The "tree tunnel" is a memorable stretch of 12th Avenue between Barcia and Driftwood Drive (near the merge with Fairfield) in which the limbs of large oak trees have been cultivated to form a canopy over the road.
The road was originally the entrance to the Baars family's vast estate, including their Bayou Texar home, Cordova Towers. The trees were planted in anticipation of Mary Ellison Baars' plan to develop the area with vacation homes for wealthy northerners, but that project fell through when economic conditions soured in the early 20th century.
