PORTLAND – All lanes on the southbound span of the Interstate Bridge will close the night of Saturday, Aug. 24 for maintenance, one of several night closures on the bridge this month.

In addition, the middle and right lanes on the northbound span of Interstate 5 will close on three nights starting Friday, Aug. 16.

Here is the closure schedule.

The sidewalk on the northbound span will also be closed during these times. The northbound left lane will remain open. The Jantzen Beach on-ramp to northbound I-5 will be closed during the same hours. Crews will repair and replace overhead signs, replace lights and make pavement repairs.
