Phrases & compounds
Cantalever bridge — a bridge in which the principle of the cantalever is applied. It is usually a trussed bridge, composed of two portions reaching out from opposite banks, and supported near the middle of their own length on piers which they overhang, thus forming cantalevers which meet over the space to be spanned or sustain a third portion, to complete the connection.
