I believe they are just to minimize the number of vehicles on the bridge at any
given time. There are signals at both approaches.

Nice. Can't believe I've never made it to this bridge... definitely one
of the lesser known "under appreciated" bridges of the few 100+ year-old suspension bridges remaining in the U.S.
Sorry, I'm not going to be of any help there. Those several "high shots" within the slide show are as a result of my climbing up the structure. My wife has accompanied me on less than 1% of my 1,053 bridge visits. I may even be able to count them on one hand, thus about half that 1%. I can't even even get her to take those pictures of me holding my counter, even when I could get her out on the bridge. The intensity of my trips makes these solo efforts. Example: Taking a nap prior to leaving home at 11PM for a 6 hour drive to be at the first bridge at sunrise such was done with the Keeseville, then going non-stop until 9PM that evening was the first day (OK, first 22 hours). The the next couple of days were from 5AM until 9PM as to use the available daylight that time of year.

The wife & I go almost everywhere together. She is also very reluctant to walk out onto a suspension bridge & I am sure I would not get away with climbing the towers.
But your high shots have given me an idea. I am going to try setting the camera self-timer & then hold it up with a monopod.

Wow. I didn't know the use of recycled plastic had caught on like that. We have
a little bridge on a sand road in the woods that is made of recycled plastic
lumber. It replaced an older one made of wood. We actually went to see it while
the worker(s) was/were still building it. I got to take home a sample of the
plastic lumber. This was maybe 5 years ago, I'd guess.
Thanks,
Barry, in New Jersey

I am going through a lot of my "unprocessed" incoming bridgemeister.com email
from the last year and once again noticing that I get MANY questions asking for
help finding contractors to build short-span (usually < 150 feet) suspension
footbridges in the U.S.
Any suggestions from this group on where to direct such inquiries?
Any websites that aggregate such information?
In the past, I had referred some requests to Sahale (http://sahale.com, closed
in 2010) and I see now they have branched off to Seattle Bridge
(http://seattlebridgebuilders.com). Any other suggestions?
Thanks,

David, in 2010 I built a 76' suspension bridge on my property. It is more than a foot bridge but far less than an auto bridge. Here is a link to the Instructables site where I describe the bridge. If you like, send me some of the references, or send my link to them. I am not sure I want to be a contractor, but, who knows?

Fort Steuben Bridge Demolition Begins
Part of span to be made an observation deck
January 12, 2012
By WARREN SCOTT - For The Intelligencer , The Intelligencer / Wheeling
News-Register
Passersby on Ohio 7 or the Veterans Memorial Bridge may have noticed sparks
flying from the older Fort Steuben Bridge and heavy equipment parked on it.
That's because crews with the Joseph B. Fay Co. of Russellton, Pa., have begun
demolishing the 82-year-old span, which was closed in January 2009 by officials
with the Ohio Department of Transportation, who said it had become too costly to
repair and upgrade to meet current traffic conditions...

Why was this bridge allowed to decay?

Bath Chronicle
By Kirsten Elliott
Bath and North East Somerset Council says that one challenge it faces at
Victoria Bridge is that it is a "very old structure", as if that is in some way
an excuse for its present sorry state.
The railway line from Paddington to Bristol runs happily over bridges of similar
vintage, and there are even older bridges and aqueducts on our canal system.
Unlike this one, they have been properly maintained.
There seems little doubt that B&NES thought that Crest Nicholson would ride to
the rescue of the bridge. Early documents promised that as a "key component of
this landmark contemporary scheme" there would be "two new bridges and the
restoration of the listed Victoria Bridge"...
I have a question, as I am not an engineer and just enjoy bridges for their general beauty (I hate UCEB and Box Girder Bridges). I don't understand a response I got from ODOT regarding the replacement of the Jeremiah Morrow Bridge. I noticed early in 2011 there was construction going on at the bridge, it didn't take too long to ascertain they were doing a replacement. So I immediately went to the ODOT website to see what they were doing and much to my dismay I found the replacement was going to be a cantilevered hollow box girder bridge. So I posed the question to ODOT why they were not replacing the Morrow Bridge with a suspension or cable stayed span because it's only 1/2 a mile from apron to apron on the bridge right now and a span like this would keep the valley floor from being "cluttered" with columns. The Little Miami River Valley is very picturesque and is done a disservice with this bridge going over it. But anyhow the ODOT rep responded saying "They don't do Suspension spans for that distance and that they are limiting the number of columns to keep things 'beautiful'". Yea they are limiting it to about 5 columns and 1 single bridge instead of the parallel decktruss bridges it currently is but is 1/2 a mile really that difficult for a suspension or cable stayed bridge on an interstate highway, especially when it can be anchored right into the valley walls?

I'm surprised they didn't come right out and say "it's about the money." Box girders are a heck of a lot cheaper than suspension spans.

