A rebar splicing technique was a major factor in saving two year's construction time on California's $33 million, 9000 ft (2743 m) Antioch Bridge. Rebar splicing consists of taper threading the ends of a standard rebar and connecting the rebar ends with a threaded coupler. This reduces field installation and testing time as compared to commonly used sleeve-filler type of coupling. Steel is ready for form lifts as soon as concrete is cured.
