Good detail in this article: https://www.constructionequipmentguide. ... ject/45396
In Connecticut, pre-construction efforts are under way on The Walk Bridge Replacement Project. The project is currently at 60 percent design, and is expected to start construction by summer of next year.
"This includes demolition of the IMAX theater, and relocation of the railroad power lines underground. In year two, we remove the existing high towers and construct the lift towers for the new Walk Bridge. We will start the construction of the southerly two tracks. While the southern tracks are out of service, work will begin on the concurrent Fort Point Street, East Avenue and Osborne Avenue railroad bridge replacement projects. During the third year of construction, we will complete the Walk Bridge's southern half approaches.

"The southern lift span will be built off-site using approximately three million pounds of steel and 45,000 bolts. The span will be floated-in and installed over an extended weekend while the existing swing span [all four tracks] is simultaneously removed and floated north for demolition. The Program would then open the two new southern tracks and begin work on the northern half of the bridge. This work will mirror the southern half and extends into year 4/5. The completion of the northern and southern halves of the bridges at Fort Point Street, East Avenue, and Osborne Avenue will occur simultaneously, to coincide with track outages for the Walk Bridge."
Next stop, Willoughby

I certainly hope the "off site" span construction is occurring "up river" (north, as in wherever they are floating the existing span for demo). Doesn't seem like a good plan to install the SOUTH span first if you then have to "float" the north span through it in order to install it.
GE, not EMD, makes the best locomotives now; has for over 20 years. Get over it.

Construction will occur on a barge about 1/4 mile south of the current bridge. The barge will be moored adjacent to two open lots along Water Street on the west bank of the Norwalk River.
