Actually, there has been a huge push in many places to update the major bridges, especially freeway bridges.
But that may ignore the rural roads. Maybe our politicians have forgotten that not all driving is done on freeways.
Thinking of bridges. There are two I-5 mirror image bridges crossing the Columbia river.
https://en.wikipedia.org/wiki/Interstate_Bridge
Bridge 1: 1915-1917, $1.75 Million ($32 Million Inflation adjusted).
Bridge 2: 1958, $14.5 Million ($118.9 Million Inflation adjusted), an almost identical bridge was built across the river along side of the original.
Bridge 3: Planned replacement for both spans. Cancelled in 2013. $3.4 Billion to $10 Billion estimated cost for the replacement bridge. Cost overruns?
So... almost a 10,000 fold increase in cost. For that kind of money, I would think they should be able to build a thousand lane bridge a whole mile wide.
