Finishing what what we started. A little more than a year ago, this section of the North Spokane Corridor that extends from Alki to Sprague didn't exist. In one week, we will set the final girders for this project. We've even poured quite a bit of concrete on the bridge deck.

Today's the day! Jump on Trains 503, 508, 516 and 519 to enjoy the new Amtrak Cascades trains. Super comfy seats. Tray tables in Triplicate - not even kidding! Adjustable cupholders. There is nothing like that new train smell.💚🤎🤍

Here's a look at where traffic is being diverted off I-5 in Tumwater. The interstate is closed in both directions. There are power outages and delays on detour routes in the area. Continue to delay travel if possible. We'll reopen the road as soon as we can.
I-5 is closed in both directions between Maytown and Tumwater. There is no ETA for reopening. If possible, delay travel until the road reopens. Power outages and delays on detour routes are causing big backups. Real time travel info at wsdot.com/Travel/Real-time/M…

We're working with utility crews to cleanup downed wires on I-5 between Tumwater and Maytown. The road is closed. Traffic is diverted around the closure on SR 121. Avoid the area. If you're traveling, expect delays along the detour until work is complete.

UPDATE 3: Three left lanes of SB I-5 on the Ship Canal Bridge remain blocked due to a collision involving a semi. The left lane is closed just south of this incident for construction. We are seeing 6+ miles of backup into Shoreline. Consider taking SR 99 or other routes.
UPDATE 2: SB I-5 just north of NE 45th St on the Ship Canal Bridge is down to one lane due to a collision involving two semis. South of this, the left lane is closed for repairs. Access to EB 520 is not impacted. We are seeing about 5 miles of backup into Northgate. Plan ahead.

As noted, the schedule of test runs can change. Today's did. The test ended at Vancouver, WA, and is making the return trip from there. Because the schedule is off, there are no times to share for the northbound run. Catch it in the wild if you can.
Thursdays offer more chances to see the new Amtrak Cascades train. Departs Seattle 6:20 am-Arrives in Portland 9:42 am. Departs Portland 10:50 am and reaches Seattle near 3 pm. These are training runs so the test schedule is subject to change. Photo courtesy of Nathan Bofto.
