Several comments mention the upcoming intersection as if crossing traffic were likely. It is actually a classic cloverleaf. Search google maps for Renton Washington and look for highway 167, where the incident occurred, and its intersection with I-405. I haven't been over there for several months, so I'm not sure how up-to-date the satellite view is, but it looks right to me.

Grady Way is just a few hundred feet north of I-405, and it's a fairly busy (traditional) intersection.

Also, the concrete median the truck had bounced off of ends just before Grady Way. It's likely the guy would've either crossed traffic at Grady Way or moved into oncoming traffic. Either way, there's a high likelihood of serious injury or fatality stemming from an out-of-control vehicle moving through that intersection.
