	Wisconsin Highways: Hoan Bridge 2000
		The Daniel Webster Hoan Memorial Bridge, part of the I-794 Lake Freeway in downtown Milwaukee, was constructed from 1970 through 1972 (though it opened to traffic in 1977) and spans the entryway to Milwaukee's inner harbor and the mouth of the Menomonee and Kinnnickinnic Rivers.
		The bridge was named for Daniel Webster Hoan (1881-1961), the second socialist mayor of the city who was also Milwaukee's longest-serving mayor and is considered to be the longest continuous socialist administration in U.S. history.

	Hoan Bridge - Wikipedia, the free encyclopedia
		The Daniel Hoan Memorial Bridge is a tied arch bridge that connects Interstate 794 in downtown Milwaukee, Wisconsin to the Lake Freeway across the inner harbor.
		This halted completion of the connecting roadways and led to the Hoan Bridge being known as "The Bridge to Nowhere." Its unfinished state was used as the site of the car chase scene in the movie The Blues Brothers.
		The Hoan Bridge was temporarily closed in 2000 after two of three support beams failed, causing the north-bound lane to buckle and sag by several feet, leaving the span in a near collapsed state.

		On December 13, 2000, motorists crossing the northbound approach span of the Daniel Webster Hoan Bridge in Milwaukee, Wis., reported that the bridge seemed to be "buckling." Transportation officials immediately closed the bridge to ascertain the reason for the bridge's 4-foot deflections.
		The Hoan Bridge is a multispan, three-girder bridge constructed between 1970 and 1972.
		Partly because the bridge was noncomposite and partly due to the somewhat large girder spacing of 24 feet, the girders were very large for this span.

	Summary of Hoan Bridge Failure Investigation and Retrofit (Site not responding. Last check: 2007-11-06)
		The Hoan Bridge brittle fracture was the first of its kind ever observed in the United States and is likely to have a nationwide impact on bridges with similar details.
		The investigation of the failure of the Hoan Bridge concluded that the high degree of constraint present at the girder shelf plate assembly resulted in a triaxial condition at these joints.
		A review of the bridge inventory conducted by FHWA and State DOTs to identify structures that have design features similar to the Hoan Bridge indicated that at least 41 States and the District of Columbia have bridges with similar design characteristics as the Hoan Bridge.

	Hoan Bridge buckles; closes indefinitely [Free Republic]
		A 500-foot section of the Hoan Bridge buckled and sagged 3 to 4 feet Wednesday morning, closing the span of I-794 over the Menomonee River for perhaps as long as a year, officials said.
		Two of the three steel beams supporting the bridge cracked near its highest point, causing the span of pavement, about 200 feet from the bridge's crest on the northbound side, to sag, according to Keith Ponath of the Milwaukee County director of highway operations.
		The structural break in the Hoan Bridge was a type that could not have been predicted, said a Milwaukee engineer who participated in last week's assessment.

		The Hoan Bridge carrying Interstate 794 over the Milwaukee River began to visibly sag on Dec. 13, 2000, and was closed the same day.
		"The Hoan Bridge [was] unique in that there was no evidence of fatigue prior to the failure," an investigation by Lichtenstein Consulting Engineer concluded, basically pointing to intersecting welds whose stiffness didn't enable the rest of the steel plates to flex appropriately.

	Bridge Inspection Program [WI]
		Concerns were raised about the adequacy of the Department’s bridge inspection program after three supporting girders of the Daniel Webster Hoan Bridge in the City of Milwaukee cracked on December 13, 2000, resulting in the bridge’s failure.
		A bridge’s average daily traffic count is one factor that determines its condition, and this determines, in part, the amount of federal bridge replacement and rehabilitation program funding the State receives.
		Bridge repair and retrofit costs are estimated to total $15.8 million, and federal funds are expected to pay for 80 percent of this amount.

		The Wisconsin Department of Transportation initiated a comprehensive project to inspect, test, and rehabilitate the Hoan Bridge after observing dramatic cracking of steel girders on the approach spans and other potential safety and maintenance problems.
		On the Hoan Bridge, CTLGroup used a vibration technique to estimate forces in 64 hanger cables (16 panel points; 4 hanger cables per panel point).
		These measured forces were then used to calibrate a finite-element model of the bridge and to evaluate safety and maintenance requirements for the tied-arch span.
