Peak Hour <br />• Limited gaps in free-flow southbound Lexington Avenue traffic, in combination with <br />northbound U-turn maneuvers, result in significant delays on the eastbound South Access <br />intersection approach (LOS F), which impacts approximately 25 p.m. peak hour vehicles. <br />Recommended Short-Term Improvements <br />To provide the study area and proposed expansion with acceptable levels of service/queuing and safe <br />operations in the short-term, the following geometric/traffic control improvements are recommended <br />for consideration. <br />Study Intersections <br />County Road F/Hamline Avenue Intersection <br />• Extend the westbound right-turn lane to accommodate 150 feet of additional vehicle storage. <br />County Road F/Innovation Way Intersection <br />• Implement traffic signal control. <br />o Construct the northbound/southbound approaches with a shared through/left-turn lane <br />and a dedicated right-turn lane. <br />o Construct the eastbound/westbound approaches with a dedicated left-turn lane and a <br />shared through/right-turn lane. <br />County Road F/East Access Intersection <br />• Implement three-quarter access to maintain inbound heavy truck access. <br />County Road F/Lexington Avenue Intersection <br />• Reassign the three eastbound approach lanes as dedicated left-turn/through/right-turn lanes. <br />Implement an eastbound right-turn overlap with the northbound left-turn signal phasing. <br />Lexington Avenue/South Access Intersection <br />• Construct a three-quarter access intersection to prohibit eastbound left-turn maneuvers. This <br />intersection layout would be expected to function well with the planned three-quarter access <br />intersection at Lexington Avenue/Gramsie Road. <br />An illustration of recommended short-term improvements is shown in Figure 6.
