The drive

Highway 31 follows the Bayou Teche south from Breaux Bridge through St. Martinville to New Iberia. Live oaks and old farm structures dot the route, and the road runs along the west bank of the bayou. Breaux Bridge is a bilingual town proud of its Cajun French ancestry.

In St. Martinville the Evangeline Oak stands on the bank of the bayou in Evangeline Oak Park, tied to Longfellow's poem "Evangeline." The drive continues to New Iberia, with town speeds in Breaux Bridge and St. Martinville.

The route is 20.6 miles and takes about 33 minutes, nearly flat with 30 feet of climbing.
