In avalanche forecasting, the concept of "bridging" refers to the point in time when the strong snow that overlies a weak layer becomes strong enough that it "bridges" over the weakness. The idea here is that when this point occurs, the strong snow will carry the weight of a person and prevent their force from penetrating through to the weak layer. The strong snow is the "bridge." So then, bridging strength refers to the strength of the bridge.  3, record 1, English, - bridging%20strength

bridging: The ability of a relatively stiff (strong) slab to spread increased load (like that of a person or group) over a wider area, making the onset of an avalanche less likely.  4, record 1, English, - bridging%20strength

... when the term "bridging" is used it implies a weak layer underneath a stronger layer which is at least somewhat supportable. The question of whether the bridging is consistently strong enough to be safe to travel on is a difficult one.  5, record 1, English, - bridging%20strength

Examples: A hard wind slab that exhibits high bridging strength. Hard slabs tend to have more bridging strength. The slabs above these weak layers vary in density and apparently the bridging strength is good. The bridging strength above this layer appears good.  6, record 1, English, - bridging%20strength

Dans les sources consultées, dans le domaine des avalanches, on fait appel à la transposition pour traduire «bridging strength», on obtient alors : neige, croûte ou couche de neige portante ou encore, manteau neigeux portant. Lorsque «bridging strength» est accompagné d'un qualificatif, il est alors possible de le traduire par portance + qualificatif : ainsi, on parlera de la bonne (ou faible) portance du manteau neigeux.  1, record 1, French, - cro%C3%BBte%20portante

[...] on entend par croûte une couche superficielle durcie sur quelques centimètres (de 1 à 5 cm), dont la portance est faible, c'est-à-dire que la croûte casse sous le passage d'un skieur.  2, record 1, French, - cro%C3%BBte%20portante

En France, le terme «portance» n'est pas utilisé. Ceci dit, s'il l'était, il serait relatif à la couche de surface du manteau neigeux. [source : spécialiste de risques d'avalanche, France.]  1, record 1, French, - cro%C3%BBte%20portante

Rain fell as high as 1700 m in some areas, soaking the upper snowpack. Expect a raincrust to form below this elevation as temperatures begin to cool the next few days, and then expect this to be covered with additional new snow. There are a few weak layers in this storm snow and, while warm temperatures are helping heal these weaknesses, whumpfing and cracking was still reported in the Kootenay Pass area on a north facing slope at 2100 m. For the most part new snow is sticking well to the Christmas crust buried 50-70 cm deep. This crust is providing a good bridging layer for the weak facet and surface hoar crystals below the crust, but this layer still remains a concern.  1, record 2, English, - bridging%20layer

In avalanche forecasting, a bridging layer [= une couche dure] is a layer of strong (hard) snow that is often quick thick. Once a layer gets to a certain thickness and hardness, it has enough strength to absorb the load that is applied from above, thus preventing this load from triggering a weakness underneath this "bridge." If ever the "bridge" fails then the result is normally a very large avalanche.  2, record 2, English, - bridging%20layer

En France, un manteau neigeux ou une couche de neige portante n'est pas nécessairement stable. Quand on dit, en France que «la neige porte», cela signifie qu'on ne s'y enfonce pas, notamment à pied. Ainsi une plaque de neige dure est portante, mais elle peut être instable. En France : on n'utilise pas le terme «portance». Ceci dit, s'il était utilisé, il serait relatif à la couche de surface du manteau neigeux.
