Roadside Inventory Map
Every field-mapped roadside element, barrier, sign, pole, rock face, and treeline, positioned on the design centerline by station and side. The pure inventory, with no crash overlays.

05
Roadside Inventory & Crashes
The field-verified roadside inventory and the crash history on one map: barriers, signs, poles, rock face, and treeline, with each crash tied to the object it struck, plus where a barrier would have helped.
Live
06
Priority Segments & Curves
Barrier-candidate priority segments against the horizontal alignment: curve or tangent, EPDO, pavement condition, and a treatment lean, plus curves with recurring dry-pavement crashes and existing barrier coverage.

Abandoned Mines
USGS prospect- and mine-related features, quarries, gravel and sand pits, and mines, digitized from historical topographic maps across Dane and Iowa County. Filter by type or county; each feature links to its USGS record.
