Tama County’s Sept. 22 meeting packet includes Resolution 9-22-2025A, which would establish a temporary 35 mph speed limit on 190th Street from X Avenue west to V18 while Iowa Highway 8 is closed, and would terminate when the highway reopens. The resolution text cites Iowa Code sections 321.255 and 321.285 as the board’s authority to set reasonable speed limits on secondary roads.

The resolution states the change is needed because “the current closure of Hwy 8 from V18 to V Avenue has caused increased traffic on 190th St. west of Dysart,” and requires that “appropriate signs shall be erected at the locations described.” The packet shows the proposed limit as “35 mph on 190th Street commencing at X Ave and proceeding west to V18.”

The meeting minutes included in the packet do not record a separate board vote for this Sept. 22 resolution; the Sept. 15 minutes in the packet record prior speed‑limit work (a different resolution setting 35 mph on K Avenue during a closure) and engineer updates. County Engineer Ben Daleske is identified elsewhere in the packet as the engineer responsible for road projects and for bringing speed‑limit recommendations to the board.

Status and next steps: The record supplied with the meeting packet shows the resolution text available to the board at the Sept. 22 meeting; the minutes in the packet do not contain a recorded outcome for Resolution 9-22-2025A. If adopted, the resolution states signs will be placed and the limit will end when the referenced section of Hwy 8 reopens.

Authority: The resolution text cites Iowa Code §§ 321.255 and 321.285 as the statutory basis for establishing speed limits on county secondary roads.
