Project Narrative

(Summitview Road – FIN # 20020 - Forney Rd. to Hatton Rd.)





Roadway Widths:

Roadway currently maintains an average 20-21 foot paved roadway surface with right of way widths of 40-55 feet. Roadway will be reconstructed to a 40-foot roadway (12’ lanes / 8’ shoulders).



Vertical Curves:

Yakima County will address vertical alignment improvements as warranted.



Horizontal Curves:

Yakima County will address horizontal alignment improvements in the vicinity of M.P. 7.30 and 8.00.



Surfacing Type:

Summitview Road is primarily an asphalt surfaced roadway, except for a 1.4 mile segment (MP 5.09-6.49) surfaced with BST.



Structural Condition:

A CRAB inspection of the roadway resulted in a structural condition rating of 21. Roadway has significant longitudinal and lateral cracking. Limited shoulder scouring in some locations. Edge of pavement has significant disintegration in several locations requiring patching.



Capacity:

Traffic volumes (Yr 2007) along this route range from 4900 vehicles per day [v/d] at the Forney Rd. Intersection to 3200 v/d near the Tieton City Limits. Summitview Road, a two-lane Rural Major Collector (FC 07), is a Class 3 (T-3) Truck Route (300,000 – 4,000,000 tons), and a Class 1 Bicycle Route. Road is posted for 50 MPH.



Accidents / Safety:

This segment of Summitview Road has experienced 55 accidents since 2001, including a fatality in 2002. Most accidents (76.4%) are located in the southern end of the roadway segment (south of M.P. 7.65 – Funkhauser Rd Intersection). 38.2% of all accidents (21 of 55) occurred in or around the Summitview / Forney Road Intersection (a confluence of six roadways).

This road segment does not presently have appropriate shoulder widths to meet its Class 1 Bike Route designation. Complemented by Yakima County’s 2003-05 RAP award for Summitview Rd (between Appleway and Forney Rds.) this project will complete roadway and safety improvements along the entire Summitview Road Corridor between NW Yakima and Tieton.
