Sailboat Bridge

This twin structure will replace the existing US 59 over Grand Lake in Delaware County, Oklahoma. Both structures are 297 meters long with 37.1-meter spans and each carry two lanes of traffic with shoulders and a sidewalk. The northbound bridge was constructed first and traffic will be shifted to the new northbound structure and then the southbound bridge was constructed on the existing bridge foundations.

Each span consists of six typical segments that are 5.58 meters long and 12.62 meters wide. There is a 160-mm cast-in-place closure joint between the pier segment and typical segment.

There are a total of 356 precast segments including the pier and expansion joint segments. The precast segmental superstructure was erected span-by-span using twin triangular trusses. The segments joints are epoxied and compressed with temporary post-tensioning bars prior to stressing the permanent external longitudinal tendons located inside the box girder.

Construction of the Sailboat Bridge began in December 1997 and was completed in March 2001. The contractor’s bid was $20 million.
