U.S. 138 follows the South Platte River between U.S. 6 and SH 14 in Sterling and U.S. 30 in Big Springs, Nebraska. The route in Colorado serves the farming towns of Iliff, Proctor, Crook, Sedgwick, Ovid and Julesburg along the way. 59.82 miles of U.S. 138 travels through the Centennial State, the remaining 11.4 miles are located in Nebraska.

Since it was orphaned in 1931 (when U.S. 6 was extended over most of the original route of Former U.S. 38), U.S. 138 has the distinction of being one of the few three-digit U.S. routes whose parent was decommissioned but the child route remains. Other such routes include U.S. 199 (California/ Oregon), U.S. 166 (Kansas/ Missouri), and U.S. 266 (Oklahoma). Neither U.S. 99 nor U.S. 66 remain in service today.

The CDOT, CO 14 Sterling S-Curve project reconfigures the west end of U.S. 138 in the city of Sterling. The current one-way couplet will be eliminated, with both U.S. 138 and U.S. 6 south of Chestnut Street, shifting solely onto 3rd Street. This work coincides with the realignment of SH 14 over a former railroad right of way to feed directly into U.S. 6 and 138 at 3rd and Chestnut Streets. Sterling is home to 13,916 people and is the seat of Logan County. Nearby North Sterling Reservoir State Park and the Pawnee National Grassland offer recreational opportunities. Otherwise, Sterling is a regional city that offers amenities to the residents of several towns and rural areas within a multi-county radius. The elevation is 3,939 feet, with an average annual precipitation of about 13.42 inches.

One mile into Colorado, U.S. 138 approaches a diamond interchange with U.S. 385, a primary north-south route through Eastern Colorado. Photo taken 09/05/05.
U.S. 385 is one of the few major routes in Colorado that does not have any significant mountainous section. Established in 1959 from Big Bend National Park in Texas to Lead, South Dakota, U.S. 385 overtook a series of former state highways in eastern Colorado. Photo taken 09/05/05.
Prior to 1988, U.S. 385 followed Cedar Street northwest to cross the adjacent Union Pacific Railroad lines at-grade, intersecting U.S. 138 at Downtown Julesburg.1 Photo taken 09/05/05.
U.S. 138 west & 385 north
A farming community, the skyline at Julesburg is dominated by the large co-op grain elevator. The town was established during the frontier days as a trading post. Julesburg was named for the French trader Jules Beni who founded the town in 1859. Photo taken 09/05/05.
Julesburg is one of the lower communities in the state, with an elevation of 3,477 feet above sea level. Its location near the junction of Interstates 76 and 80 helped it to gain prominence as a service center for commercial traffic en route to Denver and the West Coast to and from the Midwest. Photo taken 04/22/17.
Downtown Julesburg occupies a four block area centered around 1st and Cedar Streets. Julesburg population numbers in the U.S. Census varied from 1,295 in 1990, to 1,467 in 2000 and back to 1,225 in 2010. Photo taken 04/22/17.
Trailblazers for U.S. 138 west & 385 north appear after their former merge point at Cedar Street. The mileage sign references Chappell, a town in Nebraska found along U.S. 30 and U.S. 385 near Interstate 80. Photo taken 04/22/17.
U.S. 138 west
U.S. 138 parallels the BNSF Railroad line into the city of Sterling. The route veers west along Broadway Street to split into a one-way couplet of 4th Street south and 3rd Street east to U.S. 6 (Chestnut Street). Photo taken 04/22/17.
Chestnut Street used to carry both Business Loop I-76 and U.S. 6. The business route was decommissioned within the Sterling city limits by 2007. Photo taken 08/29/04.
U.S. 138 ends at the westbound turn of U.S. 6 from Chestnut Street onto 4th Street. Colorado 14 ties into the US highway two blocks south at Main Street, while U.S. 6 eastbound ascends across the BNSF Railroad toward Interstate 76. Photo taken 04/22/17.
The CO 14 Sterling S-Curve project will construct a new alignment for Colorado 14 southwest to Main Street at Division Avenue. The project will also convert 4th Street to two-way traffic for U.S. 6 as it leads south to Division Avenue. Photo taken 04/22/17.
Business Loop I-76 overlapped with U.S. 6 southwest to Brush and east to Interstate 76 at Exit 125. Photo taken 08/29/04.

Cedar Street south at the junction with U.S. 138 and U.S. 385 in Downtown Julesburg. A California style cutout for U.S. 138 likely dates from the original establishment of the route in Colorado. The U.S. 385 marker is someone younger, but still quite vintage. Photo taken 09/05/05. Second photo taken 04/22/17.
