TWIN FALLS, Id ( KMVT-TV / KSVT-TV ) Crews were working to repair a second sinkhole along the Canyon Springs Grade Monday.

The city and Public Works Department are filling and patching the roadway as quickly as possible. While the work is taking place, Canyon Springs Road will be restricted to one lane, and drivers should use caution and expect delays.

Another sinkhole was discovered earlier this month near the same spot. Both sinkholes are believed to be caused by water runoff from the canyon rim. The repairs are expected to be completed by Thursday, September 17th.
