We have the 4 year plan here which generally is most and turns into 5-6 years.
We currently have several segments of freeway on every direction under construction. All are having a lan in both directions added, toll lanes. All are scheduled to be finished in 4 years and all will be obsolete before they are complete.
I find it amazing that in 1954 they built a 5 mile suspension bridge over deep water and it was finished in 4 years without modern technology and equipment.
As a side note, I had a pot hole in the road in front of my house. I called several times and had no response,. I went to the store and bought a bag of cold patch and filled it myself. I received a ticket for interfering with the road commission. 50 bucks but the hole is filled.
