Greenfield commuters, rejoice!

All ramps in the Mitchell Interchange are now open to traffic, as Patch's media partners at Fox 6 report.

The last two ramps reopened Tuesday morning: the ramp connecting College Avenue with northbound I-94 (toward downtown Milwaukee) and the ramp from Layton Avenue to northbound I-94.

Fox 6 reports that some cleanup work and striping is still needed in the Mitchell Interchange, but delays should be minimal. Work to reconstruct the interchange started back in March of 2009.

Construction will continue on the I-94 north-south corridor between Milwaukee and the Illinois border through 2017. In Oak Creek, that includes a reconstruction of the Rawson Interchange next year and the Ryan Interchange in 2014.

Progress continues on the new Drexel Interchange in Oak Creek. Three of the four ramps have been constructed, all storm sewer work is done and grading is about 90 percent complete, City Engineer Mike Simmons wrote in an update Oct. 2.

The Drexel Interchange is expected to open in mid- to late-November.
