As a result, this plan will focus on roadside <br />safety improvements to reduce the severity and number of accidents on Kittitas County roads where it is most likely <br />that run-off the road crashes will occur. <br />From a safety perspective, the ideal roadway is straight with roadsides that are flat and unobstructed by hazards. <br />Straight roadways eliminate the need for drivers to navigate curves, reducing the chances of running off the road. <br />
