The 2012 map went live online today.
Assorted sources report that the number of maps printed was cut nearly in half this year. This is not necessarily a bad thing as long as there are still enough. GPSs and smart phones won’t give you the size or large-scale detail you can get with paper. Each device has its place.
I haven’t scanned for corrections in a while, so it seems about time to re-check mileages around new four-lane segments.
(Ironically, in the first link above, Radio Iowa reports the DOT says that drastically cutting the number of maps printed will increase per-map costs.)
