Spanning the North Canadian River, as it empties into Lake Overholser, this is a combination Parker through-truss and pony truss bridge. It is the largest truss bridge on Route 66 in Oklahoma, from its construction era.
Construction of this bridge began in 1924 along Oklahoma Highway 3, known as Postal Road, which ran from Ft. Smith, Arkansas to Texola at the Texas Panhandle. In 1926, the U.S. Bureau of Public Roads established a nationwide system of highways, and they re-designated this section of Highway 3 as part of their U.S. Highway 66. This designation remained until 1958, when larger vehicles made the 20 foot wide bridge roadway less suitable to cross-country travel. A new section of Highway 66 was constructed just north of the bridge, which exists today. The bridge remains in use for local traffic.
This bridge was placed on the National Register of Historic Places in 2004 (#04000133). In 2008, after 84 years of traffic, the bridge was closed to vehicular traffic for much needed rehabilitation, but remained open to pedestrians. It re-opened in October 2011 after a $4 million renovation, with a new concrete roadbed and some truss replacement.
The bridge is 748 feet long, with a 20 ft. wide roadbed. The head clearance at each end is shown as 12 feet 4 inches. The bridge is steel, mounted on concrete piers which are located where each span joins. The piers consist of two concrete posts connected by a poured panel of concrete. The center of the bridge has four Parker through-trusses each with eight panels, 18 feet long, 25 feet high at the center. At each end of the bridge is one camelback Warren pony truss - a lower, open truss, each containing five panels and 80 feet in length. These end trusses are ten feet high at the center. A lattice steel handrail runs the length of the bridge on the north and south sides, for pedestrian use, but there is no designated pedestrian walkway.
To view the bridge up close, turn off N.W. 39th Street (West of N. Council), onto Overholser Drive, just east of the bridge. Turn left onto N. Eagle Lane, and right onto a paved path that will lead to a parking area south of the east end of the bridge. Approximate coordinates shown below.
