The MDT Judith River Trestle Design-Build project was a rebuild of a 100-year old-train trestle bridge that was damaged by flooding in 2011. The floods changed the alignment of the river and twisted the bridge’s piers, which twisted the tracks and disabled a leg of the railroad. The Judith River Trestle is a 2000-foot-long, single-track, ballasted railroad bridge structure. The trestle is located approximately 13 miles northwest of Lewistown, Montana, and traverses the Judith River. Damage to the trestle, which varies in height up to 140 feet, including the undermining of eight concrete foundation piers and rendering the trestle unusable for rail traffic. The repair consisted of removing and replacing two four-legged steel towers, eight of the existing concrete piers, and precast concrete pans that the rail rested on.
What makes it interesting?
Challenges included determining whether certain components were reusuable, dealing with current lead-based paint, and large equipment access to the river bottom. This project was constructed over the winter in an area with high winds, and work performed by the crane had to be completed quickly in order to avoid snow runoff.
How HCSS Software assisted with this project
HeavyBid provided the bidding infrastructure to quickly make changes on a design build project. There were numerous design changes in this intricate design and as these changes were contemplated by the client, we had to continually provide updated pricing and HeavyBid allowed us to do this in an efficient manner. Our quick responsiveness allowed us to become the preferred proponent and we were awarded the project.
