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.

Bars are stacked by today's condition rating. 8,516 bridges are counted. Build years before 1900 are counted only when credible. 41 of the 49 bridges in the 1900s bar are recorded as built in exactly 1900, which is likely an estimate rather than a date.
