Secondary roads updates: paving and bridge work proceed while board weighs additional safety measures at 150th & Noble
Summary
County secondary roads staff reported progress on asphalt and bridge projects, rumble‑strip work and HMA patching, and discussed complaints about motorists missing the stop at 150th & Noble; staff described existing controls, MUTCD standards and the costs and limitations of LED/flashing devices.
Carroll County secondary roads staff updated the Board of Supervisors on ongoing paving and bridge projects and discussed safety options for an intersection at 150th & Noble after multiple complaints that motorists fail to stop.
Zach, a secondary roads staff member, said HMA asphalt work on Dedham and Manning is complete from an asphalt standpoint, but pavement markings and rumble strips remain to be installed. He said crews are moving on other projects — including an intermediate layer on Lauderdale Road — and that bridge abutments were formed and poured, and piles had been driven on another bridge project.
Zach described recent rumble‑strip work countywide: crews cut 15 new panels at several intersection legs and recut about 30 panels elsewhere to restore full depth and improve audibility. "We went and evaluated all throughout the county," he said, and described HMA patching operations that paused for rain.
Supervisors raised a continuing complaint at 150th & Noble (also referred to in the meeting as near North Maple River and Ivy). The board and staff noted the intersection has a stop sign, a stop‑ahead sign and rumble strips; residents reported vehicles still running the stop during daytime hours. Board members and staff discussed possible additional countermeasures including LED stop signs and flashing‑light fixtures.
According to staff, LED stop signs cost "just north of $4,000," and an LED flashing light unit is "a little less" — staff said he was "thinking more like $1,700–$1,800" for the flashing light (comments recorded on the meeting transcript). Staff also warned of maintenance and longevity concerns: some LED units have failed after a few years and replacement inventory can be limited.
Board members discussed other constraints: the Manual on Uniform Traffic Control Devices (MUTCD) sets standards for sign placement and that creating a stop condition by adding a stop sign on the through (East‑West) route could conflict with those standards. Staff said sight distance at the intersection is adequate and that physical countermeasures — rumble strips, signs and potential solar LED devices — are among the remaining options.
Supervisors asked staff to continue monitoring and, where warranted, to deploy available devices; staff said one flashing unit remained in county stock and could be installed to test effectiveness. The board did not take a separate formal vote on installing LED or flashing devices during the meeting.
Other operational notes: crews recovered milled shoulder material at Manning, addressed driveway and intersection repairs, applied dust control near projects, and continue to schedule pavement markings once multiple projects are complete. Staff encouraged reporting of specific problem locations so crews can evaluate whether further engineering or pavement adjustments are required.
