Yakima County East-West Corridor Project
  

Corridors

  • Yakima County has identified four potential corridors for construction of the new East-West Corridor. These corridor alternatives are preliminary. The County will recommend a preferred corridor following public review and direction from the Yakima County Commission. Click on each map below to view a larger version. You may download and print copies of each map by going to the document library. Please let us know your opinion of each corridor by clicking the Thumbs Up or Thumbs Down buttons below each illustration. You may also open the project comment form to provide additional comments.

  • Corridor 1 "Ridge Top" (click image to enlarge)

    Corridor 1

    This corridor features a curved Yakima River Bridge that turns north sharply as it crosses the Yakima River and floodplain. The route intersects Marsh Road and immediately begins a steep rise up the Yakima Ridge. Once the roadway reaches the top of the first hill, it crosses the Roza Canal prior to the 11-mile Diversion of Wasteway #2 and skirts the tops of several hills before tying into the established eastern terminus for the East-West Corridor.

    This corridor affects the fewest homes and avoids both the US Bureau of Reclamation property and the Skyline Mobile Estates. However, this corridor will have considerably higher construction costs due to the large hillside cuts and fills—some of which are over 75 feet high—and extensive slope stabilization efforts required to correct the natural geologic instability of the Yakima Ridge.


  • Corridor 2 "Rest Haven Bench" (click image to enlarge)

    Corridor 2

    This corridor spans the Yakima River on a straight tangent, then moves east through the floodplain and north to intersect Marsh Road. The corridor skirts the western edge of the US Bureau of Reclamation property, rising steeply to the natural bench halfway up the ridge. East of this point, the corridor follows the existing Rest Haven Road footprint just beyond its intersection with Cut Off Road. As the roadway moves further east, the corridor begins a gentle rise up the Yakima Ridge and crosses the Roza Canal to tie in with the established eastern terminus for the East-West Corridor.


  • Corridor 3 "Ridge Base" (click image to enlarge)

    Corridor 3

    This corridor lies further south and sits lower in elevation at the base of the ridge. This corridor is complicated by the oblique angle of intersection with Marsh Road and the breadth of the US Bureau of Reclamation (USBR) property. Consequently, the County has explored a number of different options here, including the partial relocation of Marsh Road and/or a bridge over the USBR property. East of this area, the corridor traces the northern fringe of the Skyline Mobile Estates before rising sharply up the Yakima Ridge and crossing the Roza Canal to tie in with the established eastern terminus for the East-West Corridor.


  • Corridor 4 "Lowlands" (click image to enlarge)

    Corridor 4

    This corridor lies still further south, running parallel to the Columbia Basin Railroad tracks all the way to the existing intersection of Marsh Road and Butterfield Road. Between this intersection and the existing intersection of Keys Road and Butterfield Road, this corridor has a greater degree of interaction with the existing local roadway network than any of the other corridors. Consequently, the County has explored a number of different options to connect the new roadway to the existing streets, such as road relocations, grade separation viaducts, and/or intersection roundabouts. East of these intersections, the corridor swings north to begin an immediate rise up the Yakima Ridge and crosses the Roza Canal to tie in with the established eastern terminus for the East-West Corridor.
