Looks like they might use the pony truss for a pedestrian bridge:

Project Report Here: MoDOT inspection report from 2015 included with evidence of spalling roadway with exposed rebar, lead paint, section loss in the stringers and trusses. It's a big bridge and an expensive fix.

Revive66, Revive the American Road Trip, Revive the Gasconade River Bridge. This is one troll, we need lots. Help us, if you have kids.....

It's a contest! Win a Slammer BMX bike! Kids ages 2-17 are invited to create an image of a friendly troll named Grins. Our Grins has lost his home (a bridge in Iowa) and he is looking for a new home. He is traveling with his friend Cheery the Cardinal. Grins lost everything in a flood, including his mirror, so he needs YOUR help in discovering what he looks like! See contest rules here: Send your original drawings to Grins at GrinsTroll66@gmail.com. Contest starts TODAY, December 18 and ends January 3, 2018.

Julie, you can count me in for any projects up here in New England! I can think of quite a few gems that need restoration/preservation up here, and I'd be happy to team up to make sure we don't loose 'em!

If you are in the neighborhood on November 5, stop by and become a part of this project. It will take a lot if it is to be saved. We kick it off then. More information here. James Baughn, we are in your neck of the woods. We have bridge projects going in three states now. I believe if regional bridge hunters joined us we could expand and save more bridges. It is going to take more than just us and the gang, that's for sure. This is a great project for size and economic development. We need everybody to generate ideas that generate action.

FOR IMMEDIATE RELEASE Grinnell, IA - Holt, MI - Hazelgreen, MO

Please join us as we as we launch the Gasconade River Bridge Rehabilitation Project. 

The North Skunk River Greenbelt Association (NSRGA)/ Workin' Bridges has been given the green light by the Missouri Department of Transportation(MoDOT) for a conceptual agreement to begin the fundraising efforts to actually restore the Gasconade River Bridge at Hazelgreen, Missouri. A new by-pass bridge has been designed and will be constructed in 2018 which left the historic bridge at risk for demolition. The Rte 66 Gasconade River Bridge Guardians have lead the effort for preservation and MoDOT agreed to let the efforts begin to find the funding required. Let me be clear, the historic bridge is still at risk for demolition unless sufficient funding for restoration can be acquired in the next fourteen months.

The four spans of the Gasconade River Bridge include two Parker Trusses, one Pratt truss and a Warren Pony Truss, built in 1923 and designed by MoDOT engineers. A current engineering estimate by MoDOT estimated repair work at over $3 million dollars. The Workin' Bridges qualified engineers and craftsmen will assess the bridge for possible phased options and costs that may differ from MoDOTs assessment. These real numbers, captured as Scope of Work and Estimates are required so that informed decisions can be made, for potential grants. Work with MoDOT on a risk management plan for their new bridge and the Interstate 44 bridge is being negotiated. We have proposed a Trust Account that would be in place for a catastrophic event, as well as utilizing the interest for future biannual inspections and site and security.

Developers are also being sought for this property and any design ideas are welcome. Route 66 has always been a mecca for travelers worldwide and with this bridge repaired the potential for crossing on special event days may still be an option as engineering will return the bridge to its former function. For more information on how the bridge was saved and how we are moving forward together check out Workin' Bridges: Route 66 Bridge Rehab on Facebook

Our goal is to raise $10,000 in funds. Those funds are for engineering and planning. Jacqueline (Jax) Welborn has been designated the Project Manager. She will undertake the outreach for donors to help with the immediate engineering and planning needs for the bridge. Contact Jax at rte66bridgerehab@gmail.com or call her at 573-528-1292.

Then our efforts will turn to finding the pledges, grants and in-kind donations necessary to reach our $3.5 million dollar goal by December 31, 2018. That money will go to repairing the piers and abutments that hold the spans up, the stringer and roadway replacement, floor beam repair. The deck, or at least a portion of the deck will be removed by MoDOT using their demolition funds for that purpose. The lead paint abatement solution is still to be determined.

Those efforts are currently underway. NSRGA has begun the process to become a legitimate nonprofit corporation in Missouri, then the bank accounts will be procured. In the meantime you can still donate at Workin' Bridges: Route 66 Bridge Rehab on Facebook. Your donations are tax deductible to the fullest extent allowed by law.

Other questions, please contact Julie Bowers at jbowerz1@gmail.com or 641-260-1262. Check out this project and others on Facebook at Workin' Bridges, www.workinbridges.org and become a Save Our Bridge (SOB) action figure today.

I visited this bridge on January 28th. I just happened to be passing through the area and spotted it. Fearing the bridge's future I decided to take some pictures even though it was getting dark. I didn't get any pictures of the West side of the bridge as it was getting dark too quickly. This bridge does not appear to have had a complete road surface replacement for quite some time. Once again it looks like a little routine maintenance would have gone a long way. Hopefully the bridge will be repaired or at least preserved in-place.

Laclede County Bridge Closed Indefinitely

JEFFERSON CITY - The Missouri Department of Transportation has closed the bridge over the Gasconade River along the Interstate 44 outer road in Laclede County after a recent inspection determined the bridge was unsafe for travel. The bridge will remain closed until further notice.

"We found enough issues with the 90-year-old bridge to decide the safest thing to do was to close it to travel," said MoDOT Central District Bridge Engineer Alan Trampe.

Added MoDOT's Central District Engineer David Silvester: "One of the big concerns with closing this bridge is that it's located on the route we use to detour traffic off of I-44 when there's an incident. We'll work over the next few weeks to determine what repairs need to be made to reopen the bridge, if that's even possible."

The majority of the state's bridges are routinely inspected in late fall and winter. The average Missouri bridge is 46 years old, but most were designed for a 50-year life.

A complete list of unplanned bridge closures throughout the state can be found on MoDOT's website at http://www.modot.org/. Included on the page are inspection photos, the reason for the bridge closure, corrective actions to be taken and how they will be paid for, a map of the bridge location and recommended detours by way of state highways.

"With the large number of bridges we have in Missouri, all of which are aging every day, and with our construction budget continuing to decline, it's likely we will see more closures in the future," Silvester said.
