Lake Resort Drive

After reports of unusual roadway settlement and separation, CDOT closed Lake Resort Dr. from the roundabout at Hwy. 153 to Lake Resort Ter. on 23 February 2019. CDOT staff visually inspected the condition of the roadway and slopes adjacent to the roadway. Inspections indicated that the westbound lane was stable, so it was reopened 24 February 2019. The eastbound lane remains fully closed while signals alternate passage for westbound and eastbound traffic utilizing the westbound lane.

Since establishing measurements at the site on 24 February 2019, inspections and measurement data indicate the roadway area continues to rapidly shift. CDOT engineers continue to inspect the site at least weekly, more often with rainfall. The stability of the westbound lane, the lane currently being used as an alternating lane for both directions of traffic, is closely monitored to ensure continued public safety.

CDOT staff are working to ensure the continued safety of all people who use Lake Resort Dr. and to permanently resolve the issues associated with the subsurface failures. See below for details of actions that have been taken and a timeline for repairs to Lake Resort Dr. Schedule is subject to change.

  • Notification of slope failure: 23 February 2019
  • City staff monitoring of site: 23 February 2019 and ongoing
  • Initiation of emergency contract: 06 March 2019
    • CDOT engaged the services of the consulting engineering company Geosyntec Consultants, Inc. to assist with the development of a permanent repair of the roadway.
  • Lab analysis of samples and field data analysis: April 2019
  • Preliminary design development: April - May 2019
    • Geosyntec will prepare three recommended options for repair, including the general cost estimate for each option.
  • Detailed design development: May - July 2019
    • Geosyntec will prepare all design calculations and construction documents for the selected repair
  • Meeting with FHWA and TDOT regarding next steps related to federal funding: October 30th, 2019.

Following the meeting on October 30th, 2019, FHWA and TDOT will review the project history and documentation and make a determination on how the city should move forward towards a solution. This process may take several weeks. Once a path forward has been defined, a project schedule will be developed.

For those drivers who rely most on Lake Resort Drive for access to their homes on Big Ridge, we apologize for the inconvenience that the limited one-lane is currently causing. It is important to continue to monitor the shifting of the downhill lane because the settling that is occurring on this lane was not permanently resolved by the major repairs that were made in late 2014. It is necessary for the CDOT team, as well as the consultant, to be able to monitor the change so that we can completely and accurately diagnose the geotechnical issues and develop the appropriate engineering solution. CDOT endeavors to permanently resolve the issues associated with subsurface failures. We believe moving hastily to fix the roadway to allow for full re-opening of traffic could potentially result in an incomplete fix that could result in further issues in the future. We rely on the exposure of the roadway to fully diagnose the solution.

The federal government recently declared the storms of February to be a national disaster, which allows federal assistance to help with repairs for several streets, other slope repairs, and other aspects of flood damage. The City’s first priority is to assure the safety and long-term resiliency of our street network. To that end, in addition to ongoing engineering work by our consultant, CDOT staff continue to conduct regular site inspections, take measurements, and monitor survey data of the site to ensure that the existing conditions are safe and the roadway can continue to be used in its limited capacity.
