Nah, it does seem like it's worse. Who knows why? One thing I did think of is the population growth. The populations of Bell, Brazos, Montogomery, and Harris Counties combined have probably tripled or maybe quadrupled over the past 40 years. I know a lot of the 485 traffic has historically been local Milam County folks, but I would think there has been a big increase in 485 traffic whose origination or destination is one of those above mentioned counties. Heck, most people I know that travel between Bell and those counties use 485.
Also, I assume there is increased traffic, especially trucking, on 77. Gotta think population growth and perhaps NAFTA have resulted in simply more vehicles heading north and south.
In short, I wonder if NON-intra-Milam County traffic has increased dramatically in recent decades, simply resulting in more opportunities for collisions. I don't know. Just a hunch.
Granoleater is probably right. I don't know what TxDOT's criteria is for designating an intersection for an overpass, but one right there would help. Maybe the volume of traffic on 485 isn't deemed high enough. Maybe it's too costly. Maybe no one cares. Does seem like, given the injuries and loss of life that it's worth a look.
