The former west portal of the twin-tunnel Mount Baker Ridge Tunnel on Interstate 90, in Seattle. During modification work beginning in 1989, this portal was permanently removed and the tunnel was effectively extended westwards by the construction of a new concrete "lid" over a nearly 2,000-foot stretch of I-90's older lanes, the lanes pictured here. (A new, parallel set of freeway lanes, using a new tunnel, opened just north of this location in 1989.)

Until 1989, the lanes were reversible, and signals above each lane within the two portals show the direction of traffic at the time of the photo. This was an afternoon rush hour view, when three lanes were open for eastbound traffic (i.e., generally heading away from Seattle) and one lane for westbound traffic. A Metro Transit bus on route 220 is among the vehicles using the sole westbound lane in this view.
