The 1876 Cedarburg Covered Bridge in Ozaukee County, Wisconsin, is the last remaining original covered bridge in that state which once had about 40 covered bridges. Originally called Red Bridge, this 120-foot long, two-span, bridge made of pine with oak lattices was built to cross Cedar Creek. Situated in a north–south orientation, it is 17 feet wide and has a height of about 18 feet 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.

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 planks, are secured at the joints using oak pegs measuring 2 inches in diameter, and having rounded ends. The roof is shingled with cedar over 3-by-4-inch rafters spaced 30 to 36 inches apart. The cross-tie beams at the floor are notched and bolted at each end. The floor joists, measuring 6 by 8 inches, are decked with 2-by-4-inch 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 wide where they meet the deck of the bridge, widening toward the ground to about 18 feet. The center abutment was originally also made of fieldstone, but sometime before 1937 was replaced with concrete.

The bridge was built as a result of a petition by area farmers as a permanent replacement for previous bridges that had washed out on various occasions. In 1927, an abutment was added under the center of the bridge to support heavier vehicle traffic, such as cars and trucks, which were not present at the time of the original construction.

The Ozaukee County Board took over the bridge's preservation and maintenance in 1940 and in 1960, Ozaukee County bought the bridge and surrounding land for $7,500 and developed the area into Covered Bridge County Park.

After nearly a century of continuous use, the bridge began to suffer, with heavy traffic loosening the planks. It was decided that the only way to preserve the bridge was to alleviate the burden. In 1962, the Park Commission made the choice to relocate the bridge by moving it off the abutments to a location approximately 50 feet east of where it was and restricting it to pedestrian traffic. A second, modern bridge was built beside it to the west, only a few yards away for all vehicular traffic on Covered Bridge Road.

In 2009, the county planned to spend over $19,000 on capital improvements for the Covered Bridge County Park, with part of the money to be used for new decking and railings for the bridge.

A replica of the Covered Bridge named the Springwater Volunteer Bridge, was built in 1997 in Waushara County, Wisconsin.

Cedarburg Covered Bridge was listed on the National Register of Historic Places on March 14, 1973.
