Interstate 124とは 意味・読み方・使い方

Interstate 124 (I-124) is an unsigned designation for a short segment of a four-lane limited access highway located in Chattanooga, Tennessee, USA. During periods where this two miles (3.22 km) long segment of U.S. Route 27 has been signed as I-124, it has served as a spur route of Interstate 24 to downtown Chattanooga. The road segment has not been signed as I-124 for several years (it is marked on overhead signs and mile markers as US 27), and the Tennessee DOT official map no longer designates it as I-124, but some DOT publications still make reference to the designation. The US 27 freeway diverges from I-24 just before the Moccasain Bend in the Tennessee River, continues North through downtown Chattanooga, and then across the Tennessee River as a limited-access freeway on the P.R. Olgiati Bridge. The river is the point at which the I-124 designation ended. After crossing the river, the freeway continues under the US 27 designation for another 30 miles (beyond which the spur continues under the TN 111 designation for a further 20 miles).
