NE Manley Road (Road Log #95550) is a high-volume Rural Minor Collector, running north-south near the City of Battle Ground with an ADT of 2184.
Large quantities of rocks and debris filled the undersized culverts and water was ponding upstream. Roadway embankment erosion was occurring from water seepage through the soil, which is possible evidence that water was piping around the culvert due to the lack of culverts headwalls. Manley Road had a VCI of 70 and pavement distresses include sags/humps, raveling/aging, and flushing. The consequences of not addressing pavement condition and failing culverts would have been on-going deterioration, higher costs in the future to address, adverse impacts to commerce and safety of the traveling public.
The construction project included a structural asphalt overlay with safety edge to improve horizontal curves, safety and maneuverability. Existing utility poles and roadside objects have been relocated, delineated, or protected where feasible. Roadway striping and updated pavement markings have been applied where needed. Substandard guardrail has been replaced or upgraded, including end treatments, height and post configuration. Further improvements included replacing the current CMP and concrete culverts with three new structures spanning the creek, placing riprap, and grade control structures in the channel. Two new 12” roadway drainage culverts have also been installed. Improvements meet hydrologic and permitting requirements; allow aquatic life and fluvial debris to pass; and accommodate 100-year flood flows.
