This bridge was originally designed as a 3-span composite pressed concrete bulb-tee with excess vertical underclearance above SR 2008. During the project advertisement, Borton-Lawson realized a single-span bridge design could take advantage of the excess underclear and provided the contractor, HRI, Inc., with a more economical structure to build. The single span structure not only eliminated the construction of two piers, but also negated inspection and maintenance costs on these two substructure units over the life of the bridge.
ChallengeOriginal schedule did not account for any time to complete an alternate design, therefore work needed to be completed within the original project schedule
SolutionWorked diligently to have approved plans in hand for the originally scheduled start of construction.
