Editing Orleans County, Vermont (section)

===Major routes===
The opening of [[Interstate 91]] north from Barton on November 9, 1972, and opening south from the county in 1978 affected the county in a similar way to the opening of the railway a century earlier. In 1980, the county registered its first population gain in a century.<ref name="autogenerated2" />

The interstate has its northernmost five exits in the county. Two of them are in the town of Barton, servicing the villages of Barton (exit 25) and Orleans (26). The other three are in the town of Derby: the southernmost of those (exit 27) actually leads to Newport city a mile away, while exit 28 services the village of Derby Center and the shopping areas along Derby Road. The last exit, 29, which is located less than ¼ mile from the Canada–US border, leads to the village of Derby Line and the town of Holland.

The county has {{convert|1041|mi|km}} of state highway and class 1, 2 and 3 roads. {{convert|606|mi|km}} of these are dirt roads (class 3). {{convert|141|mi|km}} are unmaintained roads (Class 4). As in most of New England, the county government does not build nor maintain any roads.

Derby has the most road mileage, 102; Westfield the least with 31.<ref>{{Cite web |url=http://www.aot.state.vt.us/planning/documents/highresearch/publications/2004hwymiles%5Ftown.pdf |title=Microsoft Word - 2004 Miles by County-Town.rtf<!-- Bot generated title --> |access-date=June 26, 2007 |archive-url=https://web.archive.org/web/20070705000033/http://www.aot.state.vt.us/planning/documents/highresearch/publications/2004hwymiles%5Ftown.pdf |archive-date=July 5, 2007 |url-status=dead }}</ref>
