Bridge No. L6007
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. 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 above grade and rising over a span of .
pedestrians used the bridge, the Mansfield Bridge has a load limit. The bridge had been used for State Route 59 and in one recorded story, three loaded oil trucks approached the bridge together. The first truck stalled out just before leaving the bridge, and all three trucks came to a stop on the two spans. There was no apparent damage to the strong structure. The arches combined with the truss are able to support more weight than needed so the limit is in the decking and material used for it.
