near the city is the junction of two major highways: us 385 and i-80. this junction is about halfway between cheyenne, wyoming, and north platte, nebraska. this location has encouraged the growth of sidney as a major transportation service area on the interstate highway. because the i-80/us 385 interchange is many miles southeast of the town center, a new commercial area has developed. this are includes truck stops, convenience stores, shopping centers, motels, restaurants, and other commercial enterprises.
