Abstract
As the popularity of the then St. Paul, Minneapolis, and Manitoba Railway (later, the Great Northern Railway Company) began to grow in the late 1870s, the need for a rail bridge in Minneapolis over the Mississippi River became more prominent. This article provides an overview of the construction of that historic bridge, which came to be known as the Stone Arch Bridge. The structure was designed to cross the river at a diagonal with a 6-degree curve that changed the alignment from due west to northwest. The viaduct's 23 arch spans were comprised of 100,000 tons of limestone and granite, some of which came from quarries as far away as Wisconsin and Iowa. The stone was hand laid, and the cement mortar was mixed with salt and hot water to keep it from freezing in the cold weather. Construction of the 2,100-ft-long bridge and the 2 sets of tracks it carried over the Mississippi concluded in November 1883 at a total cost of approximately $700,000.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
