Arlington Memorial Bridge

Another thought.

The 1986 "rehabilitation" was likely when the machinery to open the bridge was disabled. An interesting use of the word rehabilitation, don't you think?

I read the Washington Post story and now understand why such strange language is used. Editing is a lost art in todays news papers. The author said "inoperable" when 'non-operated' or unoperated would have been more correct. So sometime following the closure of the Potomac to high profile craft, the draw bridge was rendered inoperable.

Sloppy writing.

Ed, I am not the author of the language you are referencing. However I can confirm per the bridge inspection report that "The bridge is currently “locked” in the closed position and all of the electrical equipment has been dismantled." This includes bracing beams added underneath the counterweight. Operating the bridge would require removal of the bracing, and installation of new electrical (and maybe some mechanical) equipment. That said, the key features of this bridge which convey the Strauss design remain intact and these include: riveted truss leaves, Strauss' patented layout of trunnions and links for each leaf, and concrete counterweights. The photo here from the inspection report shows the counterweight bracing. All of this material has been released to the public as part of the replacement contract advertisement.

Would like to know why the bridge is inoperable but other bridges being too low is not the reason why this draw bridge is inoperable. It is why it is unneeded, why it stopped being operated but if it's inoperable than needs to be some mechanical or structural reason why it can't operate.

The fact that it hasen't needed to operate does not make it inoperable.

To clarify the nature of the project, this now-awarded Design Build project (which has been discussed with little public consultation) involves the total demolition of the structural elements of the main bascule span... in short, complete loss of all structural elements that convey the bridge's patented Strauss trunnion bascule design. Only the decorative non-structural cladding from the bascule span will remain following the project. The riveted steel trusses which include v-lacing (and can be seen by anyone on a boat going under the bridge including tour boats), the double-trunnion bascule system (which remained in place despite the disuse) will be lost. The replacement structure is a fixed girder structure of completely different design. While the appearance of this bridge will remain similar (except for loss of riveted trusses) following the project, we should still be disappointed in the total loss of one of the finest and most significant Strauss bascule bridges in existence.

Department of the Interior announces contract to repair bridge. This will replace the Strauss bascule span with a similar-looking fixed steel span. It hasn't been opened for a boat since 1961.

I am disappointed that the drawbridge doesn't function anymore. When the very old bridge had its final operation in the 1960's, this drawbridge will no longer open. But the drawbridge didn't had a traffic light or gates. I hope this bridge gets rebuilt as a replacement drawbridge.

Found this blog post with a photo of this bridge being built - just the formwork was up.
