Talk:Pennsylvania Route 23

Eastern Terminus
Google Maps, local.live.com and Mapquest all have the bit of Conshohoken Ave. between US1 and Belmont Ave. marked as 23 (zoom all the way in). Yahoo maps apears to be using the same map engine as Google. If you look at topozone.com, part of Belmont Ave. is marked as 23 as well. The topozone marking for 23 along Belmont is in purple, indicating a "recent" addition. However, this PennDoT map (LARGE PDF) draws that road section as a "City Street" (grey), not state (red). You'd think the latter would be authoritative ... . I don't quite live close enough to drive down and look at signage on the ground, as it were, maybe there's still a "23 End" sign. --J Clear 00:13, 8 May 2007 (UTC)
 * They are not reliable enough sources. One of the external links at the bottom links to state-ends.com; it has pictures of the eastern terminus.  At this stage, pictures and the PennDOT sources are your best bet.  City Streets are not state highways, due to the fact that it is not signed with a quadrant route marker or a PA Route shield.  Anything that is marked as a state highway west of US 1 is PA 23.  I can confirm this personally because I live about five minutes away from this place.

 * Yep, it ends at US 1: source No routes marked on Conshohocken Ave and Belmont Ave. -- — J A 10  Talk • Contribs 20:34, 6 November 2007 (UTC)

There are some state routes that are posted within Philadelphia. I can think of 3,63,73,291,309,611, with 309 and 611 keeping old US route numbers. (And what route number is found on Bustleton Avenue?) 23, however, does terminate right at US 1, which is there running on the Philadelphia border. Carlm0404 (talk) 21:01, 8 April 2021 (UTC)

By the way, US 422 used to enter Philadelphia on Germantown Avenue, but now continues on freeway from Pottstown and ends at King of Prussia, and is gone from Philadelphia. Long ago, PA 43 ran on the Schuylkill Expressway, which after a few iterations is now part of I-76. Carlm0404 (talk) 21:08, 8 April 2021 (UTC)

at US 30 just east of Lancaster
Notice that eastbound 23 turns onto brief wrong-way concurrency with US 30. At the point of that turn, we'd see a stub straight ahead, and I just learned that this was to be the start of what is now Goat Path because the road that was to go there was never built.

I have just followed 23 in the opposite direction in that area. Carlm0404 (talk) 20:58, 8 April 2021 (UTC)
