eastern Vancouver to Salmon Creek. By October, the new Oregon alignment had gained the approval of all local governments along its route except for Washington County, which proposed a western bypass that was rejected by the state government. The Oregon State Highway Commission adopted the West Linn–96th alignment on November 19, 1965, and forwarded the proposal to the BPR for approval despite opposition from Washington County and residents at public hearings. The Washington side's routing was finalized in late December and was also forwarded to the BPR. The BPR approved the revised routing in Oregon in March 1966; this was followed two months later by approval of Washington's alignment. I-205 was also integrated into the state highway system of Oregon as East Portland Freeway Highway No. 64 on April 21, 1966. The 52nd Avenue alignment was revived as a separate freeway proposal in a long-term plan but was never fully funded. In 1969, the federal government approved the Mount Hood Freeway as part of the relocation of I-80N (now I-84) from the existing Banfield Expressway; the new alignment would have been partially concurrent with I-205. The move was reversed in 1974 when the Mount Hood Freeway was canceled entirely in 1974. Tualatin–Clackamas construction Preliminary work on the West Linn–Oregon City bridge, now named the George Abernethy Bridge, began in April 1967 with piledriving to determine the bridge's foundation requirements. Construction of the bridge would have required the closure of access to a popular fishing site on the Willamette River, causing local sport fishers to protest; a nearby site was later donated for use as a new boat launch and public fishing area. Demolition for the bridge project, which included the destruction of an existing shopping center, began in January 1968, and construction of the bridge itself was underway a month later. The George Abernethy Bridge opened to traffic on May 28, 1970, and cost $17.1 million to construct (equivalent to $ in dollars), completing the first section of I-205. Construction on the second section of I-205, which spanned between I-5 in Tualatin and the bridge's approach in West Linn, began in 1968 and was completed on January 12, 1971. It cost $22.5 million (equivalent to $ in dollars) and required the removal of of soil and rock. Work included the blasting of basalt cliffs for over a year during daytime hours. Excavation for the project caused a series of landslides
