Maine Department of Transportation—Gut Bridge in South Bristol

When MaineDOT was faced with the $11 million replacement of an iconic swing bridge across the scenic Gut in South Bristol, the challenges were many including conflicting community values, a highly congested worksite, bedrock with no overburden, and heavy year-round navigation and traffic. Project work included building the actual bridge replacement, construction of an operator’s house, new traffic warning systems, and approach work. MaineDOT utilized a cable-stayed superstructure (which allowed the span to be counterweighted without a cross-counterweight), making wary residents happy with the aesthetically pleasing appearance and cutting the foundation costs. Flood resistant machinery enclosures so that the swing bridge wouldn’t be shut down in higher flood tides, keeping residents connected and safer.Gut Bridge in South Bristol--Maine DOT
