Numbers (WGN) are listed, when known. WGN assigned numbers are coded,
such as 46-03-01. The first two numbers are the assigned State number
in alphabetical order. The second two numbers represent the county
number, also in alphabetical order. The third pair of characters
or numbers is the bridge number. All non authentic bridges, as well
as a few authentic bridges, are numbered with an alpha character in lieu
of the last two digits, i.e., 45-08-A (Vermont's Joe's Pond non authentic
Stringer Covered Bridge).
Covered Bridge (WGCB) numbers have been assigned by the National Society
for the Preservation of Covered Bridges (NSPCB) are referenced for all
listed bridges. Assigned numbers are coded, such as NH-05-12 or VT-115-a.
The first two characters are the postal abbreviations for the state (formerly
digits starting at 01 represented the state in alphabetical order).
The second two digits represents the county in alphabetical order starting
at 01 for each state. The third pair of characters represents the
bridges place in the NSPCB tally of that county's bridges, starting at
01 for authentic truss type bridges or a letter for non authentic type
bridges, an upper case letter for motor vehicle bridges, and a lower case
letter for footbridges. Additionally, bridges that have a leading "(" before
the last letter, are considered O.C.B.I. - "Of Covered Bridge Interest"
- a Covered Bridge that is under 12' or is just on the ground and not over
anything, i.e., 45-12-(b.
Delaware - General
information. Delaware never had very many covered bridges,
and the few historic covered bridges the state had were all located in
the northernmost county of New Castle. In 1937, there were over thirty
five covered bridges, but by 1954, these historic structures numbered only
four; today, only two remain, and these two still carry motor traffic.
Of the six covered bridges in Delaware today, two are authentic historic
covered bridges, and four are non authentic modern covered bridges.
Four covered bridges are located in New Castle County, and one each in
Kent and Sussex Counties. Ironically, the historic bridges are of
similar age, built in 1870 and the modern bridges were built between 1960
and 1987. Both of the two remaining authentic bridges have Town lattice
truss supports. Fortunately, Delaware is maintaining their two historic
covered bridges. The earliest record of a covered bridge in Delaware
is of one built over the Brandywine “Near Wilmington” in 1820-21.
It may have been the single span arch erected near the present Augustine
cut off a short distance northwest of the city. Another was the old
Market Street Covered Bridge in the center of Wilmington. It was
a double-barreled bridge with encased arches, false front portals and twin
side walks, and a Wilmington Landmark until 1889. In Rising Sun there
was a Powder Keg Mill and cluster of workers’ homes with another twin lane
span high above the Brandywine. This bridge, built in 1833, had a
useful life of well over eighty years. Further upstream were Rockland
and Thompson’s Bridges, which survived until recent years. The most
unusual of Delaware's covered bridges was the one that crossed the famed
Deep Cut on the Cheasapeake and Delaware Canal. Twenty-five hundred
men dug and blasted through a ridge of solid rock nearly a mile long to
create this gash. Even before the canal was completed, the cut was
spanned in 1825 by a graceful wooden arch some 90 feet above the water.
This covered bridge, with its ornate windows and boxed portals, became
a landmark to helmsmen guiding their canal boats behind plodding mules
along the old waterway. Known as both Buck’s Bridge and Summit Bridge,
the high span was replaced in 1872 by a swing draw bridge at a lower level.
Northeast of Granogue, and only a few paces from the Arc of the Northern
Boundary, is Smith’s Bridge, the best preserved of Delaware's remaining
authentic covered bridges. Built in 1839 at a cost of $5,446.00,
this 154 foot bridge with its concentric arches carries a good deal of
traffic across Brandywine Creek. The structure was completely rebuilt
