Hardy Bridge
Hardy Bridge is a Warren through truss, three- span, two-lane bridge in the western United States. It crosses the Missouri River and is located at milepost 6 on Old U.S. Route 91, about southwest of Cascade, Montana, which is southwest of Great Falls. Constructed in 1931, it was one of many similar bridges built during a great expansion of bridges and roadways in the state of Montana. It was added to the National Register of Historic Places on January 4, 2010. Hardy Bridge is named for the unincorporated small community of Hardy, which is about downstream from the bridge below the Pine Island Rapids. The bridge is located on a northwest-southeast axis in the Adel Mountains Volcanic Field, a spectacularly eroded 75-million-year-old volcanic field; the approximate elevation of the river is above sea level. Description The toll-free bridge is long and is wide. Two lanes of traffic (with a curb but no shoulder) are carried by the bridge. The two longest of its three ...

Missouri River
The Missouri River is a river in the Central United States, Central and Mountain states, Mountain West regions of the United States. The nation's longest, it rises in the eastern Centennial Mountains of the Bitterroot Range of the Rocky Mountains of southwestern Montana, then flows east and south for before entering the Mississippi River north of St. Louis, Missouri. The river drains Semi-arid climate, semi-arid Drainage basin, watershed of more than 500,000 square miles (1,300,000 km2), which includes parts of ten U.S. states and two Canadian provinces. Although a tributary of the Mississippi, the Missouri River is slightly longer and carries a comparable volume of water, though a fellow tributary (Ohio River) carries more water. When combined with the lower Mississippi River, it forms the List of rivers by length, world's fourth-longest river system. For over 12,000 years, people have depended on the Missouri River and its Tributary, tributaries as a source of sustena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I-beam
An I-beam is any of various structural members with an - (serif capital letter 'I') or H-shaped cross section (geometry), cross-section. Technical terms for similar items include H-beam, I-profile, universal column (UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish language, Polish, Bulgarian language, Bulgarian, Spanish language, Spanish, Italian language, Italian, and German language, German). I-beams are typically made of structural steel and serve a wide variety of construction uses. The horizontal elements of the are called flanges, and the vertical element is known as the "web". The web resists shear forces, while the flanges resist most of the bending moment experienced by the beam. The Euler–Bernoulli beam equation shows that the -shaped section is a very efficient form for carrying both bending and shearing (physics), shear loads in the plane of the web. On the other hand, the cross-section has a reduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sun River
The Sun River (also called the Medicine River) is a tributary of the Missouri River in the Great Plains, approximately 130 mi (209 km) long, in Montana in the United States. Geography It rises in the Rocky Mountains in two forks, the North Fork and South Fork, which join in the Helena-Lewis and Clark National Forest above Gibson Reservoir along the county line between Teton and Lewis and Clark counties. It flows E, SE, and E away from the mountains, past Simms, Sun River, and Vaughn and joins the Missouri at Great Falls. The water of the river is used extensively for irrigation, through the Sun River Project of the United States Bureau of Reclamation. The irrigation area covers approximately 92,000 acres (372 km2). The North Fork of the Sun River begins high up in the Bob Marshall Wilderness and flows generally Southward for about until it meets up with the South Fork of the Sun River. Almost immediately the two forks flow into Gibson Reservoir, imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hauser Dam
Hauser Dam (also known as Hauser Lake Dam) is a hydroelectric straight gravity dam on the Missouri River about northeast of Helena, Montana, in the United States. The original dam, built between 1905 and 1907, failed in 1908 and caused severe flooding and damage downstream. A second dam was built on the site in 1908 and opened in 1911 and comprises the present structure. The current Hauser Dam is long and high.''Upper Missouri River Reservoir Fisheries Management Plan, 2010–2019'', Montana Department of Fish, Wildlife and Parks, May 13, 2010, p. 11. The reservoir formed by the dam, Hauser Lake (also known as Hauser Reservoir), is long, has a surface area of , and has a storage capacity of of water when full.''Upper Missouri River Reservoir Fisheries Management Plan, 2010–2019'', Montana Department of Fish, Wildlife and Parks, May 13, 2010, pp. 7, 9.

Lake Helena
Lake Helena is a body of water along Prickly Pear Creek in the Helena Valley of Lewis and Clark County in southwestern Montana. It is in size and is above sea level. History Completion of Hauser Dam on the Missouri River in 1907 created Hauser Lake. In addition, it created an arm of the lake, flooding of Prickly Pear Creek and surrounding wetlands to form Lake Helena. In 1945, a causeway was built to separate the lake from the flooded canyon portion of the old Prickly Pear Creek. The causeway replaced a 1904 combination steel and wood bridge. The steel span was 120' long, and the overall length of the bridge was 520'. The concrete piers of the steel bridge, which was sold for scrap and dismantled in 1952, can still be seen just north of the causeway. Water from Tenmile Creek, Prickly Pear Creek, Silver Creek, and the Helena Valley Irrigation Project flows into the west end of the lake. Lake Helena supported a commercial carp fishery for decades. The marshy west end of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mullan Pass
Mullan Pass is a mountain pass in the western United States, in the Rocky Mountains of Montana. It sits on the Continental Divide on the border between Powell and Lewis and Clark counties at above sea level. Located in the Helena National Forest, the pass is west of the city of Helena. The Northern Pacific Railway (NP) used the pass for its line from Logan to Garrison via Helena, built in 1883. This line was the NP's primary freight route and was also used by their secondary passenger train, the '' Mainstreeter''. The NP also built an alternate line over Homestake Pass, which was used by their primary passenger train, the '' North Coast Limited''. The rail line at Mullan Pass is currently operated by BNSF Railway; it crosses under the pass and the continental divide at via the Mullan Tunnel. The pass was named after Lieutenant John Mullan, the U.S. Army engineer who first crossed the pass on March 22, 1854, and later supervised construction of the Mullan Road, the first ...

Big Belt Mountains
The Big Belt Mountains are a section of the Rocky Mountains in the U.S. state of Montana. Situated mainly in the Helena National Forest, the mountains are used for logging and recreation for the surrounding residents. Nearby are the cities of Helena, Townsend, and White Sulphur Springs, as well as Canyon Ferry Lake and the Missouri River. The highest point in the Big Belt Range is Mount Edith at , while the center of the range is .
