Hayes Street Bridge is 20 feet wide curb to curb. Should be wide for most Amish traffic. Wide enough for two buggies to pass, anyway.
As fmiser previously said, widening would require longer floor beams and wider deck surface, so more weight and modern I-beams, but if the trusses are restored to the 1992 inspection quality, it will still carry a lot.
1992 Operating rating was 43.6 tons.
SW Howard county has a Mennonite produce auction that is on a road that was served by a pony truss that got damaged, removed, and never replaced. The only other route to the auction is a Mitchell/Howard county road that has a steel wheel ban.
I bet they'd love to find a bridge like this. (And county officials willing to approve the work)
We are only bidding on replacing the photographed panels on each corner due to section loss. Just wondering, this is pretty beefy, widening by putting in new floor beams to x feet would be an interesting number to run....engineers?
Otherwise it will be restored with in-kind restoration; rivets with rivets. The county will do all the work except for the repairs which they are letting us run numbers on.
More will be revealed.
Yes strictly one lane 17 ton just no wide heavy farm equipment. They have other roads to go on and there is only one non-Amish farm to the south and west of the location.
Fun to see the Amish Auction going on and to hear the engineer talk about shoulders and what works best for horses and a variety of vehicles behind them.
It would be extremely difficult to widen any truss bridge and retain any historic integrity or original functionality...the only option available would probably be to put in a new slab and place the trusses as decoration, which to me isn't much of a solution... It seems that they want to keep the traffic to a minimum anyway if its passing thru an Amish community, both for the integrity of the Amish community itself as well as for the safety of the residents... I think the best solution is to restore the truss to completely original specs and reinstall with posted load limit.
This will be the place where the Hayes Street Bridge, a 1925 Warren pony truss will move if approved. Wonder if it is strong enough to go wider to serve everyone. Hmmm.
Not sure what ever came of this one, but the current pinned location shows a culvert and fill..
