This unusual bridge carries La Salle Street over Carroll Avenue and old railroad line. The wide bridge transitions into two ramp leading down to ground level as it runs north, with a gap opening in the center to admit a ramp that runs up from Carroll Avenue. This ramp in the center once provided access to a tunnel that ran under the Chicago River. The La Salle Street tunnel was the second tunnel in the city and was opened in 1871, a few months before the Great Chicago Fire. People fleeing the fire actually used the tunnel to escape the fire. The tunnel was abandoned and closed off when the Blue Line subway was built, but the ramp and overpass system has remained. It is not known if the attractive decorative railings seen on this structure are an original detail.
