In 1940, the tallest bridge in the south--today it is known as Rainbow Bridge--was completed and aided in the growth of Prairie View. In the 1940s, with the increase in traffic because of the bridge, Praire View started to resemble a town; the area featured a horse race track, multiple grocery stores, two dairies, and gas stations. According to the Historical Society, [t]he first post office was completed in 1946, and by 1952 the estimated population was 3,000. The channelization of Cow Bayou, the completion of the private electric plant in 1962, and the presence of nearby oilfields and petrochemical plants aided industrial growth.
In the 1941, the Prairie View School District and the Winfree School District joined together and was called the Bridge City Consolidated School District as suggested by a group of ladies at a quilting bee. In 1959, the Bridge City Chamber of Commerce formed and touted the town's new slogan:“The Home of the Friendly People on the Grow”. Community members resisted incorporation in 1960, but another attempt by the Orange County Commissioners in June of 1970 proved to be successful.
