Specifications include, but are not limited to: The focus of this project is the reconstruction of the intersection of Addison Road and Walker Mill Road. The project spans from approximately 600 feet south of the intersection to around300 feet north and extends northeast to include the intersection of Walker Mill Road and Addison Road South. This project is the first phase of many future phases that will eventually reconstruct Addison Road from Walker Mill Road to MD 214, which will help enhance multi-modal transportation access to and from Addison Road-Seat Pleasant and Largo Town Center Metro stations. This is an area with a high pedestrian count due to the presence of many commercial properties. Therefore, there is an emphasis on traffic calming measures and pedestrian safety techniques in the design of this site. The proposed improvements consist of roadway widening, traffic signal upgrades, crosswalks/sidewalks installation, landscaping, street lighting enhancements, and environmental site design facilities. At the two intersections, the project will be providing traffic-controlled crossings. Where feasible, there will also be raised medians that offer pedestrian refuge as individuals traverse the intersection (see Figure 2). All existing traffic signals will be replaced with new equipment and all street lighting will be upgraded to enhance visibility. Where the sidewalk is adjacent to the curb, the sidewalk will be 6 feet to afford an additional measure of safety for the pedestrian. Other improvements will include a complete repaving of the roadway, new high-visibility signage, and the installation of drainage inlets and underdrains.
