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.

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.

There are two common types of bridge posting: vertical clearance and weight. Both postings require signs on or at the bridge, and advanced warning signs.

The Frank J. Wood Bridge (#2016) carries Route 201 over the Androscoggin River on the Brunswick-Topsham town line. MaineDOT and the Federal Highway Administration (FHWA) have concluded the National Environmental Policy Act (NEPA) process.
