The closure is part of the two-year Clackamas Regional Center Mobility Improvements Project designed to improve safety and traffic flow for all travelers, including new sidewalks and bike lanes, restriped roadways, new traffic signals, I-205 bridge widening, stormwater facilities and ADA ramps. This project is funded through tax increment financing from the Clackamas Town Center Urban Renewal District. All work is expected to be completed by the end of 2021.
