英国将在福斯海口上修建一座福斯新桥(Forth Replacement Crossing),以便适应迅速增长的交通量。福斯新桥为双索面中央布置的三塔斜拉桥,采用(650+650)m的主跨跨越2个主航道,该桥设计的独特之处是在主跨跨中将部分斜拉索交错锚固,以此方式约束中塔。该桥有望成为21世纪的标志性工程,与附近建于19世纪和20世纪的2座被列为A级的桥梁同样具有历史意义。该项目在2011年开工,计划2016年建成。
Britain will build a Forth Replacement Crossing at Flowserve Seaport to accommodate the rapidly growing volume of traffic. Flowserve Newbridge is a three-pylon cable-stayed bridge centered on the double cable plane. The main span of (650 + 650) m spans two main channels. The unique design of this bridge is the partial cable-stayed Cable interlaced anchoring, in this way constraints tower. The bridge is expected to be a landmark of the 21st century and as historic as the 2 A-rated bridges built in the 19th and 20th centuries nearby. The project started in 2011 and is scheduled to be completed in 2016.
