JACKSON, Miss. – Some places in downtown Jackson are in for a few upgrades, which are disrupting the flow of traffic this week. The Pascagoula Street tunnel is being repainted. It is closed daily this week from 6 a.m. to 3:30 p.m.. Some touch-ups are also in the works on the “Welcome to Jackson” mural, thanks to funding through the John and Lucy Shackleford fund at the Community Foundation of Mississippi. They wanted the downtown area to be in top shape for the upcoming National Folk Festival.
