Each bar runs from the year the bridge was built to today, colored by its overall condition (green good, orange fair, red poor). A white notch marks a recorded reconstruction; many of these bridges have been rebuilt or widened more than once, and the inventory keeps only the most recent date. Daily traffic is the latest count.
