Route description

Colorado

I-70 at its interchange with I-76

I-76 begins at an interchange with I-70 in Arvada. From I-70, the freeway heads east to an exit at SH 95, known as Sheridan Boulevard. The route heads northeastward across US 287, known as Federal Boulevard, to an interchange with I-25. Running roughly parallel to the nearby Clear Creek, I-76 meets another interchange with Interstate 270 in North Washington, Colorado, where the Clear Creek joins the South Platte River, which is crossed by I-76. After an interchange at SH 224, I-76 joins US 85 and US 6 at Brighton Boulevard. Past Derby, US 85 veers away from I-76 at Dayton Way. The combined routes of US 6 and I-76 head northeastward, crossing SH 2, named Sable Boulevard, before meeting an exit at E-470, a toll road. Past E-470, the freeway exits the Denver-Aurora metropolitan area.

Passing just west of Barr Lake, the freeway heads northeastward east of Brighton. Near Lochbuie, the freeway crosses SH 7 before crossing into Weld County. I-76 meets SH 52 in Hudson, the next city along the freeway. Past Hudson, the combined routes of US 6 and I-76 turn slightly eastward into Keenesburg, which is served by a business loop (I-76 BUS). I-76 then turns northeast and east into Roggen, where it meets County Road 73. The highway heads away from the farmland it was formerly running through and traverses a large grassland area. Just south of the Empire Reservoir, the freeway turns back east, crossing into Morgan County within circular fields. Heading east, I-76 heads into Wiggins, near which I-76 joins US 34. The three combined routes head east through farms.

I-76 near Brush

The freeway heads east toward Fort Morgan, spawning another business loop that carries US 34 away from I-76. The freeway heads east into Fort Morgan, meeting SH 52, now running again near the South Platte River. Still running between the South Platte River to the north and its business loop to the south, I-76 heads just north of Brush, where it meets a cloverleaf interchange with SH 71. US 34 veers away from the business loop as I-76 turns back east, crossing over the business loop, which does not terminate at the freeway. I-76 BUS carries US 6 toward Hillrose. Bypassing that city, I-76 traverses northeast into Washington County, with farms to the north along the river and grasslands to the south. Passing the Prewitt Reservoir, the freeway heads into Logan County. Heading northeasterly, the route crosses SH 63, which serves Atwood. I-76 BUS then enters Sterling, which is near I-76. The business loops turns abruptly east within the city, carrying US 6. US 6 continues past the interchange with the business route.

I-76 continues parallel to the South Platte River, surrounded by farms to the northwest and plains to the southeast. Northwest of the river is US 138, which serves several towns bypassed by the freeway. I-76 has an exit at SH 55 which serves the town of Crook. With farms on the south part of the freeway as well, I-76 enters Sedgwick County, crossing SH 59 which heads to Sedgwick. The freeway then veers eastward before turning back northeast toward Julesburg. I-76 comes to an exit at U.S. Highway 385, which heads northwest to Julesburg. I-76 then heads northeast to the Nebraska state line.^{[3] [4]}

Nebraska

In Nebraska, I-76 stretches just over two miles (5 km). It is signed as a north–south direction, as opposed to the east–west designation in Colorado. Its entire route is located in Deuel County, parallel to the South Platte River and U.S. Highway 138. Its only interchange is at Interstate 80, numbered exit 102 based on I-80's mileage.

History

I-76 exit along E-470

Until 1975, both the western segment of Interstate 76 and a portion of the eastern Interstate 76 were signed as Interstate 80S. In July 1976, the already-completed route, I-80S, was renumbered to I-76 in accordance with American Association of State Highway and Transportation Officials (AASHTO) policy to remove the letter suffixes from Interstate routes and to avoid the confusion of this route with Interstate 80. This prompted the replacement of around 500 signs in eliminating I-80S. The number, "76", has an association with 1876, the year Colorado was admitted as a state.

I-76 was conceived in August 1958. The Colorado portion was planned and built first. In December 1969, the Nebraska Department of Roads worked together with the Colorado Department of Highways to open a three-mile (5 km) long route connecting Interstate 80 with the rest of I-80S in Colorado.^[1] The original western terminus of I-76 was at I-25, as planned. The western extension to Interstate 70 was built in the late 1980s and early 1990s. By its completion in November 2002, the total cost was about $45.5 million.^[1]

In 1968, Interstate 25 and U.S. Highway 85 was open to the general traffic to the Denver vicinity after all the structures located throughout the route were completed, as well as meeting the criteria of the Interstate standards. Structures connected several interchanges; each one connecting Interstate 270, U.S. Highway 85, Dahlia Street, Washington Street, 74th Avenue, and York Street. The completion also included structures in which each cross the Burlington Canal, Platte River, and the Union Pacific Railroad. By October 24, 1970, the route was open to traffic from Sedgwick to Julesburg, as well as the completion of the route, connecting from its western terminus of I-25 in Colorado to its eastern terminus at I-80 near Big Springs, Nebraska.^[1]

Beginning in 1990, six additional miles were planned and constructed west of I-25. By October 2002, all of I-76 was open, and the highway reached Interstate 70 at Arvada, Colorado, which is now the current western terminus of I-76.^[1]
