More from the Loose Ends Never Ends files. I have about 500 more negatives to scan in this one collection. Just finished up more of the Liberty Dam and adjacent bridges. I must confess, I have never really done a lot of research concerning these bridges. Over the years I have found hundreds of photographs/negatives, and only found a few of them interesting; like Liberty Lumber, the Indian grave marker and the dam itself. Although I really like climbing on and under bridges, I never gave these photos much thought. Looking at Google Maps, it is hard to place the original/present location of these bridges. I’m just not familiar with the area’s history. Most are from the early 1950s.
Ivy Mill Bridge is first. I like this one because it shows the old structure in the background. This photo is one of the few with a description attached.
Beginning construction, temporary bridges were built.
Foundation and columns poured.
As can be seen, these photos are missing the contractor’s descriptions of work – black rectangular areas on photos.
Moving right along with progress.
Reaching the final height and then comes the decking.
The finished bridge.
Next collection of negatives were marked as North Branch Over Patapsco, including Morgan Run. General view of the area.
Setting forms for foundations.
Columns.
Ready to place decking.
Putting on final touches.
Finished bridge from old bridge. (I wonder if this old one is underwater?)
The next group I found were of the Snowden Creek Bridge. Not many photos in this collection. It must be way up there because it looks pretty shallow. Forms poured and ready for decking.
Near completion. 
The next 500+ negatives to document are of building the Susquehanna Tunnel.
Here is the photo of the grave marker, taken from an engineer’s scrapbook.
