Work to add safety features on several rural Franklin County roads could start within the next month.
The county public works office plans to start preliminary engineering and surveying soon.
Franklin County has received a $750,000 federal grant for the County Road Safety Program, with $500,000 for projects that could help prevent run-off-road crashes and $250,000 to improve intersection safety.
Guy Walters, county assistant public works director, said the earliest construction would begin on any of the projects would be this summer.
Intersection improvements, the first phase of the project, will include improving sight distance at intersections in west Pasco by such changes as removing vegetation that blocks motorists' views, Walters said. That work is planned on Argent Road at both Roads 60 and 72 and on Court Street at Road 52.
Walters said the county also will add flashing lights at intersections, audible rumble strips and oversized signs, delineators and warning signs on intersections along Road 170 west of Basin City.
Other work on the list includes installing flashing lights and rumble strips on Glade North Road intersections with Elm, Ironwood and Russell roads, on Taylor Flats Road at intersections with Alder, Birch and Fir, and on Langford Road at the Sheffield and Russell road intersections.
Water hazards will be removed along Columbia River Road during phase two. Walters said the work includes flattening slopes, adding guardrails and extending irrigation culverts. There is a deep ditch alongside the road that Walters said they might replace with a pipe, and then fill the ditch to prevent vehicles from running of the road into it.
Sheffield Road and Langford Road also are listed to have slopes flattened and culverts extended in the second phase.
Phase three of the work will include flattening slopes, installing culverts and adding guardrails on Wahluke Road and Ringold Road, Walters said.
Walters said the county has enough money to finish each phase, but not enough for all the projects.
"The list is longer than the funding," he told commissioners Wednesday.
The commissioners amended the county's 2011-16 Transportation Improvement Plan on Wednesday to allow the county to use the $750,000 grant on the road safety projects.
