Thanks greyfoxx. The section from Bernalillo to Tramway is one of the nastiest sections of I-25 and it is still two lane each direction. I suspect that they are delaying reconstruction so that people will give up their cars and take the train which parallels that section of interstate.
That section of I-25 used to be my daily commute. It was always a disaster when there was an accident, which seemed to happen pretty regularly (usually a rollover in the median). Some of them were probably caused by people turning around in the median because they missed the Bernalillo exit and didn't want to go to Tramway to turn around, so they risk a u-turn into 80 mph traffic. I always thought that was a real brainiac move.
Sometimes I would call home and have my wife check the road for me to see if it was backed up or not. Living in the Rivers Edge area, we could see that section of the freeway from the back of our house.
