County reports progress on overlays, sidewalks and a cracked bridge panel needing DOT review
Summary
Public works staff updated supervisors on multiple road projects — Z34 overlay completion, Monmouth Division Street concrete work, Preston Highway improvements and a cracked bridge panel that may require full-panel replacement or DOT-directed remedy.
County public-works staff on May 20 updated the Jackson County Board of Supervisors on the status of several road and sidewalk projects and noted one bridge panel had cracked and may require a full replacement under DOT inspection.
The Z34 overlay asphalt work is complete and crews are awaiting milling of rumble strips and final pavement markings, the presenter said. Monmouth Division Street concrete work is finished and River City is expected to mobilize after Memorial Day for its portion of the project. "The asphalt will be done from curb to curb," staff said of the Monmouth project.
On Preston Highway and the Main and Summit projects, retaining walls and sidewalks remain in progress and rain is causing short delays; staff estimated completion in a few weeks for those segments. Staff noted pavement markings under a Highway Safety Improvement Program (HSIP) grant will include 6-inch lines rather than 4-inch lines.
Bridge issue: staff reported that one concrete approach panel on a bridge had cracked on the south side and that the Iowa Department of Transportation (DOT) will likely note it during its walk-through. Staff said they are evaluating whether a patch under DOT standards would be acceptable or whether a full 11-by-20-foot panel replacement will be required. "If a patch is acceptable, it's kind of a route I'm leaning," the presenter said, but replacing a full panel would be costlier and could require closing a lane for repairs.
Channelworth/Moorhead update: staff said preliminary plans for a Channelworth project were submitted last week and the DOT decision on a Moorhead funding opportunity is still pending; staff said DOT had not yet informed the county and that a decision had been expected by March and slipped into May. "I do not have an answer on that grama status as the DOT has not yet informed me," staff said.
Next steps: staff will coordinate with DOT about the bridge panel repair standard (patch versus full-panel replacement), finalize milling and pavement marking schedules, and continue follow-up on the Moorhead funding decision.
