Construction has been slated to begin this fall on two new pedestrian and bicycle bridges over Lake Shore Drive at 41st and 43rd streets. They will replace an outdated bridge at 43rd Street that has no ramp for bicycle or wheelchair access.
The first bridge lift is scheduled for 8 a.m. Saturday, April 19, and they will continue every Wednesday and Saturday through June 28, according to a statement from the Chicago Department of Transportation.
Bridges carrying both north and southbound lanes of I-57 over the riverwill be replaced by December 2015.
From major spans over the Mississippi River to overpasses on traffic-choked arteries skirting Chicago, some 200 bridges throughout Illinois are in need of replacement or repair because of their outdated, insufficient design and their advanced deterioration.
Major repair work on CTA bridges is going to halt service on a stretch of the Purple Line in Evanston over the weekend.
A new study claims 71 drivers cross a structurally deficient bridge in the Chicago area every second.
