Make a U-TURN and go back to U.S. 41
U.S. 141 is a 2-lane highway as soon as it exits off of U.S. 41. But it is going to converted to 4 lanes sometime, due mostly to the high traffic volume during the summer vacation season. But this will probably not be in the near future, unfortunately. So for now, travelers will have to go through town after endless town.
