This emergency repair is substantially complete.


Floating Feather Road between Ballantyne Lane and Eagle Road has reopened to vehicles, pedestrians, and bicyclists following the completion of emergency infrastructure repairs.

The sinkhole formed beneath the westbound lane on July 30th, with a surface opening approximately three feet in diameter. Below the pavement, the underground void extends about seven feet horizontally. Veolia initially performed temporary patching over the opening, and flaggers routed traffic into the eastbound lanes during the early assessment. After further evaluation, a full closure was determined to be necessary to immediately begin the extensive work required for long-term repairs.

Veolia crews completed the repairs quickly and safely allowing the road to fully reopen in time for the start of the school year. ACHD extends a big thank you to Veolia for their tireless efforts, including weekend work, to reopen the road before school was back in session.

Commuters should note that another section of Floating Feather Road, between Palmer Lane and Linder Road, will be closed next week for planned underground utility work unrelated to the emergency repairs near Eagle Road. Drivers, bicyclists, and pedestrians are encouraged to follow posted detours and plan alternate routes.

    Veolia crews and contractors worked through the weekend and have continued to make great progress. The water main repairs are completed and the excavation has been backfilled. Water quality samples came back exactly where we expected – all clear – and customers remain in water service. Roadway paving and striping took place on Monday and Veolia will work on sidewalk repairs on Tuesday (8/12) morning. The road is expected to reopen on Tuesday (8/12) afternoon.

    Veolia crews and contractors have made great progress over the last week. The water main was excavated and exposed, over 25 feet below the roadway surface. Safety shoring of the hole walls was installed to ensure our work crews could work safely and effectively. A 20-foot section of the broken 16-inch water main was removed and a new piece installed. The installation was complex and required extensive planning across multiple departments within Veolia and in partnership with ACHD.

    The infrastructure work continues through this weekend, to shore up and backfill the large hole, and then replace the roadway. Veolia appreciates the patience of our customers and the community with the detour and the extensive repairs that were critically necessary.

    Following an evaluation of road conditions after discovering a sinkhole, Veolia has implemented a full closure of Floating Feather Road between Eagle Road and Ballantyne Lane to further investigate the cause and begin permanent repairs.

    The sinkhole formed beneath the westbound lane on July 30th, with a surface opening approximately three feet in diameter. Below the pavement, the underground void extends about seven feet horizontally. Veolia initially performed temporary patching over the opening, and flaggers routed traffic into the eastbound lanes during the early assessment. After further evaluation, a full closure was determined to be necessary to immediately begin the extensive work required for long-term repairs.


    The duration of the closure is currently unknown. A timeline will be provided once the full extent of subsurface damage is determined. Every effort will be made to reopen the roadway before the start of the school year.


    Veolia is coordinating closely with the Ada County Highway District throughout the repair and restoration process. ACHD will continue to monitor the condition of the roadway and support detour management. Traffic impacts and project updates will be shared as new information becomes available.


    The closure applies to all vehicle, bicycle, and pedestrian traffic. Commuters should use either Ballantyne Lane or Eagle Road up to Beacon Light Road (please see the posted detour map). Local access will be maintained for residents.
