DANBURY — When drivers on Interstate 84 cross the border into Connecticut, a billboard thanking frontline workers will greet them.

The 900-square-foot billboard installed this week honors medical, fire, EMT, police and National Guard “heroes” who have faced health risks while working throughout the coronavirus pandemic.

Danbury area businessman George Mulvaney and Janette Blackstock, of Mulvaney Mechanical, worked with Mayor Mark Boughton and city department leaders to create the 15-foot high by 60-foot wide sign.

“We are very grateful to George and everyone at Mulvaney Mechanical for this extraordinary salute to our first responders and medical personnel who work hard every day to ensure the general health, safety, and welfare of our residents,” Mayor Mark Boughton said

The message is on the eastbound side of I-84 near the New York state line and includes pictures of local police, fire and health care workers, captured by local photographer J.C. Martin. In the center is a panoramic photo of frontline workers and a CT National Guard unit with Danbury Fire's 90-foot aerial truck flying an American Flag.

The sign reads “proudly saluting our hometown heroes.”
