Much of the area being marshland, completion of the highway required damming, draining and filling remnants of a distributary known as Bayou Metairie. There was little development other than in two areas. The first hugged the long, narrow ridge of higher ground along Gentilly Road/Chef Menteur Highway, which followed the natural levee of an old bayou. Various farms, plantations, and small villages such as Michoud were sited along this ridge. The other older area of development consisted of a linear strip of "camps", clusters of houses raised high on wooden stilts, in the shallows along the edge of Lake Pontchartrain, the largest and longest-lasting of these being at Little Woods.
