保定自驾乐探索马岭河大桥的奇迹之旅
在贵州省兴义市，坐落着一座名为马岭河特大桥的壮观建筑，它横跨著名的国家4A级风景区——马岭河大峡谷。这个壮丽的大桥不仅是连接两岸的重要通道，也是观赏瀑布水流的地方。大桥每年都进行维修和改造，以确保其安全与美观。
马岭河特大桥位于兴义市顶效，是2009年8月28日正式合龙的大型工程。这座斜拉桥全长1386米，其中最高塔高达196米。它是目前贵州省内建成的第一座也是最大的一座三跨预应力混凝土双塔双索面斜拉桥。
为了改善交通状况，324国道跨马岭河大桥危桥改造工程（三号大桥）正在进行中。这项工程总投资12.67亿元，主体采用单跨450米的双层钢桁架加劲地锚式悬索橋设计。bridge width of 36.3 meters, with an upper layer of dual carriageway and a lower level featuring tramway in the middle, accompanied by two 6-meter-wide walkways on both sides. The total length is 2912 meters.
