直到2018年，您可以在卡姆登县J号州立大学的密苏里州中部开车，并在小悬架桥上越过小妮格亚河。小妮格亚河（Niangua River）觅食奥扎克斯（Ozarks）湖，这是一个庞大的水体，于1931年由巴格内尔大坝建造而成。

这lake extends far west and north from the dam. Part of the project included construction of bridges across its tributaries, which in some areas became much wider parts of the new lake and more difficult to cross. The Little Niangua River Bridge (aka Green’s Mill Bridge) was built in 1933. It is one of a short list of self-anchored suspension bridges built at that time, and one of the few structures of its type remaining.
这main span of the bridge is 225’ long. It has a steel grid deck and wire parallel strand cables. Bridge construction was funded in 1931, in part as mitigation for building of the Bagnell Dam, which flooded the river further east of the bridge site. Representatives from Camden County worked with the Missouri State Highway Department (MSHD) for the bridge design and construction. The Department consulted with theJohn A. Roebling’s Sons Company新泽西州特伦顿的关于建造悬架桥的信息。目前尚不清楚设计师如何最终获得悬架桥，因为当时通常会选择某种类型的桁架。但是，在咨询罗布林公司时，最终设计中有一些布鲁克林大桥的淡淡，这就是建造的。
这桥was determined eligible for listing on the National Register of Historic Places as a自行裁员桥梁的全国重要例子。At the time of construction, it was one of four self-anchored suspension spans. The others are the三姐妹越过匹兹堡的阿勒格尼河。这些桥梁仍在使用。
这小内古河is still standing, but unfortunately time has taken its toll. Regular bridge inspections found increasing deterioration, to the point where Missouri DOT made the decision to replace it. Because the structure has potential historic value, Missouri DOT is offering the bridge for free to organizations or individuals who can propose reuse in place.
十字路口位于奥扎克山（Ozark Hills）的乡村和滚动区域。尽管桥现在关闭，但您可以在Google Street View的帮助下“虚拟”驾驶，该景观在2018年之前有照片。这是一个惊人的驱动器。路线J穿越美丽而偏远的地形，具有田园般的树林和滚动的农田。您在照片上向东“开车”，突然间桥出现了。令人震惊的是。悬挂桥的形式是我们与大城市联系在一起的东西，但这是在树林和农场中间的这座小小的，不起眼的桥梁。该结构是叠加在农村景观上的大城市的令人回味的混搭。它绝对是一座悬架桥，但它是一座偏远的小桥，看起来像从空间和时间流到另一个地方。
这绿厂的历史桥梁协会希望将密苏里州的报价点付诸实践。它是一个非营利组织，正在寻求保护桥梁。我与协会主席Lonetta Bartell进行了交谈，她分享了一些想法：
格林机桥是五座桥若干之一ucted when the Lake of the Ozarks was created by constructing Bagnell Dam on the Osage River. Each of the five bridges spanned one of the five rivers that shape and send water into the “Dragon Lake” of the Ozarks.
这五个桥梁中有四个已被拆除并取代。格林的磨坊桥是剩下的唯一一座，不再足以适应State Road J. Green's Mill Bridge在河流和湖泊汇合处下游的小妮格亚河上穿过的小妮格亚河。
My family would spend summer vacations at a campground just southwest of the bridge. Mom would take me along with my brothers and sisters to the bridge where I would listen with sincere interest as she shared stories about her childhood and what it was like living in the backwoods of the Missouri Ozark Hills. My mom is now gone. However, I still feel driven to take my own children and grandchildren to the bridge. As we stop to look at the breathtaking scenery that surrounds us, I think of mom as I share with them her stories from days gone by, include my own stories of vacationing here and to teach them a little bit about their heritage. Today I live one mile downriver from Green's Mill Bridge.
我们组建了一个小组来帮助保护桥梁。格林的米尔历史桥公司成立于2018年：
1.在原始位置保存和维护格林的磨坊桥
2.使访客可以使桥和奥扎克斯历史访问
3.支持桥梁工程历史和教育
我们的组织计划将这座桥开发为残障可访问设施。甲板目前是开放的钢网格。我们将铺设回收橡胶，该橡胶被ADA批准为穿越桥梁的人行道。钢炉子的一部分将保留。链环围栏将在原始栏杆内部安装在两侧。将在桥的东北端建造一个庭院和残障停车场，西南端有一个常规的停车场。黄昏到黎明照明将在完整的桥梁上闪耀。
桥梁的使用将用于公众聚会，例如家庭聚会，婚礼，纪念馆，日出或维斯珀教堂的聚会以及筹款活动。列表是无穷无尽的。
我们计划通过提供会员资格和接受捐赠来为该项目提供资金。我们目前正在举办国会大厦运动，以使公司和/或个人承担此规模项目固有的一些持续成本。新利18备用官网登录
该协会在试图保留旧桥时进行了令人印象深刻的任务。子孙后代将欣赏这座古怪而独特的小桥。您可以想象，在Ozark夏季，人们聚集在庆祝活动和庆祝活动的桥梁上。找不到欣赏这个古老而出色的小跨度的更好方法。我们期待着社会的成功。
