• Total $6.4 million project involved the removal and replacement of the Highway 11 bridge over the CN railroad tracks in Koochiching County.
• New bridge and approach have increased width (10-foot wide) paved shoulders.
• New bridge will provide greater vertical clearance and width over the CN railroad tracks.
• Settlement of the roadway was anticipated at the bridge during design. This settlement was mitigated using UL-FGA lightweight fill.
• A geogrid-reinforced UL-FGA layer along the shoulder of the approach embankment was constructed to alleviate settlement and slope stability concerns.
