F..E Warren Air Force Base in Cheyenne has indefinitely shut down Gate 2 at the intersection of Happy Jack Road. A recent traffic study indicates that, due to the resultant decrease in vehicle count, signalized lights are creating an unnecessary delay. On Monday, WYDOT will begin updating traffic control in that area to better serve the needs of motorists and cyclists.Signals at the intersection will flash yellow, thereby allowing a free flow of traffic on Happy Jack. Motorists approaching the intersection from the I-25 southbound off-ramp will encounter a flashing red signal indicating a requirement to stop and yield to all traffic on Happy Jack and then proceed. When weather permits the traffic signal heads will be bagged and stop signs installed for the off-ramp traffic control. Happy Jack Road will remain a free flow through the intersection.
