Just after 11 p.m. on April 28, Mrs. Grossman, 63, got off of a bus on Georgia Avenue near Rippling Brook Lane in the Aspen Hill area.
As she tried to cross the six-lane road, she was hit by the driver of a Toyota Camry.
She died of her injuries.
Mrs. Grossman was struck just about two blocks from where her husband was killed in a similar crash in October of 2016.
Mr. Grossman was 64 at the time.
Councilmember Nancy Navarro, who represents the area where the deaths occurred, said change is desperately needed.
"We know that that particular area of Aspen Hill has been real problematic," Navarro said. "We have worked with the State Highway Administration because it is the state road."
