for about , crossing the Willamette River on the Boones Ferry and continuing south for another until finally ending at Oregon Route 99E at Aurora, for a grand total of about or so. The southern terminus was scaled back to Wilsonville (current I-5 exit 286) with the completion of I-5 to Portland. This older highway, called the Beaverton-Aurora Highway, was kept in the state highway system as the Beaverton-Tualatin Highway No. 141, and was recently given the route designation OR 141. The intersection of OR 217 and US 26 in Beaverton was replaced with an interchange in 1986 after two years of construction. Future ODOT started construction on the Auxiliary Lanes Project in December 2021, which aims to add a southbound auxiliary lane from Exit 2A to Exit 6 and a northbound auxiliary lane from Exit 6 to Exit 4. The Allen Boulevard southbound on-ramp and Denney Road southbound off-ramp will be removed for a new frontage road being constructed in place of it.
