Evaluation factors to develop improvement options

WSDOT considers many factors to evaluate on all projects, including SR 900. Some of these include:

An image showing an example of a three-lane road, one in each direction and a two-way center left-turn lane. There is an overhead pedestrian hybrid beacon with solid red lights activated. A pedestrian is crossing the roadway, using the crosswalk and a vehicle is stopped at a stop line.
Figure 4: Example of a Pedestrian Hybrid Beacon (a protected crossing). All red (shown) allows pedestrians and bicyclists to cross while vehicles are stopped.
An image showing two lanes of westbound SR 900, west of 133rd Street South, next to a steep hill. There is grass vegetation, trees, and exposed dirt on the steep hill. There is a narrow shoulder between the travel lanes and the steep hill with small accumulations of dirt on the shoulder.

An image showing an example of a wide shared-use-path that is protected with a small (4 to 6 feet high) retaining wall that is built into a hill. A patterned concrete buffer separates the shared-use-path and travel lanes until the crosswalk. On the near side of the image, a vegetated buffer separates the shared-use-path and travel lanes.
