The report covers the construction of the guardrail, at MP244.7 on Interstate 70, west of Denver, Colorado. The modified thriebeam guardrail is used as a transition from the standard w-beam guardrail to the SERB guardrail, and back to the w-beam guardrail. Problems encountered in the installation was the difficulty in driving the wood posts. The Post Driving Equipment (PDE 1500) was not designed to handle 10 ft posts, and the soil conditions consisted of large boulders in the fill areas which caused erratic driving of the wood posts.
