Project Description

'The proposed solution to the problem at this intersection would be to design and construct intersection improvements that will allow for the safe movement of vehicles, bicycles, and pedestrians while also accommodating transit stops. The only solution that meets all of these goals is the installation of a roundabout. The City evaluated installing a 4-way stop controlled intersection but the control would cause east bound traffic to back-up into SR-9.Arlington evaluated options for this intersection with a traffic consultant, a copy of the planning level roundabout design is included with this grant application (Att #2). With this design, vehicles will be slowed by the roundabout configuration and allow for the safe movement from all four legs of the intersection. Pedestrian facilities will be on all four corners and connect to existing sidewalks. Crosswalks will be installed on all intersection legs and include safe refuge islands at all crosswalk midpoints. The intersection improvement will expand the existing NW and SE corner bus stops.This grant request is to fund the design, ROW procurement, and construction of a roundabout at the 204th St and 77th Ave intersection. The community is in full support of a safer intersection
