The roads in the Metro-Nashville area are drying out after a snow event caused major traffic problems overnight Monday and closed schools Tuesday. Before the morning commute on Wednesday, officials with Metro-Nashville Public Schools (MNPS) are working to make sure the roads are safe for travel. They are making the rounds in the Metro area, checking spots that have been known to cause problems for travel. On any given morning, about 550 school busses carry around 45,000 students to school in Davidson County. The "Snow Patrol" looks for road conditions that could be hazardous for bus travel. Roadways that have been covered by shade for much of the day are among the areas of concern. As the temperatures drop overnight, patches of moisture can freeze and make travel dangerous. With News 2 cameras following along Tuesday night, MNPS Chief Operating Officer Fred Carr couldn't find any real threats to bus travel. Carr is one of the officials that makes the call on whether or not to close schools. "All of this looks really good," Carr said. "I don't see a show-stopper." Davidson County schools are expected to reopen on Wednesday.
