The August–September issue of Tunnels and Tunnelling, official publication of the Tunnelling Association of Canada, features a cover story on Barr’s repairs and restoration of the Trout Brook interceptor in Saint Paul, Minnesota. The article details repairs to a portion of the historic limestone tunnel that included replacing the mortar and improving structural integrity while retaining much of the tunnel’s original aesthetic. Barr’s Joe Welna and Nathan Campeau are quoted along with Anna Eleria of the Capitol Region Watershed District, which owns the 129-year-old tunnel.
