Highway 97 near Klamath Falls at Modoc Point

Infrastructure roadwork and retaining wall construction in Oregon is part of K&E’s DNA. The company’s long history has given us the depth of experience to professionally manage traffic and complexity on any scale. This project, just North of Klamath Falls, included the widening of a 4.5 mile stretch of Highway 97. It required 8,576 linear feet of Oregon retaining wall construction and cast-in-place concrete “moment slab” on top. Another independent task was erecting a reinforced soil slope (RSS) to alleviate rocks falling on the highway and causing hazards to motorists.


Scheduling all excavation and concrete pouring at night to minimize traffic delays was definitely a challenge. Another challenge was the tight quarters of our work zone, which was between a mountain and lake making it difficult to schedule many trades at the same time.


Both challenges were overcome without lost time, accidents or injuries. The result was the successful widening of a major highway connecting Oregon and California—and the building of the largest RSS wall in the U.S.
