o A full access should be at least 845 feet from Armstrong Boulevard and a right <br /> in/right out access should be at least 470 feet from Armstrong Boulevard. <br /> • Bunker Lake Boulevard (west of commercial section): Expand to a four lane section for <br /> development (two westbound through lanes, one eastbound through lane and one <br /> center left turn lane). <br /> o Right turn lanes (locations and lengths) will be determined based on <br /> development type. <br /> o Outside westbound through lane drops to a right turn lane into the school <br /> property. <br /> • Puma Street: Expand to a three lane section for development (two through lanes and <br /> one center left turn lane). <br /> o Right turn lanes (locations and lengths) will be determined based on <br /> development type. <br /> • Bunker Lake Boulevard & Puma Street: An all-way stop, two-way stop, or roundabout <br /> will operate adequately at this intersection for the 2040 Full-Build conditions.The <br /> roundabout option may offer better operations than the other two options at 2040 <br /> Full-Build. <br /> Mid-Term Improvements <br /> • Armstrong Boulevard &Alpine Drive: Add northbound and southbound left turn lanes. <br /> Modify eastbound and westbound lanes to include a thru/left and a right turn lane. <br /> Another option at this location includes construction of a multi-lane roundabout with <br /> single lanes of approach on the eastbound, southbound, and westbound legs and two <br /> lanes of approach on the northbound leg. The completion of an Intersection Control <br /> Report(ICR) is recommended to determine the best intersection control at this <br /> intersection. <br /> • Alpine Drive & Puma Street: Add a westbound left turn lane and eastbound right turn <br /> lane. <br /> • Armstrong Boulevard & Bunker Lake Boulevard: Re-stripe southbound lanes to include <br /> a dual southbound left turn lane. A southbound double left turn lane will help reduce <br /> queues entering the COR development. Improvements were done in 2011 to this <br /> intersection and a future southbound left turn lane was designed, but not striped. <br /> Long-Term Improvements <br /> • Armstrong Boulevard & Bunker Lake Boulevard: Modify the southerly eastbound <br /> through lane to a through-right lane. Another option would be to keep the two through <br /> lanes and modify the right turn lane into a free right with an add lane that runs south <br /> to T.H. 10, or potentially add an additional right turn lane. <br /> Prepared by: Bolton & Menk, Inc.
