Talk:Rodovia dos Imigrantes

World's longest fully reversible highway?
Can anyone confirm this claim? 82.32.60.14 11:54, 6 July 2006 (UTC)

why do the carriageways cross over?
Seems a strange thing to do. --Jaded-view 16:06, 31 August 2007 (UTC)


 * It's because the second carriageway was built two decades after the first one. Initially the single-carriageway highway was just there to relieve traffic on the Anchieta highway. Then they decided to add a second one. I assume that by the time the second carriageway was built, tunnel construction technology had improved, allowing a different route for tunnels, which in turn resulted in the second carriageway coming out of the mountain at a different angle than the first. Or perhaps the steepness of the mountains didn't allow to build such wide roads side-by-side.  Cambrasa  02:38, 14 April 2008 (UTC)
