The Authority’s largest structure continues to take shape in Kings County. Crews are more than halfway done at placing the 978 pre-cast concrete girders needed for the superstructure. On the north side of the viaduct, ironworkers, carpenters and cement masons are working together to form the deck of the structure. To date, more than 16,000 cubic-yards of concrete has been placed at the Hanford Viaduct. Further south, Lacey Boulevard has been temporarily closed, and State Route 198 has been slightly realigned toward the median to allow crews to begin extending the viaduct over the highway.
