Emergency Response to Rockfall on Oklahoma Interstate 35

After heavy rains had impacted the Oklahoma region, a large rockslide occurred along a stretch of northbound I-35, a main traffic artery between Oklahoma City and Dallas, TX. A section of rock slope gave way; leaving large amounts of fallen debris that blocked the interstate and causing a significant safety hazard from additional slope failure. Remnants of the collapsed cliff above remained unstable and poised to fall at any time. This paper discusses how a partnership between contractors and the State Department of Transportation resulted in safe reopening of the highway while solving significant engineering and operational challenges that occurred almost daily. Additionally the methodology used to develop the design mitigation plan is presented and described in detail.
