context_page_description: The Covered Bridge in Cedarburg, Ozaukee County, Wisconsin, United States, is one of the last remaining covered bridges in that state, which once had about 40 covered bridges. Built in 1876 to cross Cedar Creek, the bridge is 120 feet long and is made of pine with oak lattices. It was listed on the National Register of Historic Places in 1973 and is now used only for pedestrian traffic.
context_section_description: The Covered Bridge is situated in a north-south orientation over Cedarburg Creek.  It is a timber lattice truss bridge, and was originally 120 feet (37 m) long.  It is 17 feet (5.2 m) wide, and has a height of about 18 feet (5.5 m) from the top of the abutments to the tip of the roof.  The interior, from the deck to the top of the knee braces is approximately 13 feet (4.0 m).
  It was built using oak and pine timbers, wood that was prepared at a site near Baraboo, Wisconsin.  The lattices are very large, made of oak, and were assembled without the use of bolts or nails.  Instead, the trusses, consisting of 3-by-10-inch (76 by 254 mm) planks, are secured at the joints using oak pegs measuring 2 inches (51 mm) in diameter, and having rounded ends.  The boards used at the sides and ends measure 1 by 12 inches (25 by 305 mm), and have joints covered by 1-by-4-inch (25 by 102 mm) battens.  There are diagonal braces that measure 4 by 7 inches (100 by 180 mm), and are tenoned to fit into cross tie beams, and fitted with 2-by-2-inch (51 by 51 mm) oak wedges.
  The roof is shingled with cedar over 3-by-4-inch (76 by 102 mm) rafters spaced 30 to 36 inches (760 to 910 mm) apart.  The cross tie beams at the floor are notched and bolted at each end.
  The floor joists, measuring 6 by 8 inches (150 by 200 mm), are decked with 2-by-4-inch (51 by 102 mm) wood laid on edge forming the deck.  The interior walls were lined with a protective wheel guard about one foot above the deck.
  The abutments are made of fieldstone set in white mortar. They are 17 feet (5.2 m) wide where they meet the deck of the bridge, widening toward the ground to about 18 feet (5.5 m).  The center abutment was originally also made of fieldstone, but sometime before 1937 was replaced with concrete.
