This means that any large business in town moves to the bypass, or any new business or shopping center gets built right on the bypass and requires a traffic light for the street intersecting where it's built, or if it's a Wal-Mart, they get their own traffic light. Before long, the old road through town has a bunch of old run-down shopping centers and the bypass is no longer a bypass, but a congested, frustrating 4-lane road with tons of stops.

As far as your statement is concerned, when Mdot builds a bypass in northern MS, the population density is nowhere near what we have around here, so naturally, they can limit the driveway connections. We don't have that luxury here. I work for ALDOT in Moulton, and I don't have the answers. ALDOT does stupid stuff, granted.
US. 72 between Athens and Huntsville needs widening in the worst way, but due to all of the homes and businesses alongside it, the work would be prohibitively expensive. The highway was built in different years that resulted in different roadway grades between the eastbound and westbound lanes. To correct this, and it will have to be one of the first things to be fixed, will require building up the lower sections, or cutting down the higher sections so that the grades match from one side to the other, as well as allow for any super-elevation that would need to be incorporated into the curves. Only then could the median be properly constructed and filled in and the shoulders cut out, rebuilt for the increased loads on them, and incorporated into the normal travel lanes. Plus, new shoulders would have to be added for safety.
All intersections and driveway entrances would have to be rebuilt, or eliminated to smooth traffic flow. How long do you think this will take, much less cost? My guess is between 5 and 10 million dollars per mile where the worst congestion is and somewhat less in the rural areas, but I could be off by several million dollars per mile, and not on the less expensive side. This is just for the construction phase. It does not even factor in right of way purchases which will add several more million dollars to the cost. Also, as ALDOT fast-tracks this (yeah, right), traffic will increase, the costs will go up, and we will cry a whole lot more because of the carnage and the delays that take place before, and during construction. Just because you have a set of plans does not guarantee that the work will go smoothly. There are problems in the design that need to be addressed, work issues will come up that need attention, weather will slow work, and whatever else could happen probably will. Funding may be late, or could be pulled altogether for a period of time. These are some of the issues, and I am sure there are many more that will come up when the work is scheduled, and in progress.
