Explorer Pipeline was directed by the Oklahoma Turnpike Authority to relocate a portion of their 28” pipeline in the western portion of Tulsa County in Oklahoma due to the proposed construction of a new tollway. The project consisted of two conventional bores under West 41st Street South and under the existing Gilcrease Expressway, an extension of the 34 in casing under West 51st Street South, and approximately 2,820 ft of 28” pipe.
