It is interesting to note that the satellite image shows that the Red River it goes over is actually red.
The shot above catches the southern end of the RK/L&N/MC&L approach trestle. I was surprised that it is a non-trivial wood trestle. Later I found another RK bridge with a long approach trestle that was also made of wood. The shot below sacrifices catching the southern end of the trestle so that I can catch the part that goes over the river.
