Maintenance work on both spans of the Interstate 5 Bridge will cause intermittent delays and multiple bridge lifts during three nights this month, according to the Oregon Department of Transportation.
Crews will be lubricating steel bridge cables by hand -- a process they've carried out since the original span opened in 1917. The work requires bridge lifts and delays of up to 20 minutes at a time, according to ODOT.
The lifts will begin at 10 p.m. Wednesday, June 12, and Thursday, June 13, continuing until 5:30 a.m. the following mornings. Maintenance lifts will also occur starting at 9 p.m. Saturday, June 22, until 9 a.m. the next day.
