Nature and history offers the main attractions and points of interest along this route, which tracks Bayou Teche for much of the way. Keep an eye out for wildlife. You’ll find moderate traffic in Franklin and some busy streets as you work your way through Patterson. Highway 90 has considerable traffic, but you will have a wide shoulder. Bayou Vista has moderate traffic but a shoulder begins at the 21-mile point.
Patterson offers a good stopping place. There you can visit the Louisiana State Museum and its Wedell-Williams Aviation Collection, which marks the site where Jimmy Wedell and Harry Williams founded the state’s first commercial airline. Their aviation designs set speed records during the early 1930s. At the 19-mile point, you'll see signs reading "St. Mary Parish Tourist Commission" and "Cajun Jack Swamp Tours." If you have time, take a boat tour of the Atchafalaya Swamp and learn about the Cajun culture of the marshlands, including fur-trapping, crabbing and crawfishing. In Morgan City, stop by lovely Brownell Memorial Park.
