That gives us a bracket of ~1400 feet on either end of Summerhill, basically. <br></div><div>Measuring 7285ish feet from the South Fork/Croyle boundary doesn't yield a 700 foot window across either boundary. Measuring from a point approximately where the line rejoined the road at the east end of the diversion into the hollow where the route 219 interchange is yields a crossing in Summerhill and another in Croyle, on either side of the first underpass east of Summerhill. Maybe, but 1) the val map showing that underpass will probably tell us and 2) I don't see why. <br></div><div><br></div><div>Okay, so what if we measure from Main and Railroad Sts? Then we get a point in Croyle, east of the cemetery, and a point in Summerhill, after the line crosses the river. It would mean the line would cross the river on the north side of the street, between the street and the railroad. I don't know *why* this would be desirable, but the aerial shows something which might fit this conclusion. I'll mark up a copy and attach it.</div><div><br></div><div>Also, the answer to why the first two underpasses east of Summerhill were fine and the subway in question was not? The first 2 are multi-arch spans of ample width and the 3rd is an underpass which spanned only the portage railroad, thus narrower. Hence presumably why the state was more proprietary about it, tho it's unclear what the PRR granting use of right of way to the trolley company bought them if then they couldn't use this.<br></div></div><br>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">Daria Phoebe Brashear<br></div><div>AuriStor, Inc<br></div><div><a href="http://dariaphoebe.com" target="_blank">dariaphoebe.com</a><br><br></div></div></div></div></div></div>
