在历史上的某个时期，美国有超过14000座木桥。这些建筑大多建于1825年至1875年之间，用于跨越溪流或河流，旨在抵御恶劣天气。一座无遮盖的木桥可能只有大约20年的寿命，而一座有遮盖的桥可以支撑100多年。即使如此，如果没有维护，它们也不会很好，修复成本可能很高。19世纪中叶，铁取代木材成为首选且更便宜的桥梁建筑材料。这些天来，据信只有不到900座原始的木制覆盖桥梁仍然屹立着。佛蒙特州目前有104座桥，是该国剩余有盖桥梁密度最高的一座。今天照片中的阿隆佐-梅里尔-福斯特（Alonzo Merrill Foster）桥位于佛蒙特州的卡伯特（Cabot）。

At one point in history, the United States had upwards of 14,000 wooden covered bridges. Most of them were built between 1825 and 1875 to cross a stream or river and were intended to withstand the elements. An uncovered wooden bridge may have a lifespan of only about 20 years while a covered bridge could stand for more than a 100. Even still, they don't fare well without upkeep and restoration costs can be high. Iron replaced wood as the preferred and cheaper bridge-building material in the mid-1800s. These days, fewer than 900 of the original wooden covered bridges are believed to still be standing. Vermont currently has 104 of them, the highest density of remaining covered bridges in the country. The Alonzo Merrill Foster covered bridge seen in today's photo can be found in Cabot, Vermont.
