Interstate 345 (I-345) is an unsigned 1.4-mile-long (2.3 km) Auxiliary Interstate Highway in the city of Dallas within the US state of Texas. It is a freeway that connects I-45 (which ends at the interchange with I-30) with U.S. Highway 75 (US 75; North Central Expressway) at State Highway Spur 366 (Spur 366; Woodall Rodgers Freeway). Few maps actually display the road as I-345; signposts on the road show US 75 northbound, while southbound the highway is signed as I-45. In recent years, a debate over whether to maintain or decommission I-345 has received increased attention from several Dallas media outlets. TxDOT elected to maintain the freeway by lowering it below ground and removing frontage roads.
