Would somebody mind pasting the 3 files together to make a single map? I'd like to see the entire interchange, but my Photoshop skills are lacking.

I've done some Photoshop stitching in the past so this wasn't much of a problem for me although I did have to use screen captures to convert the PDFs into PNGs and JPGs.

If you import the PDF page into an Inkscape document, it will drop the original raster images as PNG (or maybe JPEG as appropriate?) files on your hard drive so the SVG has something to link to. I think they usually go in the same folder as the SVG doc, but if you haven't saved it yet (for example, it's a blank drawing you just created to import the PDF) they could end up in Inkscape's program folder or somewhere else dumb.

Another approach is to use a paid version of Adobe Acrobat, which will convert .pdf files into some other format that can be edited (or stitched together) in Photoshop or other image editor. I'm not sure that yields better results than the other ways, plus you need to pay Adobe or lean on someone like me (when I become available for that next week) who already has a copy.

There are free tools that will dump raster images out of PDF files.  I use pdfimages (part of the xpdf utilities distribution), which is one such tool, in conjunction with ImageMagick for post-processing (by default pdfimages will output images in oddball formats, which ImageMagick understands but which some cheap image browsers don't necessarily support, so conversion is sometimes necessary), as well as the tifflib distribution to ensure ImageMagick can handle Group IV monochrome TIFFs.  I also have GhostScript installed to force version downgrades for recalcitrant PDFs.

The main disadvantage of this approach is that it requires familiarity and comfort with the command line, as well as editing the Windows %path% variable so it can find the relevant executables when they are invoked at the prompt.
