Interstate 440 (abbreviated I-440, signed as Four-Forty Pky) in Tennessee is a 7.64-mile (12.30 km)-long loop connecting Interstate 24, Interstate 40, and Interstate 65, bypassing downtown Nashville to the south. The section between I-24 and I-65 was completed in 1986, and the section between I-65 and I-40 was completed in 1987. It was the most expensive road, per mile, built in Tennessee at the time. In the beginning it was called Four-Forty Parkway and trucks were not permitted to use it, but eventually it became open to trucks. With only two lanes in each direction and an AADT of 106,219, it is one of the most congested rush-hour highways in the state.
