A woman may have broken both her ankles early Wednesday morning in a car crash just off the Ville Marie Expressway.

Just before 1 a.m. the woman driving the car took the eastbound Mountain St. exit but failed to make the turn.

She drove into the concrete barrier and injured herself, although she is expected to survive.

St. Antoine St. and the Mountain St. exit were closed for about an hour.

Police said the woman had not been drinking alcohol, and was not speeding.
