The local Interstate is in the process of connecting feeder highways, widening, and upgrading to connect sections already completed in the city it travels through. It's overdue, but money takes time to be granted by TxDot, and the design takes years to complete after the funds are available. The construction will stretch until near 2030, and the normal complaining is in full force.
Added to this construction is the near future widening of an arterial highway. Right-of-way is almost completed, and the design looks like it's completed. The construction will involve about about 8 miles of widening, and the completed construction will take up the complete right-of-way. From past experience, the initial construction will involve turning one shoulder into a travel lane, and removing the other lane to construct the new concrete. Before that happens, part of the new drainage structures will be completed, and eventually this section will be opened to divert traffic. The other section will be completed, and the highway project will be done.
This all means years of detours, dealing with the most ignorant of drivers, constant complaining, and my efforts to avoid all by taking alternate routes. I'm lucky, I can avoid these sections of highway, and not have to deal with the new construction. My experience tells me the worst of drivers seem to be found in construction zones, and the havoc they cause is something I avoid like the plague. With the sometimes poorly maintained detours knocking out front end alignment, taking extra time by traveling other routes is worth the effort.
