• Dock Bridge - Passaic River

  • This forum will be for issues that don't belong specifically to one NYC area transit agency, but several. For instance, intra-MTA proposals or MTA-wide issues, which may involve both Metro-North Railroad (MNRR) and the Long Island Railroad (LIRR). Other intra-agency examples: through running such as the now discontinued MNRR-NJT Meadowlands special. Topics which only concern one operating agency should remain in their respective forums.

Does this mean the bridge is being closed for good, or just that it will get a more reliable technology less likely to fail when the bridge is opened and closed.?

Sounds like it will be closed for good, unless you want to open it and tear out a bunch of welded rail.

Does this quote mean Dock will no longer open?

Yes. To confirm, can go to the NEC Commission website, then to the document library and download the Appendix to the NEC Capital Investment Plan (FY 2023-2027). On the page for the Dock Bridge project in the general information section, it states:
"The Highline Renewal and State of Good Repair for Dock Bridge includes several enhancements and modifications: structural steel painting (the largest portion of the proposed scope; will remove original, failed lead paint that is contributing to corrosion of the bridge), steel repairs, modifications to convert the bridge to a fixed bridge, installation of straight rail to replace movable miter rails, new aesthetic lighting to increase civic presence, fender replacement, concrete pier repairs, and the associated installation of a targeted cathodic protection system designed to slow or stop the corrosion process of the bridge’s concrete supports. This work will prolong the life of the bridge and minimize the risk of more costly rehabilitation in the future."
So Amtrak (and NJ Transit) will have 1 less moveable bridge to deal with on the NEC.

All interested parties are notified that the Commander, First Coast Guard District, has received an

fixed bridge over a navigable waterway of the United States." https://navcen.uscg.gov/sites/default/f ... ver_NJ.pdf

What sort of marine traffic goes through here and how often? Must not be anything big if current levels allow for the bridge to be locked in place.

Practically nothing? We opened it for something in the winter of 2019(?) after the interlocking was remoted to PSCC in late 2017. Hell, PATH didn't even have to lift their span. We only moved the 1 and 2,3,4 spans.

THanks everyone for clearing up the issue of it DOCK will really become a fixed span.
I remember some posts years ago about how often they would have to open Dock to barge out the spoils from dredging upstream on the Passaic River to get all the PCB's or whatever out of the river bottom. Either that is all done, or they will truck them out instead of barges I suppose. Or use barges & tugs that only require a very low vertical clearance.

Dock Bridge Rehabilitation | Amtrak - lots of details.
"Final Design; construction is anticipated to begin in 2024."

Dock Bridge - Wikipedia
The lower 17 miles (27 km) downstream of the 90-mile (140 km) long Passaic River below the Dundee Dam is tidally influenced and navigable.[3] When closed the bridge has a vertical clearance of 24 feet (7.3 m) above mean high water and opens to clear 135 ft (41 m).[8] It is infrequently lifted and, prior to 2014,[9] had not received a request for a river traffic opening since 2004.[8] In 2011 regulations were changed so that it need not be open on demand (as it previously had[10]) but with a 24-hour notice.[11] During four-year removal of dredged materials from the Passaic the bridge is expected to open upwards of 10 times per day.[12] In 2020 Amtrak requested that bridge remain in closed position until such time as it can be rehabilitated.[13]
So making that bridge a fixed one won't be much of a loss.

Lotta signal revisions involved with converting it to a fixed span. Need to remove all the RBR or NBR relay logic in the vital microloks. Get rid of the GEK! I think this one was designed with the NBK being energized when lined for rail traffic, while Portal had the RBK up for rail traffic.
