WSDOT is considering moving the 520 HOV lanes from the right-hand side to the left, where HOV lanes typically run. They might even do this before the new bridge is in.
The main impediment to moving them thusfar, in my understanding, is the fact that the right-hand lanes are former shoulders not safe enough for general purpose traffic. But maybe they’re getting an upgrade, or WSDOT has decided that they’re safe enough.
