Kenilworth bridge concepts are nod to nature, railroad heritage

Date: Tuesday, November 25, 2014

Three bridge concepts presented today for the Kenilworth channel crossing on the Southwest LRT (METRO Green Line Extension) would reinterpret the existing wooden railroad bridge with new low-profile structures.

The project designers’ concepts feature arches, angled piers and a thin deck reminiscent of the existing railroad bridge and are fashioned to fit in with the natural surroundings, as initially recommended by several parties. These parties include the Minnesota Department of Transportation, the State Historic Preservation Office, the Minneapolis Park and Recreation Board, the city of Minneapolis and Kenwood Isles Area Association. Structural engineers tested the concepts, and designers presented them today to these parties and staff of the five corridor cities and Hennepin County.

“These are not full-blown designs. They are just in the idea stage for discussion as part of our consultation process for historic properties,” said Jim Alexander, director of design and engineering for the Southwest LRT Project.

To minimize the visual impact and hazards for channel users, all three bridge concepts would be supported from below only with just three rows of piers, down from the six on the existing wooden railroad bridge.
