{}Parts of I-459 in Hoover will be shutdown overnight this week for repairs. A portion of the work will include guardrail upgrades.Starting Sunday at 7 p.m., the inside lanes of I-459N from Highway 150 to U.S. 31 will be closed for repaving. The inside lane of I-459S in the same area will be shutdown for guardrail upgrades and shoulder grading. The lanes will reopen at 6 a.m.. The work will be done overnight through Wednesday.The same schedule will be followed Wednesday through Friday to make changes to guardrails on I-459N and to repave I-459S. Again, the same stretch of interstate will be affected. The guardrails will consist of wire barriers. They are designed to keep vehicles from crossing the median into oncoming traffic.Earlier this month, three fatal accidents on I-459 claimed the lives of four people. Hoover Mayor Gary Ivey hopes the guardrail changes will make the interstate safer and save lives.
