The City of Wilsonville and Oregon Department of Transportation (ODOT) are partnering to improve traffic flow and reduce congestion on the I-5 Boone Bridge heading south from Wilsonville. The “Southbound I-5 Boone Bridge Auxiliary Lane Study” plans to examine the traffic impacts and costs for adding an additional lane on I-5 from the Wilsonville Road interchange (Exit 283) south past Miley Road (Charbonneau Exit 282B) to the Aurora/Canby/Hubbard Highway 551 interchange (Exit 282A).For more information on the project and to sign-up for updates, see www.ci.wilsonville.or.us/I-5BooneBridge.The study is one component of several projects that the City is undertaking to reduce morning and evening commute-hours traffic congestion in the I-5/Wilsonville Road interchange area. Additionally, the planning effort is part of the larger City Council-directed push for a more comprehensive “South Metro I-5 Corridor Study” that would examine the costs and benefits of a range of potential highway improvements to I-5 from Tigard/Highway 217 to Aurora/Donald Ehlen Road Exit 278, along with increased public-transit options.After the Council approved a $50,000 City contribution to the study, the planning process started in October 2017 and concludes in the summer of 2018. The three phases of study work include:
During legislative hearings on the successful “Transportation Investment Package” (House Bill 2017) passed in 2017, a Congestion & Freight Mobility Workgroup estimated that the “Boone Bridge & Lanes” project would cost $120 million and could be constructed in 10-15 years. The City and ODOT seek to accelerate potential consideration of the project by obtaining a more accurate cost estimate and traffic-mitigation impact of potential improvements.
