Highway 100 work stretches into Greenfield

Hearing on two-mile 2018 road project set for Thursday

Jan. 14, 2014

Greenfield — A proposed Highway 100 project through Hales Corners will also have an impact on the south side of Greenfield.

Among other things, the Wisconsin Department of Transportation's two-mile project, which won't begin until 2018, would relieve congestion at the Interstate 43 ramps at Highway 100. It also seeks to improve the intersection of Highway 100 with Edgerton Avenue.

A public hearing on the $25.1 million project will be held from 5 to 8 p.m. Thursday at the Hales Corners Municipal Building, 5635 S. New Berlin Road. People can view exhibits and provide input privately.

Due to the typical long delays during heavy traffic, the I-43 ramps are rated very poorly under the system used to evaluate intersections. Also, some turning movements at Edgerton also have a failing grade.

At Edgerton Avenue, a fourth southbound travel lane would reduce lines of traffic so that they do not reach the nearby I-43 off-ramp. That should help relieve congestion at the ramp, said Vida Shaffer, DOT project manager, adding that the fourth lane also will reduce the traffic weaving.

Congestion isn't a problem at the northbound on-ramp, Shaffer said, but there still will be minor changes to increase efficiency.

Most of the work will take place in Hales Corners, from College Avenue stretching north to Layton Avenue in Greenfield.

The preferred project plan proposes reconstructing Highway 100, which would still be six lanes with a median, plus the addition of a 5-foot-wide shoulder.

The plan also calls for the two bridges over I-43 to be widened to the inside to allow the three lanes in each direction and shoulder, though the interchange area may be re-evaluated tied to future road projects.

Even though the proposed project doesn't hit the city in a major way, Greenfield Mayor Michael Neitzke said residents and business owners should know about what is being proposed.

"It's just a potentially dramatic project that will likely impact a lot of people and commerce in the southwestern part of the county, and people should know about the meeting to see what's proposed," he said.
