In one of my business trips to Hawaii, I noticed that they have figured out on the island of Oahu how to get necessary work done with the minimum of inconvenience on one of their freeways.

They start after rush hour and work all night until morning rush hour.  They grind up and remove a mile of asphalt in one lane and then replace it with brand new asphalt about 10 minutes behind the removal people.  By morning, voila! brand new replace road with minimum inconvenience to the public.  Eugene doesn't care enough about either its drivers, taxpayers or local businesses to even attempt such a thing.  The State Hwy Department did recently on Hwy 126, but that is in Springfield, after all.
