Interstate 345

Interstate 345 (I-345) is the 1.4-mile-long (2.3 km) freeway connecting I-45 (which ends at the intersection with Interstate 30) with U.S. Highway 75 (US 75, North Central Expressway) at Spur 366 (Woodall Rodgers Freeway) in Dallas. Few maps actually display the road as I-345; sign posts on the road only show US 75. In recent years, a debate over whether to maintain or decommission I-345 has received increased attention from several Dallas media outlets.

Route description

I-345 serves as the connection between I-45 and the North Central Expressway (US 75). It starts at the intersection of I-45 and I-30, passes by downtown Dallas and connects to US 75 at the Spur 366 junction. The entire stretch of I-345 is elevated allowing for better connections between the Central Business District and Deep Ellum.

Although I-345 uses its own mileposts, the exit numbering is not consistent. The exit numbers on the northbound stretch count upwards from the I-45 numbers (the exit for Spur 366 being labeled as exit 286A), while on the southbound stretch the Spur 366 exit is numbered exit 1A, followed by the exit for Ross Avenue numbered exit 285.
