Look at Wilcox County. Half brown, half green There's very few roads in Wilcox County big enough that a deer cant jump over. Rut map shows green on both sides of the river so that's not the inhibitor. Brown drops down almost to the line over on the east side of county. Nothing there to stop movement. I could see a major 4 or 6 lane interstate with an 8 ft high fence along it, prohibiting deer movement, but generic paved roads throughout counties? There's just no way. Deer cross paved roads all the time.

HWY 80 between Demopolis and Selma is a wide 4 lane in 90% of the spots and deer cross back and forth across it all the time. Probably dont cross it as much as they would if it was a two track dirt road but if one wants to get to the other side, it doesnt slow them down at all. We see bucks and does crossing it all the time, especially during the rut.
