Mayor Stephanie Rawlings-Blake said a 24 hour a day, no vacation or holiday approach is what got 26th street residents back inside their homes ahead of schedule.
Most were cleared to move back in on Thursday, but the mayor said the city stayed flexible with hotel arrangements to give residents until Saturday.
"I think everyone knows that the larger construction to finish the street, prepare the wall, put up the fence, the sidewalk, all of those things, that's going to take some months but at least the residents are in their homes safe and we can continue that construction work on a regular construction schedule, not an emergency basis," Mayor Rawlings-Blake said.
That work will be going on for the next six to eight months.
Also ongoing is the process of figuring out what caused the collapse and who is responsible for what parts of the $18.6 million price tag, the city or CSX.
"We're doing our due diligence, they're doing theirs, we're taking a look at still reviewing what caused the slide and in that work we're also preparing for the negotiations with CSX," Mayor Rawlings-Blake told ABC2.
