Adams County highway staff told commissioners Tuesday that major construction is underway on several road and bridge projects including two large box culverts, a guardrail repair job and a precast bridge scheduled for shipment in August.

The most advanced work is a replacement of two undersized or undermined culverts, one described as nine sections of a 53,000‑pound precast box per section. Highway Superintendent Nate said crews set the heavy sections and crews will complete pavement restoration and final touches, including gabion baskets and asphalt, pending supplier schedules.

Bridge 180, which spans the intersection of 650 West and 825 South, is scheduled for precast shipment in August and should take five to seven weeks of work on site, Nate said. Because the bridge sits at a crossroads, the project will require a full intersection closure during installation and subsequent restoration work.

Nate also updated the board on a guardrail safety grant. The state Department of Transportation had issued a pre-proposal document for construction inspection; consultant proposals are due Sept. 4. Separate guardrail damage from bank erosion and a crash will require short lane closures as contractors replace in-kind rail and repair bank damage.

Other updates: County Road 700 South concrete work is underway; crews hope to have the road open by the start of school in early August. Chip sealing is down to roughly 20 miles remaining; chip/seal support equipment has intermittent availability as the county’s sweeper and chipper were reported down and weather slowed work.

Why it matters: The culvert and bridge replacements address undermining and load‑posting problems that had reduced structural capacity and increased public-safety risk. Officials said the larger precast structures are intended to provide 65–75 years of service life and added channel capacity for future ditch maintenance.

Traffic impacts: Drivers should expect one‑lane work zones on guardrail repair sites and a full closure at the Bridge 180 intersection during the precast installation. County staff said they will coordinate notifications for closures and suggested using an app or other county communication tools to better inform residents about road work.

No formal votes were required for the updates; staff will continue coordinating contractor schedules and public notices.
