Newest Bridge

In 1932, construction began on a bridge to take Old Highway 84 (now CTH H) over the Sauk Creek and Union Pacific Railroad. In order to do so, the creek had to be moved about 200 feet south to make it closer to the tracks and the road was raised from its original elevation.

The old structure was a 10-span bridge with steel girders, steel girders encased in concrete, and concrete beams. Using a useful bridge life scale between 0 to 100, the bridge rated 8.6. With a rating under 40, the bridge could be replaced using federal money distributed through the Wisconsin Department of Transportation.

Ozaukee County hired the Milwaukee engineering firm of Graef, Anhalt, Schloemer & Associates, Inc. (GAS) to design a new bridge and reconstruct the approach roadways.

 A concern during the design was how to minimize erosion of the creek banks. The retaining wall on the northeast corner was failing and had to be removed. It was replaced with heavy stones over a geotextile fabric. A retaining wall was needed on the west side of the road to protect existing buildings at the bottom of the slope when more fill material was added on the road to provide additional clearance over the railroad. Also, two piers of the old bridge were left in place to protect the banks and to minimize any disturbance.

The new bridge is a four-span, 278-foot, prestressed concrete girder bridge that will have low maintenance requirements. The three pier columns are solid concrete in a "hammerhead" shape. The bridge was raised to provide a 23-foot clearance in accordance with railroad requirements. The new bridge deck is approximately 3.5 feet wider than the old one.

In the fall of 1999, the new bridge was opened without fanfair. The total construction cost of the bridge and approaches was $768,000. Ozaukee County paid 20% of the bill, with 80% coming from federal and state funding.
