20 kept routes from 20 solves. Graph 28,772 nodes, 42,215 edges (OSM drive network, pad 12.0 mi, toll and motorway kept). Dollars = calculator multiples of $12.00/ft dirt bore, soils sampled every 50 ft from CONUS_soilbid9_10m. Not-bore rule in use: place_and_soil (trench outside 26 incorporated places, soil class 7 or lower, motorway bore only; pavement percent is step 3). Diversity: named carriers AT&T, COGENT, FIBERLIGHT, LUMEN, MOX, SEGRA, UNITI, ZAYO from GeoTel; shared = within 250 ft, near = 250 to 1000 ft. Metro, permitting mapping and water detection are step 3 and 4 placeholders. Dashed black line = human route, comparison only.
Cost versus diversity
One dot per kept route: x = dollars, y = diversity (share of the route farther than 250 ft from every named carrier line). Hover a dot to see the route; click to select it on the map and in the table. The hollow marker is the human route, comparison only.

blend = 0.00
score = (1 - blend) x (dollars / min dollars) + blend x (miles / min miles). Lower is better. Click a header to sort; click a row, a line or a dot to highlight.

Assumptions in use
Every rate is base x multiple. Changed values (overrides) are shaded. Rows marked placeholder are step 3 or 4 work.
