This a longstanding issue. The Howe Street/River Street bridge has been condemned for several years; the County first put a one-lane restriction on it, then set a 22 ton limit (the rationale was that Jones' trucks were only on the bridge a few axles at a time). Its replacement has been in the works for years. Going out to County 1 would have to be done on the east side of the old yards (the west side wouldn't work because of the creek and wetlands). That route would require a grade crossing over the main and run-around track; as I understand it, at the County 1 end it would require the acquisition of a small sliver of land, that the owner is not willing to sell.
The current temporary workaround is another crossing near the Wawayanda bridge (19.9) connecting to the dead end of Orchard Street. Trucks would use that, Hamilton Avenue and Campbell Road to access Oakland Avenue (Rt. 94/17A). Not surprisingly there has been some vocal NIMBY opposition, but apparently its a done deal.
Permanent solution (as of the latest, anyway) is a replacement bridge, either at the current location, or adjacent to it.
