NEXT architects：荷兰梅尔克韦格桥（Melkwegbridge）穿过诺德霍兰德施·卡纳尔（Noordhollandsch Kanaal），将皮尔默伦德（Purmerend）的历史中心与西南边正在不断发展的魏德文内（Weidevenne）地区连接起来，这座桥的规划建设是运河及其周边区域总体规划发展的第一阶段。

NEXT architects: The Melkwegbridge (the Netherlands) crosses the Noordhollandsch Kanaal and connects the historic centre of Purmerend with the growing Weidevenne district in the south-west. The bridge is the first stage in a masterplan for the canal and its periphery.

“设计团队的目标是建设一个具有独特感和标识性的新区域，将其作为新旧中心之间的纽带。”

“The aim of the design team was to create a new area with a specific identity, which could work as a connector between the old and the new centre.”

由NEXT建筑设计事务所设计的这座桥——Melkwegbridge，桥身最引人注目的是一个巨大的拱，距离水面12米以上，与梅尔克韦格路形成一条连续的线，成为城市景观中的一道壮丽风景线。高处的瞭望台让市民可以从日常的生活环境中跳脱出来，领略这座历史名城的风貌。桥下方的自行车道长100米，像钟摆一样跨过水面，考虑到自行车和轮椅所需的最小坡度，所以100米的长度对于这条自行车道来说是有必要的。

The most striking part of the bridge, designed by NEXT architects, is a massive arch which reaches a height of 12m above water level and stands in a continuous line with the Melkweg-road, thus offering an incredible view over the city. The high lookout gives pedestrians the opportunity to take a step back from their daily environment and, on a new level, experience the relation between the new and historic city of Purmerend. The lower bicycle deck is made out of a 100m long bicycle deck that crosses the water like a pendulum. The length of this deck was necessary due to the minimum slope conditions for bicycles and wheelchairs.

将骑行流线和人行流线分开布置，可以使行人以最短的距离走向对岸。这座人行桥重85吨，钢拱架上布置了130级台阶，这使得场地能够保持其空间开放性。12米高的桥拱足够船只从桥下通过，当船只通过时，两侧的自行车道会旋转分开，为船只开路。

Seperating cyclists from pedestrians, gave the opportunity to maintain the direct line of the historics Melkweg (Melkroad) within the bridge. The pedestrian bridge weighs 85 tons, consists of 130 steps and is supported by a steel arch. The design makes it able to retain the spatial openness of the channel and its surroundings. At 12 metres, this arch is high enough to allow boats to pass beneath; The lower deck splits into two parts that revolve open when boats are approaching.

桥的两个部分相互组合形成一个整体，运用了统一的材料和颜色，增强了整体协调性。桥的边缘采用了LED灯光设计，沿着桥排布，这样即便是日落之后也有美丽的夜景可观。

Both bridge sections flow smoothly into each other and form one whole. This unity is enhanced by the continuity of materials and colors. In the edges of the bridge LED lines are applied that follow the contour of the bridge and guarantees a spectacular view on the bridge even after sunset.
