Bridge Load Limit

[fried1765]

But to be fair, I would expect that. They design bridges for a safety factor of two or more.

He would cringe if he saw some of the bridges we have hauled 100,000 pound loads of logs over, but as I said in my first post, it is not often you have a bridge so long that the whole truck is on the bridge at once.

Here is a fun fact though: Maine had the first weight limits for trucks.

My Civil engineering RPE former roommate lives in Winthrop, Me. and is retired from the Maine DOT.
After nearly 60 years, we still talk by phone.
A really great "Mainiac" guy talking with his "Masshole" classmate.

He probably knows my ex-father-in-law, he worked for the MeDOT all his life as a surveyor. He is long since retired, and I lost track of him when I got divorced from his daughter.

He was telling me, back in the 1980's, he had to scale Mt Katadin because the State wanted to survey a road to the top. He said it was stupid because anyone knows, when Governor Baxter gave the state the land for that park, it specifically states, "No Motor Vehicles" so they would never build a road to the top. Still, somewhere, they have a map of a road on how to get to the top.

But he was interesting. When I fist met him...the very first time, he did his research on me and said, "Oh yes, the BrokenTrack family, you sold 100,000 yards of gravel to the MeDOT in 1969, at 10 cents a cubic yard, with you grandfather loading the gravel with his tractor..." It was all true. I have since tried to find that report so I could see what the Maine Geological Society had for information on the pit, but it seems no one but him could find the report.

I would certainly assume that he would know your ex-father-in-law
I believe that Brian may have actually started with ME DOT as a surveyor in 1961.

Well Gents,
A fellow TBN'r helped me with the information I needed.
Many Many "Thanks" to him and his team.

MY decision is to reduce loads to a tandem axle truck to
keep all parties agreeable to the suggested weight capacity of
the bridge.

Nice of you to post information on the final result. Many do not

What's funny is if you've ever seen some of the 'temporary logging bridges' in this country that fully loaded trucks cross yours looks like the Golden gate. But, at the end f the day, it's the driver who pays the price. Saying "but he said it was good" doesn't cut it with the boss or the insurance company. Glad you've found a compromise everyone can live with.

A friend of mine in Canada, was driving a log truck over just such a bridge, and the bridge failed.
Took nearly 5 years, and lots of attorney (barrister there) dollars to finalize the case.

When I was a teenager in Ohio, the historical covered bridges were open for vehicle traffic, but normally had a weight limit of 5 tons for them. One day there was a picture in the paper of a fully loaded dump truck that had fallen thru the floor of the covered bridge. I don't remember what the outcome of that was but I can guess.
