点评:The Hoover Dam Bypass is the O'Callaghan-Tillman Memorial bridge which was built some years ago to alleviate traffic congestion on the old road atop the dam itself. The high arch of the bridge is in itself a fantastic sight from down at bridge level. But the main attraction is the pedestrian walkway along the north (dam-facing) side of the highway bridge.
First of all, note that it is *really* high. This is definitely not a place to go for anyone who has no head for heights. The bridge is solid, but the wind can be quite strong at its altitude.
The parking area for the bridge is after the dam's security checkpoint and is easy to miss. About half a mile beyond the checkpoint, look for a sign to the "bridge scenic view" pointing to the right. The parking lot is good sized, but can still be crowded. There are public restrooms there. Beyond the parking lot, a long zigzag ramp (with bypassing stairs) leads up to the bridge level. Along the way are interpretive panels about the men for the whom the bridge is named as well as information about the design and building of the bridge itself.
Your reviewer doesn't mind heights much, but the high winds and the highway traffic whizzing by just a few feet away were constant distractions. Nevertheless, the most excellent view down to Hoover Dam was absolutely worth the effort. Watch for the panels in the walkway: there is one for the center of the span, and another for the border between Nevada and California. Also, if you visit later in the afternoon, the shadow of the bridge itself will fall on the dam, adding additional visual interest.

首先,请注意,它真的很高。对于那些恐高的人来说,这绝对不是一个好去处。这座桥很坚固,但在这个高度,风可能相当大。
大桥的停车区位于大坝安全检查站后面,很容易错过。在检查站后约半英里处,寻找指向右侧的“大桥风景”标志。停车场很大,但仍然很拥挤。那里有公共卫生间。停车场外面,一条长长的之字形坡道(有旁路楼梯)通向桥面。沿途有解说牌,介绍这座桥以谁的名字命名,以及关于桥本身的设计和建造的信息。
您的评论者并不介意高处,但几英尺外疾风和呼啸而过的高速公路交通不断分散您的注意力。尽管如此,俯瞰胡佛大坝的最美景色绝对值得付出努力。注意人行道上的面板:一个是跨度中心,另一个是内华达州和加利福尼亚州的边界。此外,如果您下午晚些时候参观,大桥本身的阴影会落在大坝上,增加额外的视觉趣味。
