In North American usage, a flyover is a high-level overpass, built above main overpass lanes, or a bridge built over what had been an at-grade intersection.Traffic engineers usually refer to the latter as a grade separation.
An overhead line crossing is the crossing of an obstacle—such as a traffic route, a river, a valley or a strait—by an overhead power line. The style of crossing depends on the local conditions and regulations at the time the power line is constructed.
The clearance for overhead signs is 5.7 metres (18 ft 8 in) and the clearance for the soffit or underside of overpasses is 10 metres (32 ft 10 in). [ 6 ] In South Africa and the southern region of Africa, the minimum vertical clearance of modern bridges is 5 metres (16 ft 5 in), although the legal height limit of road vehicles is still at 4.3 ...
The observer would see a bright object appear in the northwest, which would move across the sky to a point almost overhead, where it disappears from view, in the space of three minutes. The following is a list of tools on a variety of platforms that may be used to predict the pass of an orbiting artificial satellite over a given point on Earth.
The generic term used by the International Union of Railways for the technology is overhead line. [1] It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire.
State Route 88 (SR 88), also known as the Carson Pass Highway, [2] [3] is a state highway in the U.S. state of California. It travels in an east–west direction from Stockton , in the San Joaquin Valley , to the Nevada state line, where it becomes Nevada State Route 88 , eventually terminating at U.S. Route 395 (US 395).
The tollbooths were dismantled, and drivers are no longer able to pay cash at the bridge. Instead, there are cameras mounted onto new overhead gantries located on the Staten Island side. A vehicle without E-ZPass has a picture taken of its license plate and a bill for the toll is mailed to its owner.
Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.
