A concert series hosted on a historic Washington County bridge continues tomorrow. Sean Costanza and Cedar County Cobras are set to perform on the river crossing built by King Iron Bridge Company in 1887. The concert, part of Friends of Bunker Bridge’s Almost Acoustic Tuesday series, begins at 6:30 p.m. Proceeds from the concerts go toward the restoration of the bridge, located between Kalona and Richmond, that was damaged when it was set on fire in 2013.
