Old Siskiyou Highway will reopen Friday afternoon, following repairs to an active slide that required a temporary closure of the highway.

ODOT maintenance crews installed a new, larger culvert and raised the roadbed. According to ODOT District Manager Jerry Marmon, the section of highway near mile post 6 is passable to all vehicles but will remain unpaved for the time being.

"This slide is fixed but it is only a temporary fix," Marmon said in a prepared statement. "Motorists still need to drive with caution because the ground is unstable.

He said that contract drillers will be on site later in July to install instruments, to monitor the water table and slope movement in and near the roadway. The instruments will gather information that will help geologists determine what type of long-term repair is necessary.

Old Siskiyou Highway was closed May 1 to allow the ground to dry enough to begin slide repairs. Motorists used a detour from Interstate 5 to exit 6 or Highway 66 to Old Siskiyou Highway. The detour added about five minutes to local residents' commute, ODOT officials said.
