The Chicago Department of Transportation (CDOT) announced that the pedestrian bridge at North Avenue over N. Lake Shore Drive will be closed to all users (pedestrians and bicyclists) for a rehabilitation project starting April 11 and remain closed until June 30.  Pedestrians and bicycle riders should use the underpass at LaSalle Street, about a block south of the bridge. 

Lake Shore Drive, starting April 18, will be reduced to two traffic lanes weeknights, in only one direction at a time between the hours of 9:00pm and 5:00 am as work progresses.   The work will be done during the overnight hours so as to minimize the traffic impact, with nightly lane closures on Sunday through Thursday nights (no closures Friday and Saturday nights).

The work involves removal and replacement of the bridge deck and the girders.  The arched top truss will remain in place.  The bridge was originally built in 1940 and the last major work was done in 1991. The total length is 268 ft.(including the access ramps and stairs at both ends). The span crossing Lake Shore Drive is 187 ft. long. The bridge width is 12’-9”.

                -- Stage 1:  work will take place in the center of the bridge; both inside lanes of traffic will be closed on North and South Bounds (total four lanes closed).

                -- Stage 2: work on the west end of the bridge; both outside SB LSD lanes will be closed to traffic.

                -- Stage 3: work will take place on the east end of the bridge; both NB LSD outside lanes be closed to traffic; in addition, the entrance ramp from La Salle Drive onto Lake Shore Drive will be closed with traffic detoured via Clark to Fullerton.
