CABOT, Ark. — Construction is now underway in Cabot over Interstate 57 and is expected to last between two and two and a half years. If you’ve ever sat in traffic trying to get on or off Interstate 57 at Highway 5, you’re not alone. With Cabot growing fast, ARDOT says this interchange can’t keep up. Now, the agency is beginning a 53.9-million-dollar project - redesigning one of the busiest interchanges in Central Arkansas.
