     Simms St. Sinkhole Update

    07/15/2014 - Repairs to the Simms St. sinkhole are continuing. Simms St. has been closed again to facilitate the repairs and for the safety of motorists. Simms will remain closed for the foreseeable future. Detour signs are in place to direct traffic around the closure. 
    The repair work consists of pushing a new 48” steel culvert through the failed culvert as a first step. Several state and federal permits needed to be obtained prior to any work commencing on the replacement pipe. Those permits are now in place and the culvert repair work is being accomplished from the east to the west for a distance of 175’. The sinkhole cannot be filled in and the asphalt repaired until this new drainage pipe is in place and functioning properly. The casual observer will not notice any work being done on the sinkhole itself for the next two weeks while the replacement drainage pipe is being installed. All schedules are weather dependent and do not take into consideration unforeseen conditions that may develop.
