DescriptionVista Ridge Tunnels east end P2236a.jpeg
The east end of the Vista Ridge Tunnels carries Sunset Highway through Vista Ridge, a small portion of the Tualatin Mountains in Portland. The road slopes steeply downhill to downtown Portland. All six lanes separate—the outer four lanes join with I-405, the middle lanes connect to SW Market Street (eastbound) and SW Clay Street (westbound). There are less than 1000 ft (300 m) between the tunnels and the lane splits.
