鵜飼い大橋は、岐阜環状線の一部を形成し、千三百有余年の歴史と伝統を誇る長良川の伝統行事「鵜飼い」の開催流域に架けられる橋梁で、その形式は「鵜飼いとともにある橋」「風景との調和」「岐阜のゲート性」「橋の個性」の基本コンセプトに最も適合する鋼５径間連続箱桁橋（右岸側）＋鋼単径間斜張橋（左岸側）としている。
左岸側の斜張橋は、背面に位置する金華山の傾斜に合わせるように75°に傾けた高さ60ｍの主塔から、支間長152.4ｍの単径間を中央１面ケーブルで吊り、バックスティケーブルを橋の左右に展開し、独立したアンカレッジに支持させる特殊な単径間斜張橋を採用している。
本橋は、主塔やケーブルが「鵜を操る鵜匠」を思わせる優雅な姿を備えた橋梁で、夜間には夏冬で色が異なるあでやかで格調高い照明により彩りを添えるなど、新たな河畔景観の創出と長良川観光のパターンを大きく変えることができる。
