The I-90 floating bridge carries no toll. WSDOT's list of Washington's tolled roads, bridges and tunnels names SR 520, the SR 99 tunnel, the Tacoma Narrows bridge, SR 509, SR 167 and the I-405 express toll lanes — and not this crossing.
Source: WSDOT · toll roads, bridges & tunnelsThe inside lanes are HOV lanes — carpools, vanpools, buses and motorcycles. WSDOT does not fix one statewide number for how many people that takes: the requirement is whatever the sign on the lane says while HOV rules are in force, so read the sign rather than a rule of thumb.
Source: WSDOT · HOV lanesWSDOT closes a floating bridge when the wind gets high enough, and the closure arrives as a WSDOT alert — which is the Alerts box on this page. WSDOT publishes no wind speed for this crossing, so this page quotes none; if the bridge is closing, the alert above is where it says so.
Source: WSDOT · statewide travel alertsSR 520 is the other cross-lake crossing. It is tolled in both directions at all hours, which I-90 is not.
