The Dumaine Street Bridge is a sixty-year-old fully-functional vehicular bridge that is in need of repair and beautification. Built by the City of New Orleans in 1951 at a cost of $43,349, this bridge is located where Dumaine Street crosses Bayou St. John.

Although structurally sound, the bridge requires some corrosion remediation, concrete repair, and paint.The roadway of the bridge is steel stringer framed, and there are structural concrete supports for the steel guardrails and pedestrian curbs. Although structurally sound, the bridge requires some corrosion remediation, concrete repair, and paint.

The graceful design of the Dumaine Street Bridge is reminiscent of the artistry of the Works Progress Administration program, which provided extensive infrastructure work to the Faubourg St. John section of the Bayou during the 1930s. Hand-drawn blueprints and detailed drawings of bridge elements are archived at the New Orleans Public Library, along with extensive documentation of a proposed “Bayou St. John Aquatic Park”.

The Aquatic Park concept was one of many development efforts led by Walter Parker, president of the Bayou St. John Improvement Association from 1927–1950. Mr. Parker resided at 924 Moss St., directly in front of the Dumaine Street Bridge. The historic house, built in 1798, is currently known as The Sanctuary. Mr. Parker died in 1950, after which his widow, Anita Hernandez Parker, continued to pursue his vision of converting the character of this portion of Bayou St. John from heavy industrial to prime residential. A year after his death, the City of New Orleans honored these efforts by naming the new Dumaine Street Bridge the Walter Parker Memorial Bridge.
