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.
In Germany in 1957 the first 380 kV overhead power line was commissioned (between the transformer station and Rommerskirchen). In the same year the overhead line traversing of the Strait of Messina went into service in Italy, whose pylons served the Elbe crossing 1. This was used as the model for the building of the Elbe crossing 2 in the ...

The following is a list of spans, either used for overhead line crossings of rivers, sea straits or valleys, as antenna or for aerial tramways. This list is incomplete ; you can help by adding missing items .
The Bosporus overhead line crossing 1 was the first overhead transmission line crossing the Bosporus. It was inaugurated in 1957 and it is designed and operated for two 154 kV circuits. Although apparently designed for overhead ground wires, none are currently present. The span width is 1,782 m (5,846 ft), clearance over Bosporus is 59 m (194 ft).

The Saint Lawrence River HVDC Powerline Crossing is the crossing of Hydro-Québec's Quebec-New England HVDC transmission line over (and later, under) the Saint Lawrence River between Grondines and Lotbinière, Quebec, Canada. The crossing is remarkable, for being first implemented as an overhead crossing, and then later replaced by a cable tunnel.
