M-69 (Michigan Highway)
M-69 is an east–west state trunkline highway in the Upper Peninsula (UP) of the U.S. state of Michigan. It connects with US Highway 2 (US 2) on both ends in Crystal Falls and near Bark River. In between, the highway runs for in rural UP forest lands. Before the creation of the U.S. Highway System, the current M-69 was a portion of M-12. The original M-69 was replaced by US 102 and the M-69 designation was reused on a section of M-12 not replaced by US 2. Further changes to the current highway truncated it for three decades. The eastern section removed from M-69 was given the County-Designated Highway designation G-30 until the change was reversed. In 2002, the historic Paint River Bridge in Crystal Falls was rehabilitated, repairing it and restoring it to the original appearance. Route description M-69 starts at the intersection of 5th Street and Superior Avenue in Crystal Falls, where it meets US 2/ US 141. The Iron County Courthouse is locat ...

M69 Motorway
The M69 is a dual three lane dual carriageway motorway in Leicestershire and Warwickshire, England. It runs between junction 21 of the M1 near Leicester and junction 2 of the M6 near Coventry. It opened in 1977. History The motorway, also known at the time as the 'Coventry – Leicester Motorway' was completed in 1977 following a public inquiry in 1972.The Motorway Archive – M69
It took traffic from the A46, which was subsequently downgraded.

Gulf Intracoastal Waterway
The Gulf Intracoastal Waterway is the portion of the Intracoastal Waterway located along the Gulf Coast of the United States. It is a navigable inland waterway running approximately from Carrabelle, Florida, to Brownsville, Texas. The waterway provides a channel with a controlling depth of , designed primarily for barge transportation. Although the U.S. government proposals for such a waterway were made in the early 19th century, the Gulf Intracoastal Waterway was not completed until 1949. EHL & WHL mileages Locations along the Gulf Intracoastal Waterway are defined in terms of statute miles (as opposed to nautical miles, in which most marine routes are measured) east and west of Harvey Lock, a navigation lock in the New Orleans area located at . The Hathaway Bridge in Panama City, Florida, for example, is at mile 284.6 EHL (East of Harvey Lock). The Queen Isabella Causeway Bridge at South Padre Island is at mile 665.1 WHL (West of Harvey Lock). Connecting waterways Th ...

Miles M
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of distance; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the British Commonwealth and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly . With qualifiers, ''mile'' is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile, such as the nautical mile (now exactly), the Italian mile (roughly ), and the Chinese mile (now exactly). The Romans divided their mile into 5,000 Roman feet but the greater importance of furlongs in Elizabethan-era England meant that the statute mile was made equivalent to or in 1593. This form of the mile then spread across the British Empire, some successor states of which conti ...

Messier 69
Messier 69 or M69, also known NGC 6637, is a globular cluster in the southern constellation of Sagittarius. It can be found 2.5° to the northeast of the star Epsilon Sagittarii and is dimly visible in 50 mm aperture binoculars. The cluster was discovered by Charles Messier on August 31, 1780, the same night he discovered M70. At the time, he was searching for an object described by Nicolas-Louis de Lacaille in 1751–2 and thought he had rediscovered it, but it is unclear if Lacaille actually described M69. This cluster is about 28,700 light-years away from Earth and from the Galactic Center, with a spatial radius of 45 light-years. It is a relatively metal-rich globular cluster that is a likely member of the galactic bulge population. It has a mass of with a half-mass radius of , a core radius of , and a tidal radius of . Its center has a bright luminosity density of ·pc−3 (meaning per cubic parsec). It is a close neighbor of its analog M70 – possibl ...

M69 Grenade
The M67 grenade is a fragmentation hand grenade used by the United States military. The M67 is a further development of the M33 grenade, itself a replacement for the M26-series grenades used during the Korean and Vietnam Wars, and the older Mk 2 "pineapple" grenade used since World War I. Overview The M67 grenade has a spheroidal steel body that contains of composition B explosive. It uses the M213 pyrotechnic delay fuze. The M67 grenade weighs in total and has a safety clip to prevent the safety pin on the grenade from being pulled accidentally. The safety pin prevents the safety lever, or "spoon" on the grenade from moving and releasing the spring-loaded striker which initiates the grenade's fuse assembly. The M67 is typically known as a "baseball" grenade, because it is shaped like a ball that can be easily thrown. According to the FY2021 US Army Justification, the average cost of a single M67 grenade is around 45 US dollars. The M67 can be thrown by the average male so ...
