Description
The following excerpts are from a report written by the Historic American Engineering Record for the Iowa Department of Transportation between the summers of 1995 and 1996."Then, as now, the bridge consisted of a three-span cantilevered through truss of approximately 1,127', comprised of two cantilevered units of about 415' and one suspended span of about 297'. Each cantilevered unit consists of an anchor arm of about 237' with a cantilever of about 178'. The two cantilevers and the susepended span provide a channel crossing of about 653'. The cantilevered units are carried by concrete piers supported by foundation piles. The bridge was originally about 25' wide with an apprioximately 22' roadway. The original bridge floor was of sheet asphalt plank on treated timber plank supported by steel beams. Acording to the Prospectus issued in 1931 to obtain financing, the bridge was designed to accomodate 2,300 vehicles per hour with a maximum vehicle load of 30 tons. Pictures provided by The Book of the Black Hawk Bridge, a promotional document produced for the dedications ceremony in 1931, indicate that the entire bridge project, from Second Street, Lansing to the Burlington railroad tracks at the foot of the Winneshiek Slough and several smaller bridges over the Henderson, Stevens, Indian and Big sloughs. The road bed between the main span and the Wisconsin bluffs was paved with crushed stone. There were no approach spans on the Iowa side of the river. There was a toll booth at the Iowa end of the bridge, located immediately adjacent to the southwest end.
"Although the Black Hawk Bridge does not serve any primary routes, it provides a regionally important vehicular crossing of the Mississippi River midway between La Crosse, Wisconsin and Prairie du Chien, Wisconsin. According to bridge consultant Clayton Fraser, it is only one of five long-span cantliever truss bridges remaining in Iowa." "A reality! Finished!" The Book of the Black Hawk Bridge, enthused at the structure's dedication in 1931. "The Black Hawk Bridge, three quarters of a million dollars of steel and concrete, linking the states of Iowa and Wisconsin, running eastward from Lansing across the Winneshiek Bottoms to De Soto, is a reality. It is the first passenger bridge to join these two states, the result of more than a generation of dreaming and scheming, planning and promoting--and two years of actual construction." Planning for the bridge had begun in 1898 by Lansing businessmen J.P. Conway and Tom Bakeman. The two promoted the proposed structure for years as a boon to the community, eventually forming the Interstate Bridge Company in 1914 to secure a Congressional charter for the bridge. The charter, secured in 1916, was turned over to the Iowa-Wisconsin Bridge Company in late 1929. Under the direction of Des Moines financier John Thompson, the latter firm sold bridge bonds to finance construction, hired Minneapolis engineer Melvin B. Stone to design the bridge, and contracted with the McClintic-Marshall Company of Chicago to fabricate and erect the trusses. The bridge was christened the Black Hawk Bridge to honor famous Indian Chief Black Hawk. The bridge was dedicated on June 17, 1929, with the governors of Iowa, Wisconsin and Minnesota present. Thebridge functioned as a toll structure until flooding washed out some of the approach spans over the Wisconsin bottoms in 1945. It stood unused for several years until the approaches were re-constructed and the bridge re-dedicated in May 1957. The Black Hawk Bridge now carries traffic as a free bridge, in essentially unaltered condition. The importance of the Black Hawk Bridge to commerce and transportation in northeastern Iowa can hardly be understated. The only highway bridge over the Mississippi River in the region at the time of its completion, the Black Hawk Bridge is historically significant for its role in the development of northeast Iowa. Although its design and dimensions fit within the mainstream of bridge technology of the time, the structure is technologically significant as an uncommon, large-scale example of cantilevered truss design. Few such cantilevered trusses were erected in Iowa, those primarily over the Mississippi or Missouri Rivers, and even fewer remain in use today. The Black Hawk Bridge is one of only five such long-span, cantilevered trusses in Iowa. [adapted from Fraser and McWilliams 1992]

Closed for a couple of weeks for deck panel replacement.
Yeah, a canal east of the bridge might be a possibility. It's all sloughs and backwater in the river bottoms.
It seems that dredging a path through Big Lake from DeSoto to Lansing could also possibly be a way they could straighten out that curve. I'd much prefer changing the course of the navigable channel to replacing the bridge.
I don't know how feasible that is though.
The barge hits must be regarded the same as "stupid trucker tricks" that have collapsed a number of historic bridges. Better training for tugboat captains is needed.
Instead, the Coast Guard should consider a short canal across Island 146 to straighten out the bend in the river for boat traffic, and build a new cheap UCEB for highway WI-82 over that canal. Most of the canal-building would simply be widening channels that already exist. (Look at Google satellite view.) This would both preserve the historic bridge, and ease river navigation for the increasingly large floatilas of barges. The total project might even cost less.
Jason, nobody would like to see this bridge saved more than me, it is one of my favorite bridges. But decisions by the Coast Guard may not be "final" but they are nevertheless about as close to "Set in Stone" as any word can be. But if you think you can convince the Coast Guard that this bridge is NOT one of the top 2 most difficult highway bridges for barge traffic to navigate (due to a bend in the river), then great! I am just relaying my assessment of this bridge's future based on my review of official project documents I have seen as a Section 106 Consulting Party. It looks pretty hopeless to me.
I hope you're right Jason.
It'd sure be great if Blackhawk could be saved. A two way couplet does nothing to widen the clear span below the bridge, however.
They want to push ever larger groups of barges around that River bend, so they want more space.
Lots of people have made lots of plans for the bridge's demise. Engineers are looking to make their mark on history and contractors and materials suppliers are looking forward to the business, motorcyclists don't like the deck, truckers and RVers don't like the narrow lanes or the option to go north or south to the next bridge in order to get to the Wisconsin River bottoms.
It's too big to be maintained just for hiking/biking or to be sold and moved to someone's farm Creek.
Sure don't want to discourage someone from saving her, but the odds are not in our favor.
A bit pessimistic, aren't we, Nathan? In my opinion, if we have eight years time between now and the time they remove the bridge, that's more than enough time to form a Group that's willing to save and maintain the bridge, which includes garnering financial support and Manpower, even on the political Level. We also have to look at the changes in the political landscape beginning with this year as well as 2024. Just because the Coast Guard says it must go, doesn't necessarily mean the decision is final. It may be that changes in policies may end up having the bridge remain as is. My point is if there is a will to save the Black Hawk Bridge, then the time to save it is now- as long as the window of opportunity is open. It has been done with the Winona Bridge, it can be done here. Nothing says there cannot be TWO bridges side-by-side. My two Cents on this.
They COULD rehab it to last another 75 years, but the WON'T. I agree with Don its a lost cause. Can it be preserved? Yes! Should it be preserved? Absolutely! Will it be preserved? Most certainly not... its very sad as this is one of the most unique bridges on the Mississippi River.
Save it? Good luck. It will be gone within 8 years.
They hope to save or reuse the west abutment and some portion, out to the first pier for an interpretive overlook or something.
I'd prefer to continue looking over the current bridge from Mt. Hosmer.

