Due to the high degree of maintenance needed by the rubberized speed cushions on SW Dawson near 18th Ave SW, the Seattle Department of Transportation (SDOT) will reconstruct these speed cushions in asphalt. The speed cushions were constructed with three other sets some time ago through a Neighborhood Street Fund grant. The community had documented relatively high speeds; 15% of the vehicles were traveling over 35 mph. Speeds slowed significantly as a result of this project.
SDOT will remove the rubber speed cushions on SW Dawson and cover the warning signs. The speed cushions will then be rebuilt in asphalt and the signs uncovered. The rubber speed cushions may be removed as early as this week. As asphalt is somewhat weather dependent, there may be some lag before the cushions are rebuilt.
