Sailboat Bridge over the Grand Lake O' the Cherokees was the first precast concrete segmental bridge in Oklahoma. The precast concrete box girder design resulted in a savings of $1M when bid against a Bulb-T alternate. The new southbound bridge incorporates portions of the original bridge piers, saving over $2.7M. In addition to the cost savings, Oklahoma DOT realized greater aesthetic value, increased durability, and minimal maintenance requirements due to design features of the post-tensioned structure. The design includes the use of an integral wearing surface which far exceeded the standard for rideability in the state. The 3,044’ long twin bridges were completed more than two months ahead of schedule. The 27 span, 42’ wide structures have typical span lengths of 122’ and were constructed using the precast segmental span-by-span construction method. The bridge was precast at a plant created specifically for this project on the shore of the Grand Lake O’ the Cherokees
