During the 1920s and ‘30s Route 66 alignments were often primitive, narrow roads. Finding and driving these old alignments can be fun, challenging or both. And these older sections of the Mother Road provide an inkling of what cross-country travel was like decades ago.Learn More
Rock Creek Bridge
Put in place in 1921, the charming Rock Creek Bridge is one of the state’s best remaining examples of the steel-truss architecture that was popular in the pre-World War II era. It originally served the Ozark Trail, a network of locally maintained roads and highways that existed before the federal highway system. The bridge became part of Route 66 in 1926 before being bypassed in 1952. It’s still open to traffic but has a 4-ton weight limit and a 7.2 feet height limit — and it’s quite a bit narrower than most drivers are used to these days.
