Photos: Zoo Interchange construction

Construction work is underway on what will be the new eastbound I-94 ramp to southbound I-41 of the Zoo Interchange. Project managers said about a month of construction remains before they can re-open a lane of eastbound I-94 traffic at the Zoo Interchange construction project and end the "zipper merge.'

State transportation officials are shooting for the "zipper merge" to come down in time for Thanksgiving.

About $4 million was spent after an earlier expected finish fell through.
