The Pasco-Kahlotus Road serves as a vital 42-mile arterial, connecting the eastern section of Franklin County. Since the late 1800s, this road plays a critical role for the county’s residents, facilitating the movement of freight and agricultural goods, providing access to two dams, and connecting to multiple recreation areas along the Snake River and Juniper Dunes Recreation Area.
This T3 classified road plays a pivotal role in transporting a diverse range of agricultural goods from farms to markets. In 2003, Franklin County initiated multiple phases to upgrade the Pasco-Kahlotus Road, focusing on overlay and widening. The goal was to enhance the roadway to meet current design standards and ensure it functions as an all-weather route.

The County upgraded the roadway to an all-weather route from SR-12 to MP 13.08 (Herman Road). However, the last phase of a 3.01-mile section, spanning from MP 5.92 (Peterson Road) to MP 8.93 (Ice Harbor Road), remained unfinished due to the complexity and cost of the project.

The Pasco-Kahlotus Road Reconstruction and Overlay II project, also known as CRP 605, focuses on a 3.01-mile segment of the Pasco-Kahlotus Road. This particular section faces several challenges, including deficient sight distances due to vertical curves, steep slopes, and a narrow roadway. Additionally, weight restrictions applied at various points during the year, which is problematic, as this road serves as the sole north/south route for eastern Franklin County.

The Pasco-Kahlotus Road project addressed the reconstruction of substandard vertical curves at four different locations, widened the roadway from 26' to 34', milled and preleveled the sections of roadway that did not need reconstructed, and paved the entire section adding structural strength and bringing this last section of roadway to an all-weather route. Additional upgrades to the road were left/right hand turn lanes into the Juniper Dunes Road, illumination at the intersection, installation of both culverts and shoulder rumble strip.
These improvements enhanced the safety,
