Coconino County is a county in the North-Central part of the U.S. state of Arizona. Its population was 145,101 at the 2020 census. The county seat is Flagstaff. The county takes its name from Cohonino, a name applied to the Havasupai people. It is the second-largest county by area in the contiguous United States, behind San Bernardino County, California.

Cameron is a census-designated place (CDP) in Coconino County, Arizona, United States, on the Navajo Nation. The population was 885 at the 2010 census. Most of the town's economy is tourist food and craft stalls, restaurants, and other services for north–south traffic from Flagstaff and Page. There is a ranger station supplying information and hiking permits for the Navajo Nation. There is also a large craft store run by the Nation itself. It is named after Ralph H. Cameron, one of the two senators first appointed to U.S. Congress for Arizona, upon its federal recognition of statehood.
Navajo Bridge is the name of twin steel spandrel arch bridges that cross the Colorado River in the Grand Canyon National Park in northern Coconino County, Arizona, United States. The newer of the two spans carries vehicular traffic on U.S. Route 89A (US 89A) over Marble Canyon between Bitter Springs and Jacob Lake, allowing travel into a remote Arizona Strip region north of the Colorado River including the North Rim of Grand Canyon National Park.
Northern Arizona is an unofficial, colloquially defined region of the U.S. state of Arizona. Generally consisting of Apache, Coconino, Mohave, Navajo, and Yavapai counties, the region is geographically dominated by the Colorado Plateau, the southern border of which in Arizona is called the Mogollon Rim.
The Arizona Strip is the part of Arizona lying north of the Colorado River. Despite being larger in area than several U.S. states, the entire region has a population of fewer than 10,000 people. Consisting of northeastern Mohave County and northwestern Coconino County, the largest settlements in the Strip are Colorado City, Fredonia, and Beaver Dam, with smaller communities of Scenic, Littlefield and Desert Springs. The Kaibab Indian Reservation lies within the region. Lying along the North Rim of the Grand Canyon creates physical barriers to the rest of Arizona. Only three major roads traverse the region: I-15 crosses the northwestern corner, while Arizona State Route 389 and U.S. Route 89A cross the northeastern part of the strip, and US 89A crosses the Colorado River via the Navajo Bridge, providing the only direct road connection between the strip and the rest of the state. The nearest metropolitan area is the St. George, Utah metro area, to which the region is more connected than to the rest of Arizona.

The Bollman Truss Railroad Bridge across the Little Patuxent River at Savage, Maryland, is one of the oldest standing iron railroad bridges in the United States and the sole surviving example of a revolutionary design in the history of American bridge engineering. The 160-foot (48.8 m) double-span was built in 1852 at an unknown location on the main line of the Baltimore and Ohio Railroad. It was moved 35 years later to its present location, where it replaced the very first Bollman bridge. Today, it carries the Savage Mill Trail.
State Route 128 (SR-128) is a 44.564-mile-long (71.719 km) state highway in the U.S. state of Utah. The entire length of the highway has been designated the Upper Colorado River Scenic Byway, as part of the Utah Scenic Byways program. This road also forms part of the Dinosaur Diamond Prehistoric Highway, a National Scenic Byway.

State Route 79 and State Route 89 are both former sections of US 89.
The Cedar Canyon Bridge is a steel arch highway bridge on US 60 near Show Low, Arizona. The 180-foot (55 m) span ribbed girder arch bridge was built in 1937–38 with a total length of 250 feet (76 m). The 24-foot-wide (7.3 m) bridge was substantially widened and upgraded in 1994, using the identical arch from the Corduroy Creek Bridge to double the width of the bridge while rehabilitating the deck structure.
The Corduroy Creek Bridge was a steel arch highway bridge on US 60, located near Show Low in Navajo County, Arizona.
Chevelon Creek Bridge is a historic road bridge located about 12 miles (19 km) southeast of Winslow, in Navajo County, eastern Arizona, United States. It is a steel Warren Pony truss bridge over Chevelon Creek, built on the first permanent road connecting Holbrook, the seat of Navajo County, and Winslow. When built, the road was regionally important in northern Arizona as well as being a segment of an early national highway at the time automobile traffic was growing and national roads were first being formed. The bridge was listed on the National Register of Historic Places in 1983 for being a rare design in Arizona, part of an early transnational roadway, one of the first bridges built by Arizona after statehood in 1912, and being in nearly original condition.
The Midland Bridge Company is a firm based in Kansas City, Missouri, United States, that has built numerous bridges. Several of its works are listed on the U.S. National Register of Historic Places (NRHP).
The Rockville Bridge spans the east fork of the Virgin River in Rockville, Utah, United States. The bridge was built for the National Park Service in 1924 to provide a link between Zion National Park and the North Rim area of Grand Canyon National Park. The new bridge allowed motorists to take a circular tour of the national parks in southern Utah and northern Arizona. The Rockville route was superseded in 1928 by the construction of the Zion-Mount Carmel Highway.
The Black Suspension Bridge spans the Colorado River in the inner canyon of Grand Canyon National Park. The span length is 440 feet (130 m). The bridge is part of the South Kaibab Trail and is the river crossing used by mules going to Phantom Ranch. The Black Bridge and Silver Bridge, located about 700 metres (2,300 ft) downstream, are the only spans in hundreds of river miles.
The Ocean-to-Ocean Bridge is a through truss bridge spanning the Colorado River in Yuma, Arizona. Built in 1915, it was the first highway crossing of the lower Colorado and is the earliest example of a through truss bridge in Arizona. It is also the only example of a Pennsylvania truss within Arizona. Originally the bridge carried the transcontinental Ocean-to-Ocean Highway and later carried its successor, US 80 until a new bridge was built to the west in 1956. Between 1988 and 2001, the bridge was closed to vehicular traffic and only traversable by pedestrians and bicyclists. After a major restoration, the bridge was rehabilitated and reopened to vehicular traffic in 2002, with a re-dedication by the Quechan nation and Yuma Crossing National Heritage Area. The bridge became part of Historic US 80 in 2018.
