Bridge No. L6007 is a single-span stone arch bridge on Skyline Parkway where it crosses Stewart Creek at the Smithville neighborhood in the southwestern part of the city of Duluth, Minnesota. The bridge is historically significant because of its picturesque design and setting within a city park.[2] It is built of locally quarried dark green gabbro, which is abundant in the Duluth area. The single arch over a deep ravine is built on rubble abutments, springing about 7 feet (2.1 m) above grade and rising 10 feet (3.0 m) over a span of 30 feet (9.1 m). The rubble spandrel walls continue back in straight lines to form the retaining walls for the approaches. The bridge railings are topped with double sawtooth-shaped rows of gabbro. Overall, the bridge is about 29 feet (8.8 m) wide.[3]

The bridge was listed on the National Register of Historic Places in 1989.
