The Wyoming Department of Transportation has announced that a roundabout is the preferred alternative to improve safety and operations at the intersection of WY 332, WY 335, and U.S. 87, commonly known as the Big Horn Y intersection. The decision follows an extensive traffic study and significant public input.
WYDOT contracted with HDR to complete the Big Horn Y Intersection Study to address the public’s growing concerns regarding safety and efficiency at the busy junction. Data collection and feedback from the public revealed issues including near-miss crashes, drivers failing to yield, speeding, traffic congestion during peak hours, long wait times, and difficulties for pedestrians and cyclists. WYDOT District Traffic Engineer for NE Wyoming District 4 Michelle Edwards said that HDR followed a strict set of criteria for the study.
Based on detailed analysis and public feedback gathered through two online and one in-person meeting, the results determined that a roundabout and an all-way stop were the best alternatives to carry forward for in-depth analysis. Ultimately, the roundabout emerged as the preferred alternative due to its significant safety benefits and public support.
While a roundabout is the preferred solution for the long term, it is not currently funded in the six-year State Transportation Improvement Program (STIP). WYDOT is considering a short-term solution of either reducing the posted speed limit at the intersection or eliminating the free right of U.S. 87, as per the recommendations in the study.
