Travel directions

SH 63 begins in the hamlet of Anton at an intersection with US 36, 150 miles east of Denver. The road then heads straight north across the barren High Plains. There is only one other village between the start and end point, Akron, where the US 34 crosses. Just before Atwood there is a connection with Interstate 76, after which the road ends in the village of Atwood on US 6.


SH 63 is one of the original state highways from the 1920s. SH 63 originally started in Haswell and went to Atwood. In 1946 and 1954 the route was shortened to its current length. The road was then asphalted, which was completed in 1961.

SH 64 begins in the village of Dinosaur, near the Utah state border, where it intersects US 40. From Dinosaur, the road heads south first, then east through the mountainous desert to Rangely. The road then follows the elongated valley of the White River to the east. The mountains in the area are up to about 2,500 meters high, the valley is at an altitude of 1,600 to 1,800 meters. There are really only two places on the route, SH 64 already ends before Meeker on SH 13.


SH 64 is one of the original state highways from the 1920s. The road originally started on the Utah state border southwest of Dinosaur, so it didn’t pass through that place. In 1946 the starting point was changed to US 40 in Dinosaur. The road was paved during the 1940s and 1950s, which was completed in 1955.

The road is not very important for through traffic, but it is the main east-west connection in the sparsely populated Rio Blanco County. This county is named after the Spanish name of the White River along which SH 64 runs.

Traffic intensities

1,600 vehicles drive daily between Dinosaur and Rangely, peaking at 5,700 vehicles in Rangely. 1,000 vehicles a day travel between Rangely and Meeker.

State Route 65, commonly known as State Highway 65 or SH 65 is a state route in the U.S. state of Colorado. The road forms a north-south route through the Rocky Mountains, from near Delta to I-70 west of Mesa. SH 65 is 99 kilometers long.

Travel directions

SH 65 through Plateau Creek Canyon.

East of the small town of Delta, SH 65 begins at an intersection with SH 92. The road heads north through a valley with fairly scattered buildings. The first part has few differences in height and gradually rises from 1,600 to 1,900 meters. The road then leads over the Grand Mesa, a broad ridge. SH 65 rises here to 3,304 meters above sea level. However, the mountain pass is flattened, with no expansive views due to the forestation and the fact that there are no higher mountains in the area. The road then descends again to the village of Mesa, which is located at an altitude of 1,600 meters. North of Mesa, SH 65 abruptly turns west and follows the deep canyon of Plateau Creek. This is one of the most beautiful roads in Colorado through the deep canyon with steep walls. At one point, there is only a 200-foot-wide and 200-foot-high ridge between SH 65 and old US 6. Shortly thereafter, SH 65 terminates at a junction with Interstate 70.


SH 65 is one of the original state highways of the 1920s. In 1947 the road was paved between Delta and Cedaredge. In the first half of the 1950s, the section between US 6 (now also I-70) and Mesa was paved. The last part of the Grand Mesa was paved in the mid-1960s.

Traffic intensities

Every day, 7,000 vehicles drive near Delta, dropping to 2,300 vehicles in Cedaredge and 500 vehicles across the Grand Mesa. The section through the Plateau Creek Canyon has 2,000 vehicles per day.

According to ACRONYMMONSTER.COM, State Route 66, commonly known as State Highway 66 or SH 66 is a state route in the U.S. state of Colorado. The road forms an east-west route through the Front Range north of Denver, between Lyons and Platteville. The largest city on the route is Longmont. SH 66 is 37 kilometers long.

Travel directions

SH 66 begins just east of Lyons at the base of the Rocky Mountains at an intersection with US 36. The road heads due east for its entire route, passing through the urbanized Front Range region, north of Denver. The road passes along the northern edge of the larger city of Longmont. Near Mead one crosses Interstate 25. Further east on the prairies, SH 66 ends at Platteville on US 85.


SH 66 is one of Colorado’s original 1920s state highways. The road originally ran from Estes Park in the Rocky Mountains to then US 87 (current US 287) in Longmont. The section further east to Platteville was not a state highway at the time. The road originally went through the village of Hygiene to Longmont. In 1939, SH 66 was extended from Longmont to US 85 at Platteville and the road was realigned in 1946 to run more directly from Lyons to Longmont, no longer via Hygiene. The easternmost part, between the present-day junction with I-25 and US 85 at Platteville, was not paved until the late 1950s.

Beginning in 1967, US 36 crossed the Denver-Boulder Turnpike and was extended to Estes Park, running over SH 66 between Estes Park and Lyons. In 1968, SH 66 west of Lyons was largely abandoned in favor of US 36, but a small section in Estes Park remained part of SH 66 until 2007. The area around SH 66 has been urbanized since the 1990s, the City of Longmont has grown toward SH 66.

Traffic intensities

Every day, 7,000 to 12,000 vehicles travel between Lyons and Longmont, increasing to 25,000 vehicles along Longmont and 14,000 vehicles until the junction with I-25. East of I-25, 6,000 to 8,000 vehicles drive as far as Platteville.