It is obvious to me it's simply a matter of cost. My quick research of the Jeremiah Morrow Bridge tells me that it's a $88.1 million dollar project for 2,240 feet of bridge. Close to me down in Delaware they're nearing completion of the Indian River Inlet Bridge - a cable-stayed bridge that is $150 million and a bit longer at 2,600 feet in total length. The cable-stayed portion is just 1,750 feet of which 950 feet is the mainspan and the remainder divided equally among the two side spans. Your Jeremiah Morrow Bridge is considerably wider than the Indian River Inlet Bridge in that it's going to be striped for three lanes each direction with wide shoulders with the intention that someday it will be four lanes each direction with narrow shoulders. The IRIB will have two lanes each direction with typical shoulders and a single bicycle / pedestrian lane on the one side. Perhaps the width of the JMB makes up for the length of the IRIB. I would estimate a 2,240' suspended span with eight lanes would cost in excess of a half billion dollars.

--Steuben--Bridge--blast.html?nav=5010
February 1, 2012
By WARREN SCOTT - Staff writer (wscott@....) , The Herald-Star
STEUBENVILLE - The Ohio Department of Transportation has announced the date for
an explosive blast that will bring down the Fort Steuben Bridge.
Becky Giauque, spokeswoman for ODOT, said the blast will occur on Feb. 20 "as
close to daylight as possible" and more details, including its affect on
traffic, will be announced at a later date...
The railroad has been planning to replace the Portage trestle for years and it
would obviously be easy for them to build a newer, parallel span 100 feet
upstream of the old trestle so the famous view of the older crossing would
remain intact as well as retaining the Northern view of the gorge if the old
trestle was used for pedestrians.
With a total length of just 819 feet, this would not be a very costly walkway to
build onto the old railway deck and tourism would more then make up for it.
I should also note the original 1852 timber trestle was the highest bridge in
North America at 236 feet until it was just barely edged out in 1855 by the
famous 240 foot high Roebling Railway Bridge at Niagara Falls.
No other conventional trestle-type bridge came along that was higher then
Portage (or its 1875 steel replacement) until 1877 when the 266 foot High
Bridge in Kentucky was completed. In 1882 Kinzua finally surpassed them both at
301 feet along with two more in 1883 that were a little higher at 240 feet at
Stony Brook Glen in New York and the Michigan Central Railway Bridge at Niagara
Falls. In 1885 Canada's Stoney Creek Bridge also joined the list of North
America's highest at 296 feet.
By 1900 the following were North America's 12 Highest Bridges - all for
railways. In 1897 the Grand Trunk arch had replaced Roebling's railway
suspension bridge. Several of the timber trestles were rebuilt with steel such
as Portage in 1875.
1. Pecos - 322 feet - 1892
1. Kinzua - 301 feet - 1882
2. Stoney Creek - 296 feet - 1885
3. High Bridge - 266 feet - 1877
4. Stony Brook Glen - 240 feet - 1883
5. Grand Trunk Arch Niagara - 240 feet - 1897
6. Michigan Central Niagara - 240 feet - 1883
7. Portage - 236 feet - 1852
8. Young's High - 235 feet - 1889
9. Marent Gulch - 226 feet - 1883
10. Canyon Diablo - 222 feet - 1882
11. Poughkeepsie - 220 feet - 1888
12. Two Medicine - 214 feet - 1892
For those who are interested, these were the World's 12 Highest Bridges in 1900
- most for railways.
1. Charles Albert - 482 feet - 1839
2. Santa Guistina - 460 feet - 1890
3. Garabit - 407 feet - 1884
4. Chatelet - 354 feet - 1882
5. Mungstener - 351 feet - 1897
6. Loa Viaduct - 336 feet - 1888
7. Pecos - 322 feet - 1892
8. Malleco - 308 feet - 1890
9. Kinzua - 301 feet - 1882
10. Tardes - 300 feet - 1884
11. Stoney Creek - 296 feet - 1885
12. Ponsonnas - 295 feet - 1863
13. Puente Nuevo - 295 feet - 1751

Thanks Eric. Interesting info on the historical lists of highest bridges. I was
expecting to see the Cascade Bridge (NY) on one of these lists but apparently it
was a little "short" of these heights.

Hi Everyone,
I am putting together a picture book on the Washington & Old Dominion Railroad
of northern Virginia. I would like to include a picture or two showing how
bridges were manufactured.
The Great Falls & Old Dominion Railway became a part of the W&OD. The GF&OD had
a 400 plus foot long steel lattice work trestle just east of the National Park
Service's Great Falls (Virginia) park that was built in 1906. The structural
members of this trestle consisted of columns and beams made up of angle bars and
short pieces of flat steel riveted to the angle bars. Are there any pictures
showing how these beams and columns were built in their manufacturing plant? I
am assuming that most of the work on these would have been done before they were
erected on the bridge site. I would like to show the labor involved.

Hi All,
I added a picture of the steel trestle I mentioned in my previous message to the
Miscellaneous folder.

structural members of this trestle consisted of columns and beams made up of
angle bars and short pieces of flat steel riveted to the angle bars. Are there
any pictures showing how these beams and columns were built in their
manufacturing plant? I am assuming that most of the work on these would have
