Residents near Baltimore-Washington International Thurgood Marshall Airport may soon start seeing large, white X's on streets in their communities.
About 40 of the markings will be painted on public rights-of-way around the airport within the next few days, airport spokesman Jonathan Dean said in a statement Friday.
The airport is updating its mapping database, he said, and aerial photographs will be taken as part of the project. The Xs help improve the accuracy of the photographs.
The markings are temporary and will be removed after the photography is complete, Dean said.
