If this was a thing that happened, It'd probably be a good idea to extend it the extra .5 mile to just south of the rail ROW to allow for a transfer to the Rush Line for those heading further north. 2 miles and 4 stations shouldn't cost too much. The short bridge over 94 and retrofitting/replacing the 7th St Bridge (or building a new small one adjacent to it) would probably be the most costly portions of it.Do any of you see major barriers or benefits to extending the Riverview corridor up East 7th to around Arcade Street? This would encompass the proposed first line of a St. Paul streetcar network. It would hit Metro State, which is just out of reach of the Gateway Corridor and might not be the route choice of the Rush Line.
It would add about 1.5 miles depending on the route.
On another note, I recall there being a note from the St Paul streetcar study website:
"The City has completed work on the Streetcar Feasibility Study at this time. The City Council's resolution supporting the results of this study also directed that the Starter Line not be studied in more depth until the Ramsey County-led Riverview Corridor Study has made a recommendation."
Given what we know about the likely outcomes for the Riverview and Rush lines at this point, what might St Paul do with their streetcar study? Build a link similar to what Vagueperson mentioned, from Lowertown up E 7th St (which would overlap with the route 54 extension)? Maybe a new starter line on Payne Ave or Grand or something?
