We've had a little trouble pinpointing on a map the actual crash site. One report denotes the crash happened on Hwy 90 just SW of the intersection of Old Spanish Trail and Hwy 90 (see red dot in first pic below). This would have meant their car had not yet passed over The Rigolets and the large steel bridge.
According to the Coroner's autopsy report (second pic below, courtesy of findadeath.com) the accident occurred about 1 mile west of The Rigolets (pronounces Rig-a-leez, French for "ditch") or the red "X" in the third photo below... but the coroner's report is not accurate. It is actually about 6 miles west of the Rigolets bridge. How does such an egregious error happen on an official report. The fourth photo below marks the actual crash site on a map.
If any of you Mansfield experts out there have any knowledge of the exact whereabouts the crash took place, we'd greatly appreciate it if you'd let us know.
The below photograph has been updated with what we believe to be the exact location of Jayne Mansfield's crash site. See the video elsewhere in this thread that shows the Jayne Mansfield roadside memorial erected by a fan:
