Oregon State Highway officials wanted a signature bridge to span across the 300 foot deep gorge carved out by the Crooked River. The new four lane concrete bridge is 410 feet clear span and will carry the traffic diverted from the 1926 steel arch bridge which was designed by the legendary engineer, Conde B. McCullough. The segmentally cast-in-place arch was designed so it could be built using tiebacks from a temporary tower. The state pre-qualified construction teams prior to bid and we were selected by one of the contractors for our cable stayed bridge experience to help them get on the bid list. During the tender period, we established that using an 800 foot span cableway to construct the bridge was more economical than using cranes from each bank. After the job was awarded, Somerset performed all of the construction engineering for the arch geometry, cantilever stresses and tieback forces. We also provided the engineering for the cableway, which is owned and was installed by our parent company, KWH Constructors.
