I wouldn't say failing and in dire need of repair. Over the past... 5 or 6 years WSDOT has done a pretty decent job prioritizing projects and getting things taken care of. There certainly are bad spots, but, overall I think they are doing a pretty fair job. Seattle faces interesting problems with the population booming here, so I can't fault them too much for falling behind.I bet your road infrastructure is still failing and in dire need of repair or replacement, isn't it?
You Americans still have relatively cheap gas prices. Here in Ontario, the cheapest place is Costco, and they still charge C$1.10/L.
C$1.10/L roughly equals to around US$3.24/gal
I checked WA's cheapest gas prices for regular, and it's around US$2.69/gal
And yes, while we are still having issues with replacing outdated infrastructure. Most of it is not falling apart at the seams, yet, however I doubt they will be replaced in a timely manner either.
