Why bother with yet another overpass that is a long ways from Chicagoland? Because this 11' clearance bridge is being replaced with a 3-track, 14' clearance bridge and I wanted to get some "before" pictures.
"The biggest challenge on any bridge replacement project is to minimize the impacts to the customers and public," said LIRR spokeswoman Sarah Armaghan via email.
To overcome that obstacle, LIRR removed the existing structure and installed the new one during a single weekend track outage in late October. The railroad also kept the public informed of the project through fliers, radio ads and social media posts, Armaghan said.

It would be relatively easy to build the replacement bridge off site and then move both bridges during a weekend. We have already seen
a large truss span constructed out of the way and then moved into place. But that minimizes the impact on the railroad customers. I'll be the users of the road were impacted for many months as they dug out another 3' of clearance. But zooming out on the satellite image, I see that there were other roads realatively nearby. So I presume the impact on traffic should not have been as bad as the
25th Avenue grade separation in Bellwood, IL. Not only was the road out for a couple of years, the other major artery through the area, US-45, was already congested.
