U.S. Highway 70 over Lake Raymond Gary - Fort Towson, OK
Crafton Tull prepared construction plans for the replacement of an old two-lane steel girder bridge over Lake Raymond Gary. This 1.5-mile section of U.S. Highway 70 through Fort Towson, Oklahoma begins just west of the intersection of State Highway 109 and extends east past the intersection with State Highway 209. The project included the extension of a triple 10’ x 6’ concrete box culvert, roadway grading, drainage, and paving. The bridge replacement used phased construction and included three 70’ precast beam spans and 80-feet of clear roadway. Portions of the road that pass through Fort Towson were widened to five lanes, with the majority of the widening occurring on the north side of the existing roadway. Wider shoulders and safety features improved the two-lane highway in the more rural areas.
