Charlie's correct in this.
If there is no legitimate reason to "Build" an arch, the standard construction company would build the road on a fill dirt hill.
Then place a retaining wall across the front of the dirt or use the first arch support/wall as the retainer, Then begin the viaduct from there.
The picture on this page shows the PRR/Reading viaduct near me. It starts right at the hill in the background.
