Consideration of a resolution to change the speed limit for two segments of Rd 215, Iron Mountain Rd, from mile post 0.0 to 2.00 and mile post 2.00 to 5.0. (Postponed from Feb 3, 2026)

Summary

Laramie County is considering a resolution to increase the speed limit on two segments of County Road 215, Iron Mountain Road. A speed study conducted in June 2024 by Inberg-Miller Engineers analyzed the paved sections from mile post 0.0 to 2.00 and mile post 2.00 to 5.00. The study found that the 85th percentile speed in both sections was 59 mph, with an average daily traffic of 1,029 vehicles (MP 2.0-5.0) and 1,186 vehicles (MP 0.0-2.0). Based on these findings and Wyoming Statute 31-5-303, the study recommends increasing the speed limit from the current 45 mph to 55 mph for both segments. The resolution, if adopted, will authorize the County Public Works Department to post the new speed limit signs.

Citizen Impact

Residents using Iron Mountain Road (CR 215) may experience faster travel times as the speed limit is proposed to increase from 45 mph to 55 mph on sections between mile post 0.0 and 5.0. This change is based on engineering studies indicating current traffic speeds align with the higher limit.
