Project Description

A single lane roundabout provides pedestrian crossings for all legs, improved and more predictable traffic flow through the intersection, adequate sight distance and clear delineation for vehicles and pedestrians. A short retaining wall may be needed on the northeast corner to minimize right of way impacts. Each adjacent property would maintain one point of access in and out of their driveway from SR 104 in both directions.

Existing Condition

The intersection of SR 104 and 40th Place NE/NE 184th Street is a skewed, four legged intersection with stop control for the southbound (40th Place NE) and westbound (NE 184th Street) approaches. The geometry of the intersection is problematic for many users, including misaligned legs that lead to confusion over which route is SR 104, as 40th Place NE can be viewed as the natural through movement. Lack of sight distance makes turning left onto SR 104 from both 40th Place NE and NE 184th Street hazardous creates unsafe pedestrian crossings. Conflicts between the two minor legs (40th Place NE and NE 184th Street) which are adjacent to each other confuses normal and legal ''yield to the right'' behaviors due to extreme delay on these legs during peak hour. Moreover, the intersection lacks amenities for those choosing to walk or bike. The intersection operates at LOS F today and will further degrade in the future. The corner between 40th Place NE and NE 184th Street is very wide with no pedestrian landing or marked crosswalk between the two approaches. The curb ramps on 40th Place NE are located 40 feet from the intersection, adding to the confusion of where to cross the stop controlled approaches. There is no pedestrian crossing of SR 104. Because of the sweeping curve of SR 104 combined with the odd cross-street geometry, there are accidents where motorists travelling too fast leave the roadway.'
