Improvements to the roadway and traffic signal are required at this intersection in order to accommodate a left turn yield on green instead of a red arrow. The necessary improvements are scheduled to be completed in 2015. After the improvements are completed, a red arrow will still be needed during rush hour periods because traffic volumes are too high to allow for left turn yield on green operation. The left turn yield on green may be possible during periods of lighter traffic (i.e. evening/overnight).

In the meantime, the amount of green time for the southbound Hwy 55 to eastbound Lone Oak Rd is limited due to the traffic signal coordination on Hwy 55. In order to give more green time to the southbound Hwy 55 to eastbound Lone Oak Rd left turn, green time would need to take away from another movement at this signal which may be difficult depending on the time-of-day. There are 6 different timing plans at this signal, so it is important to know the specific time-of-day that the problem is occurring so the signal operation can be monitored in the field and an adjustment made, if possible. Can you please provide a specific time of day for your observations?
