U.S. Route 24
U.S. Route 24 (US 24) is one of the original United States highways of 1926. It originally ran from Pontiac, Michigan, in the east to Kansas City, Missouri, in the west. Today, the highway's eastern terminus is in Independence Township, Michigan, at an intersection with I-75 and its western terminus is near Minturn, Colorado at an intersection with I-70. The transition from north–south to east–west signage is in Toledo, Ohio.
Route description
Colorado
In Colorado, US 24 runs from Interstate 70 (and implicitly with, U.S. Route 6) from Minturn where it goes through Minturn and continues south to the Continental Divide at Tennessee Pass. It continues south to Johnson Village and then joins with U.S. Route 285 northbound to the Trout Creek Pass. After the pass, US 24 separates from US 285 and continues east to Colorado Springs and then northeast to Limon, where US 24 joins I-70 for most of the rest of its routing to the Kansas state line.
When the United States Highway System was started in 1926, US 24 in Colorado was designated U.S. Route 40S. It began in Grand Junction and went east along the current Interstate 70 corridor to Minturn, from which it follows the current route to Limon. From Limon east to the Kansas border, the current US 24 was designated U.S. Route 40N. US 40S west of Limon and US 40N east of Limon received the US 24 designation in 1936, when US 24 was extended west from Kansas City, Missouri. The segment between Grand Junction and Minturn was decommissioned in 1975.
