I don't get what the tunnel is about. It's not big enough to carry a freeway, and right next to it is an underpass that might actually be big enough. Could the tunnel have been intended for a pair of train tracks?

As Arthur indicated in his post, the tunnel is intended to be used by an on-ramp (probably single lane) from the Seatac Airport Southern Access Freeway. However, at least as far as I know, that project remains unfunded.

It's worth mentioning the tunnel was built a number of years ago, back when 24th/28th was originally built and the overpass was put in (around 2017).
