- Increased congestion and wait times may be experienced on WYO 390 due to the signal timing adjustments.
Adjustments to Optimize Traffic Flow on Teton Pass
The Wyoming Department of Transportation (WYDOT) has adjusted signal timing at the intersection of WYO 22 and WYO 390 in Jackson, Wyoming. These modifications aim to accommodate seasonal and daytime traffic flows. In particular, WYDOT engineers have shifted a portion of time from WYO 390 to WYO 22 to ensure a smoother flow of traffic off Teton Pass during specific times of the day. This measure is intended to prevent traffic from backing up onto the pass.

Addressing Capacity Challenges on Teton Pass
The summer season, coupled with construction, has led to congestion that exceeds the roadway’s capacity. This has, at times, resulted in gridlocked lanes. To alleviate this congestion on Teton Pass, WYDOT has implemented signal timing changes. They say they recognize safety risks of traffic stuck on the steep grades of the Pass. The goal is to address these challenges and create a smoother traffic flow.
Balancing Traffic Movement and Safety on Teton Pass
While the adjustments on WYO 22 aim to alleviate congestion, there may be increased congestion on WYO 390. WYDOT acknowledges the need to balance traffic movement through the signal while ensuring public safety. The decision to adjust the signal timing is a result of WYDOT’s effort to optimize traffic and promote safer driving..

WYDOT’s Goals for Teton Pass Adjustments
The signal timing adjustments implemented by WYDOT at the WYO 22 and WYO 390 intersection in Jackson, Wyoming, are aimed at improving traffic flow and safety, particularly on WYO 22 Teton Pass. While these changes may lead to increased congestion on WYO 390, they are essential for managing traffic volumes and preventing gridlock. Ongoing monitoring and fine-tuning of the signal timing will help strike a balance between traffic movement and public safety.
