As much as I hate contruction, I do like good highways. And construction/reconstruction of aging highways is the only way we get them. We have been traveling I-35 between Dallas and Georgetown to our hunting area several times a year for the last 45 years. Never once has there been a year when there was no construction. BUT, the highway has, for the most part, been a very good highway thru those years.
I have on occasion tried a bypass to get around construction, but have generally found I would have been better off just to tough it out and go on thru the construction area. The construction company usually has an obligation (read bonus/penalty) to keep the traffic flowing. A check on here a day or so before you go thru will usually find someone who just went thru and can give an update on the drive.
