Avenue alternatives, the traffic flow is too imbalanced to proper roundabout operations. Based on these conclusions, the following is recommended: • Keep Line Avenue connected between Main Street/181St Avenue and Twin Lakes Road. The operations at the intersections are currently acceptable and no other compelling traffic reason exists for this change. • Change Line Avenue to place a cul-de-sac between the intersections of 5t" Street and Twin Lakes Road if other reasons beyond traffic operations suggest a change is needed. This change represents the least impact to travel patterns while maintaining satisfactory operations without any other m itigation. • Consider potential mitigation of a southbound left turn lane at the Twin Lakes Road/Line Avenue intersection, which will improve safety under existing conditions and under any alternative for Line Avenue. The proper median width already exists for this change and overall safety would increase, in addition to a slight operations improvement. • Consider potential mitigation of an eastbound right turn lane at the Twin Lakes Road/Line Avenue intersection, which will improve traffic operations if the Line Avenue corridor does not change or if the corridor has a cul-de-sac placed south of the 5t" Street intersection. • Revise the 5t" Street intersection with Dodge Avenue to recognize the dominant flow of traffic between the north leg and the east leg. This includes reconstruction to create a through movement between the two legs and allowing for through movements without stopping by repositioning the stop sign to the other leg. This is recommended under any alternative, including if Line Avenue is not changed. • Revise the 5t" Street intersection with Line Avenue to a roundabout if no alternative for Line Avenue is selected. Besides maintaining acceptable operations and recognizing the east -west flow, a roundabout would also slow traffic through this intersection. If Line Avenue is changed with a cul-de-sac placed south of the 5t" Street intersection, revise the 5t" Street intersection with Line Avenue to recognize the dominant flow of traffic between the west leg and north leg. This includes reconstruction to create a through movement between the two legs and allowing for through movements without stopping by repositioning the stop sign to the other leg. • Monitor the Twin Lakes Road/181St Avenue intersection for increased traffic volumes and decreasing operations. Future growth in the area along with changes to Line Avenue traffic are likely to warrant a traffic signal in the near future. Traffic Operations Study 13 Line Avenue in Elk River
