Murrow Floating Bridge (LVM Bridge) on Lake Washington in Seattle, Washington. The LVM Bridge is 2013 m (6,600 ft) long, consisting of 20 prestressed concrete pontoons rigidly connected to form a continuous structure. A typical pontoon measures 110 m (360 ft) long, 18.3 m (60 ft) wide, and 5.4 m (17.85 ft) deep. About 38,000 cu m (49,60 cu yd) of high-performance concrete went into the construction of the pontoons. The high-performance concrete contains silica fume and fly ash, and its average 28-day compressive strength is more than 69 MPa (10,000 psi). The high-performance concrete has low permeability and low shrinkage. The contractor learns to work with the high-performance concrete by constructing test sections. The lessons from the test sections are put into practice, resulting in improved placement, finishing, and curing procedures. The construction of the LVM Bridge has shown that it is feasible and cost-effective to use high-performance concrete in highway structures for which high strength, impermeability, and durability are of prime importance.
