Cascade, Weekly: I-43 Construction Expands, Highway 28 Corridor Update
Road construction is the dominant story for Cascade residents this week, as major state highway projects move from planning into active work zones across Sheboygan County.
I-43 Reconstruction Now Underway
Work officially began March 2 on a 10-mile stretch of Interstate 43 running from Wilson/Lima Road to WIS 42 in Sheboygan County. The project includes resurfacing deteriorated pavement, improving bridges, updating guardrails and replacing aging sign structures.
According to the Wisconsin Department of Transportation, tree clearing and right-of-way fencing started earlier this month with minimal traffic disruption. However, long-term lane closures began in mid-March and will continue into July.
For Cascade residents who commute north toward Sheboygan or south toward Plymouth and beyond, that means slower travel and potential backups, especially during peak hours. Officials note that intermittent lane closures will continue through November, with the most disruptive phase expected later this summer at the I-43 and Highway 23 interchange.
Ramp Closures Coming Later This Year
While the largest ramp closures are scheduled for July and August, drivers should be aware that several ramps — including County V, WIS 28 and WIS 42 — are expected to have short-term closures lasting up to two days at various points between March and November.
State transportation officials encourage drivers to check 511 Wisconsin before traveling and to allow extra time when passing through work zones.
WIS 28 Corridor Remains a Key Focus for Cascade
WIS 28, which runs directly through the Village of Cascade, continues to be part of longer-term state highway improvement planning in Sheboygan County. The corridor connects Cascade to Waldo, Plymouth and Interstate 43, making it one of the village’s most critical transportation routes.
Past updates from WisDOT have emphasized maintaining access to homes and businesses during construction activity along WIS 28. While no new detour announcements were issued this week specifically for Cascade, residents should expect that any ramp or interchange work tied to I-43 could indirectly affect travel patterns on 28.
What Cascade Drivers Should Expect This Week
With spring arriving and temperatures forecast to swing from mild to cooler conditions, construction crews are ramping up activity countywide. Daytime work zones and reduced speeds are likely along I-43, and motorists should watch for changing traffic patterns.
Officials continue to remind drivers to slow down in work zones and remain alert for lane shifts, especially as long-term closures are now in place.
Looking Ahead
The I-43 project is expected to run through late October or early November, weather permitting. Additional impacts at the Highway 23 interchange are anticipated mid-summer.
Residents with regular highway commutes may want to begin building in extra travel time now as construction season accelerates across Sheboygan County.
