Bridge No. L6007 is a single-span stone arch bridge on Skyline Parkway where it crosses Stewart Creek in the southwestern section of Duluth, Minnesota. The bridge is historically significant because of its picturesque design and setting within a city park. [cite web|url=http://www.mnhs.org/places/nationalregister/bridges/nrsl6007/nrsl6007.html|title=Minnesota's Historic Bridges - Bridge No. L-6007|publisher=Minnesota Historical Society|accessdate=2008-09-09] 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 above grade and rising 10 feet over a span of 30 feet. 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 wide.

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