Foundation design and construction challenges at river crossing for 345 kV transmission line

River crossings are inevitable when designing and constructing foundations for cross-country transmission lines. Factors such as dramatic terrain changes, long spans, heavy loading, and unfavorable soil conditions create significant challenges for engineers and contractors. This paper will present a case history of one particular river crossing on the CapX2020¹ Brookings County to Hampton 345 kV Transmission Project and how the design team worked with the contractors to overcome several obstacles to construct the foundations.
