The
Sharptown bridge over the Nanticoke river was the first bridge built
entirely under the control of the State Roads Commission. It was
constructed in 1912, and was rehabilitated in 1931, 1952, and 1986.
It was replaced by a new bridge in 1987 and was then demolished.
The site was a ferry crossing at
least from the 1750's. In 1910, the State Legislature passed a
Public Highway Act, which specifically provided for funding
$35,000.00 for the construction of a bridge at Sharptown. The SRC
Department of Surveys prepared plans and specifications and awarded
the contract for the bridge on July 31,1911, to the Roanoke Iron and
Bridge Company of Roanoke, Virginia. The Roanoke company was, at
that time, a prolific designer of iron and steel truss bridges in
Virginia and surrounding states.
The bridge was a steel truss
swing span, with a 200 foot + swing span and two 70 foot + Pratt
trusses. The two-mirror image Pratt trusses were connected centrally
by a portion of a Camelback truss. The Pratt trusses were three
panels each, with no secondary diagonals in the innermost panels.
The inner inclined end posts were in the position of diagonals for
the Camelback, which had one central complete panel rising above the
top chords of the Pratts. Over the roadway, between the two central
panels of the Camelback was a platform which supported the the
bridge tender's house, a situation which is rare in Maryland. All
connections were riveted. The swing span was operated by hand crank
when the bridge was first built, and may have been the last large
drawbridge in the State of Maryland to be operated in that manner.
An electric motor was installed in 1913.
The bridge had seven fixed spans,
six at 75 feet + and one at 12 feet +. The roadway width was 17 feet
6 inches + and the vertical clearance over the main channel was 10
feet +. The total length of the structure was 660 feet 8 inches +. |
