Ascension’s Dewey Breaux Road reopens to traffic Ascension’s Dewey Breaux Road reopens to traffic River Parishes bureau Aug. 29, 2013 Comments GONZALES — Dewey Breaux Road in Ascension Parish reopened to through traffic Tuesday with completion of a bridge replacement project that had forced a two-month closure, parish officials said. Parish crews demolished the old bridge over the Calbasse Canal on Dewey Breaux and built a new crossing with box culverts, Lester Kenyon, parish government spokesman, reported Tuesday. The old bridge was in poor condition. The $62,120 demolition and replacement project began Aug. 6. The road will be given a new layer of asphalt at a later date. Dewey Breaux is a residential street that runs south off La. 621 about a half-mile west of the La. 621/La. 44 intersection. The road was closed June 27, but a one-lane access lane had remained for neighborhood traffic and emergency vehicles.
