Cedar Rapids Gazette: From railways and roads to drinking water and energy, the systems Iowans depend on are only mediocre and need attention, according a report released Thursday. The American Society of Civil Engineers released its authoritative 2019 Report Card for Iowa’s Infrastructure, which grades the state in a dozen categories. The last report was in 2015. Efforts to repair the state’s aging infrastructure have proved somewhat successful, as the group increased Iowa’s overall grade from a C- in 2015 to a C this year.
