Description	A record rainstorm in late 2000 caused major damage to the only route on the southeast side of the Big Island of Hawaii. The State of Hawaii Department of Transportation chose to replace the 80-foot Route 11 bridge near Pahala with a longer structure to prevent future damage from flooding. The new 7-span, 230-foot concrete bridge, using precast prestressed concrete planks with cast-in-place concrete topping, was in operation within seven months.

Prefabricated Elements	beams
Other Keywords	4-foot-wide by 11-inch-thick precast prestressed concrete deck planks,precast deck panels with topping slab, precast pretensioned partial-depth deck panels
Advantages	Minimized traffic disruption by reducing construction time and limiting lane closures.; Minimized environmental disruption because deck topping did not require shoring or falsework in the streambed, and minimized traffic disruption because precast planks were fabricated during pier construction.
