We survived it last year, barely, but now we’re in for several “months of Hell” as closures of northbound I-5 across the Ship Canal Bridge return.

You deserve a pat on the back if you survived the “month of Hell” between July and August last summer.

You might need therapy to survive what’s about to happen.

Four ‘months of hell’ inbound

Four “months of Hell” will start this weekend with a full closure of northbound I-5 from downtown Seattle to University District. The Washington Department of Transportation (WSDOT) needs the weekend to set up a work zone across the Ship Canal Bridge.

Come next Monday, the two left lanes of the northbound Ship Canal Bridge will be closed 24/7, and this is going to last for four months.

I spoke with Tom Pearce, a communications specialist for WSDOT, about the upcoming work last year.

“We will work for about four months, and then we will pause and pick everything up when the World Cup comes to town,” Pearce said. “When the World Cup ends, we will have another weekend-long closure, reset the work zone, and then we’ll start to work on the right lanes of the northbound Ship Canal Bridge.”

And that will come with a second four-month chunk of lane closures.

I’m not sure if you remember just how bad these similar closures were for that one month last summer, but it was absolutely brutal.

To help with the traffic flow, WSDOT kept the I-5 express lanes open in the northbound direction the entire time. The rationale is that it is the direction of travel of the closures.

What that created was a daily one-hour delay, or more, for southbound I-5 drivers. Tens of thousands of southbound drivers use those express lanes every morning, and with that option gone, they had to stay in the main line, creating a daily five-mile backup to the Edmonds exit down to Northgate.

“We know that it was difficult for travelers, particularly for southbound in the morning on I-5,” Pearce said. “People did well at adapting and using other transportation methods and adjusting their schedules. It went relatively well.”

WSDOT is using all the data it collected during that month of closures and is using to help with congestion this time around.

Here’s the setup going forward

Northbound I-5 will be closed through the downtown corridor all weekend. When it reopens on Monday, only the right two lanes will be open until June 5. That weekend, the entire northbound freeway will be closed to remove the work zone.

The work will take a break during the World Cup until July 10. Then, northbound I-5 will be reduced to just two left lanes until the end of the year. The end date hasn’t been released. It was originally scheduled to wrap up in November.

This is going to cause significant delays around Seattle. My best advice is to alter your schedule and get on the road at least an hour earlier than normal.

And if you think you’ll just jump on the light rail out of Lynnwood to avoid the backup, you’re going to need a plan. That parking lot is full by 7 a.m. most mornings. It will likely be filled earlier than that going forward.
