St. Louis, MO  (KTRS)  History has been made today as Lyda Krewson was sworn in as St. Louis’s first female mayor.

The inauguration of the longtime Alderwoman of the 28th ward was held at noon at St. Louis City Hall. Krewson will serve as St. Louis’ 46th mayor, succeeding Mayor Francis Slay, St. Louis’ longest-serving mayor.

Kansas City Mayor Sly James delivered the pre-inaugural address to a packed rotunda in City Hall. St. Louis County Executive Steve Stenger and St. Clair County Chairman Mark Kern were also in attendance.

Krewson says her main priority is reducing crime, and she plans to bolster the city’s police force, but, she says government can’t do it alone. She also pointed to the economic growth in the Grove, on Cherokee Street, Cortex in the Central West End, the Delmar Loop and and the new NGA hub in North City, all of which didn’t exist 20 years ago. Krewson says St. Louis is now the fourth most attractive city for young people to live, and she hopes to lead the city in continuing along that track.

Comptroller Darlene Green was also sworn in Tuesday afternoon.
