Uneven road with unstable subsurface

Am writing to formally raise a serious concern regarding the condition of the road, particularly on the southbound lanes, but also affecting the northbound lanes to some extent. The road exhibits severe undulations that are highly alarming, especially given the posted speed limit of 50 miles per hour. These conditions pose a significant safety hazard to all road users. As previously highlighted by other concerned individuals, the undulations cause heavy vehicles carrying loads, as well as smaller vehicles, to be tossed around unpredictably. This creates a dangerous driving environment, and it seems inevitable that a serious accident will occur if this issue is not addressed promptly. Furthermore, the road surface itself appears to have been compromised over time. The unevenness seems to have worsened, likely due to factors such as precipitation or subsurface erosion. It is apparent that the most severe areas of unevenness could be tracked and mapped over the past 15 months, indicating a progressive deterioration of the roadway. Failure to address this matter can only be interpreted as negligence toward the safety of road users. I urge you to take immediate action to investigate and rectify these hazardous conditions before they result in preventable accidents or injuries
