Improvements to SR 99
With the goals of increasing safety, improving pedestrian accommodation, and creating a more attractive corridor, the cities’ redevelopment plans included several specific proposed improvements to SR 99:
- Replacing the center TWLTLs
with a raised median to accommodate tree plantings and other landscaping,
provide a refuge for pedestrians, and improve access control (Figure 100).
would be restricted to major intersections, and some U–turn areas would
be provided at selected locations (Figure 101).
- Providing additional improvements
for pedestrians, such as pedestrian lighting, improved crossing points,
and improved transit stop areas (Figure 102 and 103).
- Adding HOV or bus transit
lanes on each side, as well as tree plantings, sidewalks, and lighting
(Exhibits 7.7 and 7.8), through use of the wide paved shoulders as well
as some additional right-of-way acquisition.
- Consolidating and defining
driveways and other access points (Figure 103).
- Placing utilities underground
- Aesthetic enhancements (Figure
Drawing of proposed improvements to SR 99 in Shoreline.
Figure 100 is an artist’s rendering of proposed improvements to SR 99 at an intersection in Shoreline. The rendering shows a road with two lanes in each direction and a raised, landscaped median; brick–paved pedestrian crosswalks and dedicated left–turn lanes at the intersection; overhead traffic signals; blue decorative streetlights; wide sidewalks; and a dedicated bus transit lane.
Left-turn lane and U-turn areas after reconstruction in Federal Way. A much greater level of access control was achieved.
Figure 101 consists of two photos of left-turn and U-turn areas along SR 99 in the community of Federal Way. In both photos, these areas are between the travel lanes and a landscaped median. Vertical rectangular signs mounted in the median contain the words LEFT & U TURN AHEAD in advance of the turning area. The signs are white with black borders and lettering.
New transit stop in Des Moines
Figure 102 is a photo showing a new transit (bus) stop on SR 99 in the community of Des Moines. The facility’s amenities include a bus shelter with etched glass sides, pedestrian and street lighting that has been painted to match the shelter structure color, special curb markings, landscaped areas, and a wide paved sidewalk. The lane adjacent to the transit stop has a diamond painted on it.
