Kittitas County Transportation Element 2018 <br />Table 1. Classifications of Roadway <br />Roadway Description/ Purpose Example Photo <br />Type <br />Interstate <br />Principal <br />Arterial <br />Minor <br />Arterial <br />Major <br />Collectors <br />Minor <br />Collectors <br />Local <br />Streets <br />Interstates primarily serve long distance travel <br />between cities and carry high volumes. They <br />provide only limited access via grade separation <br />and access ramps. <br />Principal arterials tend to carry the highest <br />volumes of any roadway type below interstate <br />routes . They can potentially serve regional <br />through trips and connect the region . <br />Minor arterials are designed for higher volumes, <br />but tend not to be major regional travel ways. <br />Minor arterial streets provide inter-neighborhood <br />connections. <br />Collectors distribute trips between local streets <br />and arterials and serve as transition roadways to <br />or from commercial and residential areas . <br />Collectors have lower volumes than arterials, and <br />must balance experience for all modes. <br />Minor Collectors serve a similar purpose to Major <br />Collectors, however they are distinguished by <br />having lower traffic volumes and more <br />connecting driveways . Minor collectors offer <br />more access at lower speed and with fewer travel <br />lanes. <br />Local streets are the lowest functional <br />classification, providing circulation and access <br />within residential neighborhoods. Many local <br />streets do not require sidewalks given their lower <br />traffic volumes and speeds. <br />Source: Fehr & Peers, 201 8 <br />1-90 <br />1-82 <br />University <br />Way <br />US97 <br />Vantage <br />Highway <br />Kittitas <br />Highway <br />Thorp <br />Highways <br />Number 81 <br />Road <br />Hungry <br />Junction Rd <br />Mohar Rd <br />Denmark <br />Road <br />Ferguson <br />Road <br />19 IP age
