The Connecticut Department of Transportation (CTDOT) is conducting a roadside herbicide spraying program from May 22 through August 31, 2023 along Interstates 84, 91, 95, 384, 395, 691 and all other divided highways and secondary roads in accordance with the CTDOT Vegetation Management Guidelines.
CTDOT uses herbicides to safely and effectively control the encroachment of vegetation along and under guiderails, signs, and barriers within the state-owned right of way. Guiderail and barrier systems along divided highways and ramps will be treated beginning in the southern region of the state, followed by the central region, the western region, and lastly the eastern region.
The guiderail and other barrier systems along secondary state roads will be treated beginning in the central region, eastern region, southern region, and lastly the western region. From August through November 2023, a program of spot spraying will be in place to manage specific locations populated by invasive plants and trees.
Travel impacts will be minimal as this operation utilizes a moving (rolling) traffic pattern. All products utilized by CTDOT are approved by the Environmental Protection Agency and Department of Energy and Environmental Protection. Extra precautions are implemented where guiderail systems are in proximity to sensitive areas such as wetlands and watersheds.
