|The junction of Michigan Avenue, Oak Street, and Lake Shore Drive before the tunnel was constructed. Circa 1920s.|
The $5 million tunnel at Oak Street was designed to move northbound traffic on Michigan Avenue onto a ramp providing access to northbound Lake Shore Drive, which opened for its first rush hour. The tunnel eliminates a bottleneck that has plagued Lake Shore Drive at Oak Street for years.
The tunnel extends under new northbound and southbound strips of Lake Shore Drive. The 27-foot wide underground roadway will handle only northbound traffic, which has been using a detour over what will become the new southbound segment of the drive.
