U.S. Route 40 marker

The west end of U.S. Route 40 is in the U.S. state of Utah at Silver Creek Junction in Silver Summit(about 20.7 miles (33.3 km) east of Salt Lake City) with Interstate 80. From there it heads southeast through Heber City and east into Colorado on its way to the Mid-Atlantic.

U.S. Route 40 begins at I-80 at Silver Creek Junction in Silver Summit, traveling south-southeast as a full freeway in a broad valley northeast of Park City. At the south end of the valley, Jordanelle Reservoir comes into view and US-40 continues south high on the slope above its western shore while Utah State Route 248 climbs away to the east on the slope overlooking the northern shore. The freeway passes through several large cuttings in the side of the mountains that were dug when US-40 was relocated to make way for the reservoir; Utah State Route 319 provides access down the slope to a state park on the shore of the reservoir. South of the reservoir, the dam is visible on the left and the road loses elevation quickly before abruptly connecting to a (suburban or exurban) non-freeway segment with frequent curb cuts and building frontage. In central Heber, U.S. Highway 189 continues south, but US-40 turns east to leave the city. US-40 continues south and east through mountains and the Uintah Basin to the Colorado border near Dinosaur National Monument.
