County engineer updates supervisors on roadwork, bridge testing and shared equipment plans
Summary
Winneshiek County’s county engineer reported routine maintenance items, said Iowa State conducted strain‑gauge testing on flat‑car railroad bridges, and described potential shared use or rental of a mastic machine and a new scrub‑seal option under evaluation.
County engineering staff provided the board with regular operations updates covering maintenance, equipment trials and several bridge projects.
Staff said there were no new grants this week and that Iowa State University completed testing on additional railroad flat‑car bridge span lengths and installed strain gauges; results were expected back in December and will inform whether posting or weight limits will be needed. The engineer’s office said DENCO visited to showcase a new machine that might allow a scrub seal on sections of High Point East (Allen Drive); staff will evaluate feasibility given existing surface conditions.
The county discussed possible shared acquisition or rental of a mastic machine with the city street department to seal concrete joints and address potholes and that contractors (Brunings are referenced) are lined up to pave certain stretches, with patching and culvert work continuing this week. Staff reported Bridge 126 clearance work completed with letting likely in January and said Frankville Road letting will be after 2026. Striping on another county route occurred Monday, and durapatchers are operating from the shop this week.
On emergency equipment, staff described a new 6‑inch pumping apparatus acquired through a grant for flood response that might be available through interagency sharing; staff encouraged other supervisors to follow up with the city street department contact.
Board members questioned specifications for new subdivision roads and reiterated the county’s general policy not to accept new subdivision roads into the county system unless previously grandfathered or built to county standards.
