Historic Covered Bridges

There are no records of the men who built Maine's covered bridges. Available town documents show that the chief concern of the thrifty citizens at town meetings was the amount of money their new bridge was to cost - which was entered to the last odd cent - and a brief line or two about its manner of construction.

Historic Bridges in Maine

In 1959, the 99th Maine legislature took a major step by enacting a law to preserve Maine's wooden covered bridges. The new law provided that state money could be used to save and renovate covered bridges. As a result, in 1961 the Department of Transportation undertook major renovations to the 10 remaining covered bridges.

Inspections

The Maine Department of Transportation (MDOT) inspects all bridges and minor spans on public ways every two years in accordance with the National Bridge Inspection Standards (NBIS) (PDF) and MaineDOT’s Bridge Management Coding Guides. The collected data (for bridges only) is reported annually to the Federal Highway Administration (FHWA) and is used for determining safe load capacities and candidates for MaineDOT’s bridge capital and maintenance work.
