Seventh Street Improvement Arches

Seventh Street Improvement Arches is a stone bridge with two arches that spans across the former railroad tracks in Saint Paul. The structure connects downtown with Dayton's Bluff neighborhood and now carries pedestrians and cyclists over the old rail line.

Engineer William Truesdell designed this bridge in 1883 as a replacement for a deteriorating wooden structure. The construction improved connections between two neighborhoods in expanding Saint Paul.

The bridge earned recognition from the American Society of Civil Engineers as a Historic Civil Engineering Landmark in 2000 for its technical achievements.

Visitors can cross the bridge on foot or by bike and access surrounding trails and neighborhoods easily. The structure is open year-round and works as a natural link between different parts of the city.

The bridge was built with gray limestone from local quarries and buff-colored Kasota limestone, showcasing advanced engineering techniques. This material combination and the spiral arch design make the structure technically notable.
