of the Columbia and Willamette Rivers. Portland area In northwest Portland, US 30 is sandwiched between Forest Park to the west and the Willamette River to the east. South of the Linnton area, US 30 Bypass (Northeast Portland Highway No. 123) heads east across the St. Johns Bridge. US 30 continues south along St. Helens Road, then later on Yeon Avenue through an industrial area as it approaches Downtown Portland. On the edge of Downtown Portland, US 30 briefly becomes a freeway, utilizing part of the route of the cancelled I-505, until its interchange with I-405 at the western end of the Fremont Bridge. US 30 crosses the Fremont Bridge (along with I-405), on the Stadium Freeway No. 61; at the eastern end of the bridge it joins Interstate 5 south for approximately one mile on the Pacific Highway No. 1 and then joins the Banfield Expressway (I-84), where it becomes the Columbia River Highway No. 2. For the remainder of its route in the Portland area, US 30 shares an alignment with I-84. I-84 passes through the eastern Portland suburbs of Fairview, Wood Village, Gresham, and Troutdale in this fashion. US 30 Bypass rejoins US 30 in Wood Village. U.S. Route 30 Business was a spur from US 30 Byp. northeast of Downtown Portland, across I-84/US 30 to Oregon Route 99E east of Downtown, just east of the Burnside Bridge. It has not rejoined US 30 on its west end since US 30 was moved onto I-405 and I-5 around Downtown.
