VIADUCT ERECTION IS FAST DESPITE ESTHETIC FOCUS

After taking nearly a year to mobilize, a contractor is completing a 1.3-mile prestressed concrete viaduct in Riyadh, Saudi Arabia, in about 15 months. Segment precasting was complicated by the unusual design, dictated by esthetics. The bottoms of the precast segments are multiply curved and flow down into the footings, so their cross sections change constantly. The pair of three-lane structures contains 1200 segments ranging up to 143 tons. Twin main spans of 427 one-half ft are flanked by shorter ones. The Gulf Street Viaduct is part of a $112-million project running about 3 miles adjacent to the old airport at the northern edge of the city.
