A fifth-grade student heading to her school was struck by a vehicle and injured Wednesday morning a block from the campus in Northwest Washington, according to police and school officials.

The victim is a student at the Latin American Montessori Bilingual school in the 1300 block of Aspen Street NW. The girl was struck in the 1400 block of Aspen Street, near 16th Street.

D.C. police would confirm only that a female juvenile was struck by a vehicle shortly after 8 a.m. and was reported conscious. A fire department spokesman said that the girl was taken to a hospital in serious condition, but the school’s assistant principal said later that the victim’s condition had improved.

The crash occurred between the neighborhoods of Brightwood and Shepherd Park and next to the sprawling Walter Reed campus that is in the midst of transforming from a military hospital to a new residential community with shops and restaurants. It remains an active construction site. There also is another school nearby. Aspen Street, although residential, is often busy with children and vehicles.

Ernest Yombo, the school’s assistant principal, said the student was taken to Children’s National Medical Center. He said he walked to the scene as the ambulance was leaving with the girl. He said that most of her classmates were already at school and that it appeared the girl who was struck was running late.

In a letter emailed to parents, Yombo said the girl was with her mother when she was hit. “We are in contact with the mom to let us know how the student is doing and if there is anything we can help her in,” the letter says.
