The new interchange at I-43 and Highland Road in Mequon is now open, providing easier access to Concordia University Wisconsin, as part of the ongoing reconstruction project that will widen the stretch of freeway from Glendale to Grafton from four to six lanes.

Up next will be the upgrading of the interchange at Pioneer Road, or Highway C,  which will result in its closure for most of 2023. That work is expected to begin in February.

The $550 million I-43 project involves expanding the freeway to three lanes in each direction along the 14 miles from Silver Spring Drive in Milwaukee County to Highway 60 in Grafton.

It also includes modernizing six interchanges and building the new one at Highland Road. A section of Port Washington Road in Glendale also will be widened.

The interchanges, bridges and pavement have been in place for more than 50 years, according to the state Department of Transportation, and are at the end of their useful life.

That stretch of freeway is among the busiest in Wisconsin, carrying 53,300 vehicles per day south of Highway 60 and 96,700 vehicles per day north of Silver Spring Drive, according to the DOT.

Two lanes of I-43 are expected to remain open in each direction throughout construction.

Future projections show traffic growing by 2045 to 63,000 vehicles per day south of Highway 60 and 111,700 vehicles per day north of Silver Spring Drive.

The project is expected to be completed in 2025, with the “north end segment,” stretching from Highland Road to Highway 60, scheduled to be finished by mid-2024.
