A sewer repair project will close the Interstate 5 ramps to Southwest Multnomah Boulevard for 45 days beginning Monday, Oct. 3.
The ramps should reopen by mid-November.
Portland's Bureau of Environmental Services said Multnomah Boulevard would remain open during construction. The exit from I-5 south to Southwest Multnomah Boulevard westbound (Exit 296B) and the entrance to I-5 north from eastbound Multnomah Boulevard will close. Signs will direct traffic to detours.
Contractor Emery and Sons is repairing the 50-year-old Burlingame trunk sewer line by inserting a liner in the sewer pipe to form a new interior surface. Emery and Sons needs to pump sewage around the repair area through surface pipes that will temporarily block the ramps connecting Multnomah Boulevard with I-5.
Some trees on the north side of Multnomah Boulevard between Southwest 22nd and 28th avenues will be removed to make room for the project. The trees are adjacent to Qwest, the former Sears Armory facility and an apartment complex. New trees will be planted once the sewer line work is completed.
