Des Moines County officials weigh responses after state raises many paved-road limits to 60 mph
Summary
County engineers and supervisors described logistical, safety and signage challenges after a recent state action raising many paved-road speed limits to 60 mph effective July 1. Staff proposed temporary county resolutions, targeted engineering reviews of curves and phased sign changes.
County officials spent a lengthy portion of their meeting debating how Des Moines County should respond after a recent state action raised many paved-road speed limits to 60 miles per hour, effective July 1.
Ryan Carter, a Secondary Roads representative, told the board the increase presents immediate logistical problems for counties: sign inventories are limited, engineering studies are required to lower limits in specific locations, and some existing curves lack designs appropriate for 60 mph. "One possible option is coming to the board and doing at least a short-term countywide resolution to leave everything at 55," Carter said, adding that sticker conversions and phased reviews could be used while departments complete more detailed engineering work.
Sheriff Kevin Glend and other supervisors joined the discussion, noting liability and enforcement concerns if curves or intersections do not meet higher-speed design standards. Carter said counties may need to sign more boundary signs and that some jurisdictions may choose to keep 55 mph in practice until signage and engineering reviews are complete. He estimated that sticker production and distribution will take time because demand from across the state is sudden.
Carter urged a cautious approach that balances safe design with the state law change. "There's a lot more behind the scenes than people realize to the signing on highways," he said, describing both the short-term challenges of procuring signage and the longer-term need to review curves and intersections.
Why this matters: the board is the local authority for posting and enforcing many county speed limits; changes can affect enforcement, signage budgets and county liability for roads that do not meet design standards for a higher posted speed.
Next steps: supervisors said they will gather further information, consider a short-term resolution to maintain 55 mph where appropriate and schedule countywide and statewide engineer conversations to coordinate signage and safety reviews.
