In winter, about once an hour maybe. In summer, every 15 minutes or so as my road serves as one of the detours for the construction. Generally quiet except for the fact it's a very rough road and people think school zones are drag race strips so people come through at 70 or higher and when they bottom out the car on the bumps it's very loud. Then there's this one guy at least once a day that passes with an empty trailer and that thing just bounces around like crazy smashing back to the ground only to bounce up again. Other than that though it's pretty quiet, can't complain.
