They are doing construction on I-5 for the next two weeks, shoring up the bridges and viaducts and elevated parts south of downtown (image of bridge collapse in Minneapolis here). There will be only two lanes open (out of 4-5 usually in use). Commuting is going to be a f***ing nightmare. Thank god I don't have to get on I-5 to go to work, but I may get spill-over. One of the detours uses the West Seattle viaduct to Fourth Ave S. We'll see.
Reminder: Never reach for a falling knife.
