Old US 75 Dragoon Creek Bridge

The bridge over Dragoon Creek in Osage County is on “S Old 75 Hwy” which is still somewhat paved (E 205th St is a graveled road to the north). It was used by local traffic until the end of 2009 when KDOT installed the current concrete barricades. It is scheduled to be demolished w/ in the next two years.

Cool one....easy access on south side. Built 1954, abandoned when?....just like the 93rd St. bridge in Auburn and the old HWY 54 bridge in Reece and many other not-so-old concrete monsters that are bypassed relatively early, still....this one worth a visit

When girders are "arched" like this, they're not actually acting as an arch where all members are in compression. This is simply a thickening of the girder where the shear is highest near the supports. It looks nicer than a straight girder, but is more expensive to cast.

This bridge is neither a stringer nor a slab--there is one spot in the street view where the reflection of the bridge's underside can be clearly seen, revealing that the bridge is a concrete girder bridge. It has only the outer beams, with perpendicular floor beams connecting them. Somewhat like a stringer, but definitely not a slab.

While NBI lists this bridge as a concrete stringer, a quick look at google earth ground view from the current US75 bridge tells me this is an arched concrete slab, so I listed it as such.
