Constructed in 1924 and added to the National Register of Historic Places in 1995, Bridge No. 18 at Rock Creek is an excellent example of a parker through truss bridge on Route 66 in the state. This type of bridge was used extensively along the route during the first part of the 20th Century. It also originally served the Ozark Trail, a network of locally maintained roads and highways.
Rock Creek bridge was bypassed by Route 66 in 1952. The bridge did remain in use until recently. While still structurally sound, it is closed to vehicular and pedestrian traffic. The city of Sapulpa plans to turn the area east of the bridge into a park and use the bridge as a centerpiece, attracting domestic and international travelers.
