In 1970, the "Red Mountain Expressway" was completed after many years of work cutting through Red Mountain.
 This highway linked Birmingham with its southern suburbs and spurred suburban growth towards the south of Birmingham.
The resultant cut exposed geological strata spanning millions of years, including the red ore seam that spurred Birmingham's development.
A new species of Lower Silurian (middle Llandovery) phacopsid trilobite, Acaste birminghamensis, was first collected from exposures on Red Mountain
