Northern Avenue will be partially shut down starting Dec. 8, so a dormant railroad track can be removed and rough pavement can be fixed, city officials said.
The work is not expected to take more than a week, weather permitting, officials said.
Half of the road will be closed at a time so traffic can pass, said Assistant City Engineer Rodney Tissue.
CSX Corp. will remove the western track and repave the area, he said. CSX will pay for the work.
The entire road is expected to be shut down for about two days next July as CSX replaces the entire railroad crossing, Tissue said.
The Maryland State Highway Administration will pay CSX $150,000 for the work, which will include replacing the nearby sidewalks, he said.
