Sheridan to Kemmerer: Wyoming's Wild West Road Trip Guide

The drive from Sheridan, WY to Kemmerer, WY follows the historic Lincoln Highway (US-30) and I-80, a route once called the 'Main Street of America.' This 380-mile journey crosses the Continental Divide at 7,000 feet and passes through the ghost towns of South Pass City. The road was originally graded in 1913, making it one of the oldest transcontinental routes in the US. Today, it offers a mix of high desert plains, mountain passes, and fossil-rich badlands. The drive typically takes 6-7 hours without stops, but you'll want to allocate a full day to explore the best stops along the way.

The most direct route from Sheridan to Kemmerer is via I-90 west to Buffalo, then US-16 south to I-25, followed by I-80 west to Kemmerer. Alternative scenic routes include WY-487 south through Shirley Basin. Key metrics: distance 380 miles, driving time 6.5 hours, fuel cost approximately $65 (based on $3.50/gallon and 25 mpg).

• Major highways: I-90, I-25, I-80, US-30
• Top fuel stops: Rawlins (mile 230), Rock Springs (mile 310), Evanston (mile 350)
• Cell coverage: Good along interstates, spotty in mountain passes (especially between Elk Mountain and Rawlins)
• Recommended departure: Early morning (6-7 AM) to avoid afternoon thunderstorms

Road conditions on I-80 are generally excellent, but high winds near Rawlins and Laramie can be dangerous for high-profile vehicles. Winter travel requires chains or snow tires. Summer brings sudden hailstorms. Use rest areas every 2 hours to combat fatigue—try the Elk Mountain Rest Area (mile 255) for panoramic views.

• Rest stops: 7 official rest areas along the route
• Family-friendly: Fossil Butte National Monument offers junior ranger programs; the Wyoming Frontier Prison Museum in Rawlins is a hit with older kids
• Pet-friendly: All rest stops have pet areas; the Saratoga Hot Springs (a slight detour) allow dogs in outdoor pools

The route offers dramatic transitions from the Big Horn Mountains to the Red Desert and finally the Fossil Butte National Monument. In spring, wildflowers carpet the Shirley Basin; in fall, the aspen groves near Elk Mountain turn golden.

• Key geological feature: The Continental Divide at Rabbit Ears Pass (elevation 7,300 ft)
• Wildlife sightings: Pronghorn antelope, sage grouse, and occasionally moose near Encampment
