Route 66 next hits the town of Sapulpa, OK... Bridge #18 Rock Creek, just west of Sapulpa, OK. An original steel truss bridge built in 1924 along the original Route 66 1926 alignment. It is one of the remaining steel-truss bridges that carried Route 66 in Oklahoma. This particular bridge is a Parker through truss bridge and, as an unusual feature, it has a brick decking (it is paved with red bricks). It is 120 ft. long and 18 ft. wide. Its steel truss has a compound truss and a polygonal top cord which allow its long span. It was built in 1924, just two years before Route 66 was created, and was originally part of the old Ozark Trail, which was incorporated into Route 66 when the U.S. highway system was laid down. It remained part of Route 66, until the road was realigned in 1952. It still carries traffic as Historic Route 66.
