Length Length, for now from the 1989 U.S. Numbered Highways . When the distance is significantly less than the maximum, it is in Italics. Replaced by Current route numbers of sections decommissioned. Probably should be moved to the other table. Note Other notes, and for now, things I still need to check on maps.
Italic font indicates a decommisioned route, or a city or state no longer part of an existing route.
It is also used for split and alternate routes no longer numbered. Bold italic font indicates an original 1926 route or city no longer commissioned. Parenthesis in the Via section are used for current numbers of decommissioned split or alternate routes. The wider your browser window is, the more readable it will be. I'm trying to get the width down without removing too much information.
