Why didn't they raise it in one shot? Or did some bigwig decide it was still too low even after being raised just months ago?
Road sits atop a very large storm drainage culvert and cant be lowered. What it is now is what it will remain.
tree68Undercutting the road will cascade out to other streets in the area. It might be possible to jack the bridge - it depends on the profile of the tracks on either side. If the bridge is a low spot, then some stone will be all that's needed after the bridge is raised. Otherwise, they may find the same problem that's keeping the low-clearance bridge in Syracuse/Liverpool, NY from being raised - it would make the grade coming off the wye just too much. The road there can't be lowered - it's built on an old canal and is right next to Onondaga Lake. Flooding would replace the low bridge as the hazard.

The bridge could, relatively easily, be jacked up to clear 13'6" trucks - raising the adjoining rail lines so as not to create a helper district and/or train handling disaster is the problem.
I don't know if the road is subject to flooding at its present elevation

Here's the unembedded 'raising' video:

This whole article from the OP is almost a year old. It was raised in 2019 8", but its not being raised again.

NS Raised the bridge 8" on 10/29/2019 ... so far 4 trucks have hit the raised span.

Is the bridge actually going to be raised 8 inches or is the roadway going to be 'undercut' 8 inches.
I can't see NS being able to raise the bridges and its approaches 8 inches for only $500K. I can, however, see the roadway being lowered 8 inches for that amount of money.
I last stayed at a Holiday Inn a decade ago.
All the way up to 12 feet four inches: https://jalopnik.com/north-carolinas-infamous-low-ass-bridge-will-soon-be-ra-1839237006
Trucks, however, are still allowed to be 13 feet 6 inches high
