I remember when they did something called "Hyper-Fix" to I-70, I think when they were building the new airport. There were incentives to completing the job early, and penalties for any delays. Do it like that. Betcha you'd see things getting done a lot quicker. I think @Leadeye 's quote applies.Because that milling machine might come from southern Indiana to mill in northern Indiana. The paver might come from a hundred miles away to work in the area. Not every INDOT district has all the equipment to complete these tasks.
Another example: We need a ditch cleared along hwy 13. Full of cattails. There is only ONE machine for that in the state. They work it by area. Just not my area. Lol
And: who the hell ever said a .gov could EVER be efficient, even when they try?
It is only efficient when an outside contractor is doing the job and time is money.
