the headaches we’re enduring have tangible benefits. In the case of the four-day SR 99 closure, we came away with plenty to show for our shared sacrifice.

Most notably, crews building the future north portal of the SR 99 tunnel demolished and replaced the section of SR 99 that crosses above Broad Street in Seattle. It looks easy in this time-lapse video, but completing this work and reopening the highway in four days was no small feat. 

Additionally, during the weekend portion of the closure, crews took advantage of the empty highway by completing necessary work elsewhere along the corridor. They replaced 81 concrete panels on SR 99 south of downtown, repaired an expansion joint at the Seneca Street off-ramp from northbound SR 99 and cleared ivy from the Alaskan Way Viaduct to make future maintenance of the structure easier.
