POWELL (WNE) — After some large rocks fell onto U.S. Highway 14/16/20 west of Cody last month, Wyoming Department of Transportation geologists climbed up the cliffs on Monday to see if there was a potential of further danger.
WYDOT says the workers found evidence that more rocks could fall on the eastern (Cody) side of the tunnels that lie near the Buffalo Bill Reservoir.
“We have remaining rock above the roadway that is still unstable,” WYDOT Principal Geologist David Vanderveen of Cheyenne said in a Wednesday news release.
The rock slide that triggered WYDOT’s Monday inspection occurred on Dec. 27 on the east (Cody) side of the tunnels near the Buffalo Bill Reservoir. The falling rock damaged guardrails and blocked one lane, disrupting traffic for part of the day.
WYDOT has put up cautionary signs on each side of the area.
The transportation department is bringing in contractors this week to assess the area and bid on the work of mitigating the risk of falling rocks.
“When a contractor is chosen to mitigate the rockfall hazard, we will ask them to conduct several days of rock scaling to remove the loose rocks,” Vanderveen said.
Traffic delays are expected.
