Is there a bridge that needs work in your town?

Data from the Maine Department of Transportation presented in a report Wednesday by the industry group TRIP, or The Road Information Program, showed that 15 percent of the state’s bridges have some structural deficiency.

The group and the state DOT are drawing attention to the figures in advance of a bond question on the Nov. 3 ballot whether the state should borrow $68 million for bridge projects and $17 million for other transportation infrastructure, including ports, harbors, aviation, transit and rail.

Attached to that report, TRIP provided a detailed breakdown of the most highly trafficked bridges with deficiencies in the state. TRIP’s detailed list included all bridges that on average support 500 or more vehicles per day.

I put those bridges into a searchable map and database below. Use the map or search bar to filter or a specific town, its structurally deficient bridges and its specific scores.

Each bridge is given a score of 0-9 along three major metrics, evaluating the top deck of the bridge, the underlying superstructure or the substructure that connects with the ground.

For bridges without such a structure, the data assesses the integrity of the underlying culvert on the same scale.

Any bridge with a score of 4 or lower in any one of the categories makes it onto the list of those bridges with some structural deficiency. A ranking of 5 or above is deemed sufficient.

Ted Talbot, spokesman for the Maine DOT, said the report does not reflect bridges that are unsafe but those that need work. He noted the department performs annual reviews of bridges in the state, closing them or posting new weight limits if there are specific safety concerns.
