I 15 Thru Salt lake City?

We treat Salt Lake like any other big city we travel through, try to go through on a weekend, if it's a weekday we try to stay as close as we can the night before and travel through about 10:30 in the morning. Everyone is at work and it's before the lunch hour when they are out running errands. I 15 or 215 are about the same, we just stay on the main highway and go straight through. This has worked for us in the majority of big cities. Travel safe.