It's about 60 miles from me and one of my favorites. Hate to see it go.

Now we must save this unique bridge. If anyone ever wondered how a cantilever bridge works, one glance at this bridge shows you how.
And here are the choices:

Doomed.
New bridge construction will be underway by 2024. There will be no rehab, which would have bought her another 20 to 30 years. Bridge must be closed by 2028, and the USACE won't let her stand unused.
What a waste.

Having said this threatened bridge was one of my favorites, I figured I had to upload my own best photos of it.
Even though it crosses the state line in the middle of the river, it appears from the highway signs at its west end, that the state of Iowa considers the whole bridge to be route WI-82.
I avoid looking at these beautiful cantilevers much anymore because it feels as if they are all potentially doomed!
This one is indeed a favorite of mine as well!
Roger,
This is one of my favorite bridges too, for the same reason: its vivid and honest display of engineering. Sadly, I also learned today this bridge is in Section 106 Review and documents presented to date indicate strong leaning toward demolition and replacement. Among the deficiencies cited perhaps the most hopeless is that apparently it is considered a hazard to navigation (boats) and when the coast guard makes such condemnations the future is usually very bleak.
WI 82 has been reopened across the bottomlands approaching this bridge from the east, per https://511wi.gov/
The Black Hawk Bridge is one of my favorites, especially among Mississippi River spans. Up there with the Eads, Dubuque, both Huey Longs, and the sadly lost Savanna-Sabula bridges. How does a cantilever bridge work? Just look at the Black Hawk Bridge - it's quite obvious.
Closed due to concerns about the effects of high water on the bottomland road on Wisconsin side.
Bah. Progress sucks.
Blackhawk Bridge is perfect in this rural area.
How about they route the big trucks and RVs and motorcycles to Prairie Du Chien.
Emergency vehicles can serve their respective sides of the river. It's just lonely scenic roads through the bottoms leading to small river towns in the region anyway.
Hell, for all I care, they could even dredge a straighter channel from DeSoto to Lansing. That would remove the bend in the river to ease shipping.
Just don't take that bridge! It's been rough the last few years for my favorites list:
1. Blackhawk Bridge
2. Gilliece Bridge lost 2017
3. Wagon Wheel Bridge lost 2016
The bridge, while not officially slated for demolition, is having its replacement planned:
https://www.waukonstandard.com/articles/2017/08/16/public-le...
Blackhawk bridge has reopened after being closed due to road washout(leading to a fatal accident) on the Wisconsin side.
Its also a repainting project. Tried to rephotograph the bridge during the historic bridge weekend, but the containment wrap totally ruined my photos.
Went to the river and was surprised to see construction going on. Apparently it's just a new bumper to keep river traffic from hitting the pier.
Sorry about poor image quality.
This bridge is one of my favorites too. The views of this bridge from Mount Hosmer lookout are absolutely spectacular.
My understanding was the bridge was only closed for a day or two until inspectors checked the bridge for damage, found none, and reopened it. If anyone has heard otherwise, let me know.
The long-term risk of closure (and probably demolition afterward although nobody has used the word yet) remains with this bridge. The relatively low traffic volumes and dwindling funds may eventually mean that there is no money to replace or even repair the bridge and it could be closed permanently. If it is closed for too long, the coast guard will then order the demolition of the bridge, just like with the Bellaire Bridge. The Coast Guard has some stupid policy where they often try to say a bridge must be serving a function if it crosses navigable waters. No abandonments allowed. This fate may not be for many years, but I have read this in past news articles. Its an eventuality to be aware of.
One of my personal favorites
Does anyone know the status of this bridge? It was closed on July 22, 2010, due to a MVBC (Moron Vs. Bridge Collision), and would remain closed until further notice. I certainly hope it doesn't spell the end for this bridge, as it is one of the most unusual and beautiful cantilever truss bridges on the Mississippi.
this was the bridge used in the movie the straight story about the man on a riding lawnmower

I finally got to see this breathtaking bridge in person and got to drive across it today. The thought of demolition of this magnificent structure is appalling to me, and talking to one of the residents of Lansing, the entire village is also in an uproar about it. The businesses in the village are in some way connected to the bridge, and its loss would also mean a tragic loss for Lansing’s identity as well. Many people have appealed to the Coast Guard to consider preservation options, but the Coast Guard does not seem to care, and has given a huge “F you” to the entire village. FAIL.
