Abstract

fetched live from OpenAlex

Highway 97 runs through the Okanagan region of British Columbia and crosses Okanagan Lake at Kelowna. By year 2000 an existing 3 lane floating bridge, opened in 1958, was in need of replacement due to severe traffic congestion and significant deterioration. Traffic volumes in excess of 50,000 vehicles/day were causing substantial delays crossing the only bridge across the 135 kilometre long lake. Delays were compounded by the requirement for the bridge to be temporarily closed to accommodate marine traffic. The Province of British Columbia examined alternatives to address the issues of a highway crossing Okanagan Lake and established project objectives to address safety, traffic capacity, tolling, marine traffic, pedestrians and cyclists. The project ruled out rehabilitation and then focused on a new crossing of the kilometre wide lake. After examining cable stayed and tunnel options a combined floating and elevated structure was selected as the preferred solution to meet all project objectives. The bridge was delivered as a Public Private Partnership DBFO project with SNC Lavalin selected as the Concessionaire in June 2005 with a design/construction cost of $(Cdn)144.5 Million. The 5 lane bridge was completed in May 2008, 3 months ahead of schedule and on budget.

Full frame distilled prediction

Teacher imitation

Not 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.
