To repair the concrete in sections, there will be single lane closures and crossovers to isolate the construction workers and equipment from the traffic. Drivers should expect slow moving traffic and possible back-ups, especially during holiday weekends and on the climb up to Siskiyou Summit. Because the location is in a snow zone—with Siskiyou Summit at 4,310 feet—construction timelines are limited to the late spring through the fall. Deck Replacements While staging will be challenging with the roadway repairs, it will become even more so in the final two years of the project with the full deck replacement of the twin bridges over Old Siskiyou Highway at Exit 6.

the construction. In addition, the crossing under the bridges will be closed for a short time. That will result in out-of-direction travel for residents living on both sides of Interstate 5. Residents east of the interstate may have to use Old Siskiyou Highway down to Oregon 66 for a time. For those on the west side of the interstate, it may include a trip to Hilt, California and back north toward Ashland. “We realize this will mean delays and out-of-direction travel for a time,” said Hunter. “For the first major project of its type in 33 years, we’re asking for understanding as we do the needed work.”

Like previous deck projects, traffic will be shifted onto one bridge while the other is being rehabilitated. On the bridge being worked on, the entire bridge deck surface will be replaced, except for the bridge beams that support the deck. The second year, the other bridge will be under construction. “Project staging and keeping everyone connected will be challenge,” said Project Manager Chris Hunter. “Interstate traffic will need to be slowed, especially those trucks coming down the grade at the crossover. At the same time, a single lane of traffic for trucks going up the grade will mean some back-ups.” Depending on the stage, Exit 6 ramps will be closed to facilitate
