gmp·冯·格康，玛格及合伙人建筑师事务所(gmp)和Leonhardt, Andrä及合伙人工程师事务所(LAP)联合赢得了A1联邦高速公路扩建工程新建北易北和河桥设计竞赛。该项目隶属德国联邦2030交通规划框架之下，建成后两座高耸的桥塔和双斜拉索结构将成为横跨于易北河上的重要地标。

As part of the upgrade of the A1 federal motorway, the new bridge designed by the engineers Leonhardt, Andrä und Partners (LAP) and the architects von Gerkan, Marg and Partners (gmp) replaces the existing bridge across the Norderelbe River. The double cable-stayed bridge with its pylons of different heights will be visible from afar, marking the point at which it crosses the river. The project is included in the Federal Transport Infrastructure Plan for 2030.

河道两岸地形的不同决定了新建大桥桥塔高度和斜拉索跨度的差别，不对称的建筑形式反应了场地的面貌。远景中八座塔桥如同城门般引人瞩目，塔桥从下至上逐渐变细，高速公路两向车道从桥面上通过，从水面上望去，桥梁如同门框矗立于易北河航道之上。

The different spans and pylon heights of the new bridge result from the different widths of the side fields and reflect, in the structure, the asymmetrical situation of the terrain of the two river banks. There will now be eight pylons that create a conspicuous portal from any perspective: both directions of the motorway are flanked left and right by the pylons, which taper at the top; looked at from the water, they appear to be framing the river in sequence.

较高和较矮的两组桥塔上各固定有三组和两组钢缆。桥梁南侧缆索外侧设有与机动车道平行的非机动车道。非机动车道与机动车道之间保持一定距离，同时享有河面的开放视野，作为北易北河和易北河支流两岸自然景区路网的一部分，具有独特的品质。桥梁钢构件银灰色的涂层映射出河面水波、天空和两岸植被的色彩，令整座桥梁更显轻盈精致。新北易北河桥建成后将加入汉堡桥梁的行列，为汉堡城市建造文化增光添彩。

The higher set of pylons holds up three pairs of cables, whereas the lower ones only hold two. On the south side of the bridge, outside the pylons and parallel to the traffic lanes but with a separate construction, runs a pedestrian and cyclist bridge. Its and the open view of the river creates a high-quality crossing, which is an integral part of the pathway system of the local recreation area along the Norderelbe and Dove-Elbe rivers. A bright silvery coating of the building components reflects the color of the water, sky, and vegetation and thereby enhances the elegant appearance of the bridge.

“在汉堡这样拥有很多桥梁的城市中，城市中的桥梁和港口以及易北河上的桥梁不尽相同，后者呈现纯粹工程美学的魅力。即将被取代的北易北河旧桥由Jux和Freese建筑师事务所于1963年设计，其以内敛优雅同时极富识别性的形态备受赞誉。我们将新桥设计定义为一种‘演进’，桥面扩建为八车道的同时还应具有延续场所精神的品质。新建北易北河双塔斜拉索桥在葆有老桥的气质同时，其地标建筑的整体效果得到了强化。”——福尔克温·玛格教授

“In the city of many bridges, the Harbor and Elbe bridges are distinct from those of the inner city due to their fascinating, pure engineering esthetic. The Norderelbe Bridge, which is going to be replaced, as an engineering structure enjoys a great reputation in the eyes of the public due to its restrained elegance and high identity value. This identification with the existing bridge—designed around 1963 by the architects Jux and Freese—has prompted us to look upon the new bridge as an ‘evolution’ that does justice to the requirement for the eight-lane upgrade while, at the same time, continuing the quality ofthe genius loci. The design for the new double cable-stay bridge for motorway BAB 1 picks up on the message of the existing bridge and, at the same time, augments its esthetic effect as a landmark for the Elbe crossing.” — Prof. Volkwin Marg
