Over 10 million dollars per mile?
“•Construct a new 2-lane undivided road – about $2 million to $3 million per mile in rural areas, about $3 million to $5 million in urban areas.
•Construct a new 4-lane highway — $4 million to $6 million per mile in rural and suburban areas, $8 million to $10 million per mile in urban areas.
•Construct a new 6-lane Interstate highway – about $7 million per mile in rural areas, $11 million or more per mile in urban areas.”
Over $18M per mile considering this plan is for only 1250 miles.
Over $3K per linear foot seems excessive. Solid concrete at $100 /cy could run 2’ thick for 20’ below ground and 50’ above ground and still only cost $500 per linear foot.
