A lighting project two years in the making on the Raccoon River Valley Trail bridge on the east edge of Adel was completed last fall. It is the highlight of the Adel Partners Chamber of Commerce work to beautify the trail as it rolls into Adel.  The bridge’s 66 color-changing LED lights are lit each night at dusk and go dark at 1 am.  Each of the 66 heads has 22 dials in it which provides over 16 million different color combinations for the bridge that was built in 1899.
