    Sinkhole on Simms Street in South Jeffco


    Update: Monday, July 14, 2014 

    The Jefferson County Road & Bridge Division is continuing work to repair a sinkhole that occurred in June on Simms Street just south of Coal Mine Road in South Jeffco.

    The cause of the sinkhole, which measures about 20' x 20', appears to be the failure of a large drainage culvert under the roadway. 

    Traffic has been moving on the western side of Simms while repairs were being made to the sinkhole, however, the county now needs to close the road to all traffic beginning at 9 a.m. Tuesday, July 15.

    Jeffco Road and Bridge Director Larry Benshoof said that continuing repairs to the roadway require the road to be fully closed until such time as it is safe for two-way traffic to resume.
       



    Update: Thursday, June 26

    The Jefferson County Road and Bridge division is currently shoring up the west side of the 20' x 20' sinkhole (area of 400 square feet) in order to protect the traffic lanes running next to it. Traffic is running smoothly in both directions at this time with one lane in each direction on the west half of Simms.

    They are meeting with qualified contrators today and will have a contractor in place by the end of day tomorrow. The status of the site will remain static until there are required permits in place and the contractor can begin permanent repairs.

    Please see the status updates and upcoming full closures posted on the Jefferson County Road & Bridge website. 
     


    Wednesday, June 25

    A sinkhole opened up this morning, Wednesday, June 25, just south of West Coalmine Avenue on South Simms Street.

    With a portion of that road collapsed, Simms Street is now closed between West Cooper Avenue and South Ward Street. It is projected that the western half of Simms will be opened by 8 p.m. this evening, allowing for a single lane of traffic in both directions. Click on the map and photos to the right to see those images in a larger view.

    The cause of the sinkhole appears to be the failure of a large drainage culvert under the roadway. Due to the size and depth of the culvert, permanent repairs may take up to 30 days to complete. Intermittent full closures may be necessary for limited time periods in order to complete the permanent repairs.

    Status updates and upcoming full closures will be posted on the Jefferson County Road & Bridge website by 5 p.m. for the following day’s closure.
