“Eighth Wonder of the World:” The Cariboo Wagon Road as British Columbia’s First Megaproject
Bibliographic record
Abstract
Interpretations of the creation and operation of the Cariboo Wagon Road, constructed during the 1860s to the gold fields in the northern interior of colonial British Columbia, range from a marvelous, essential conduit to a costly, superfluous thoroughfare. In our age of cost overruns, it is appropriate to begin a process of addressing cost-effectiveness in evaluating the colony’s largest infrastructure project. After clarifying the structure’s name and extent, this paper collates the relevant British Columbia colonial accounts to establish a global government first cost of the project and compares this expenditure with the cost of goldfield roads in California and Victoria colony, Australia. It then engages with the theory and practice of megaproject analysis in two ways. First, if offers a brief comparison of select primary sources concerning the Cariboo Wagon Road with some of the very different documents that support studies of major projects in the post-war period. It then deploys elements from the growing planning literature concerning megaprojects that allow analysis within the very constraints of the colonial sources. Such an endeavour illuminates some of the shortcomings and gaps in nineteenth-century calculations and understandings of the financial viability of the project.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
