Okay, so it has been a while since I have written a bridge story on here. I try to restrain myself from writing about too many bridges, but I did cross a very interesting one recently. While driving across Texas, I drove over the Roy Inks Bridge in Llano, Texas.
By the 1920s, many states were coming up with their own designs for Highway truss bridges. Texas was no exception. As a result, many of the truss bridges built in Texas during the 1920s and 1930s have a standardized look to them because they followed a standardized design. Neighboring states such as Oklahoma, had their own State Standard Designs which differed from those in Texas. In earlier decades such as the 1880s and 1890s, most truss bridges were designed by companies instead of jurisdictions. State standardized designs did not become a common phenomenon until the latter half to perhaps the latter quarter of the truss era.
By about 1940, concrete bridges had largely superseded truss bridges. The Roy Inks Bridge was built in 1936, right at the twilight of the truss bridge era.The bridge is a very popular local landmark and has been the subject of many photographers. It is a great bridge and worth a visit if you are in the area. It is a 4 span Parker Truss bridge.
