FORT WAYNE, Ind. (WANE)– The Martin Luther King Jr. Bridge lighting for Congenital Diaphragmatic Hernia Awareness day is canceled for Tuesday night.

The bridge was supposed to shine in yellow, pink, and blue in support of Congenital Diaphragmatic Hernia Awareness day, which takes place on April 19th. The cancelation is due to lighting improvements on the bridge, according to the City of Fort Wayne website. Construction is scheduled to be completed in late April.

According to Johns Hopkins Children’s Hospital, CDH is when the diaphragm doesn’t fully form, which causes holes and allows abdominal organs to move to the chest preventing lung growth.

CDH International says the birth defect occurs in 1 in 25-hundred births, but the cause is unknown.
