Bluemound Road construction continues through Aug. 28 in Brookfield area

Waukesha County began construction June 8 on County Highway JJ, also known as Bluemound Road, and the project is scheduled to continue through Aug. 28, 2026. The work covers the segment between County Highway J, or Pewaukee Road, and U.S. 18.

The project includes the Town of Brookfield, along with the City of Pewaukee and the City of Waukesha. That puts active road work on a corridor used by residents, commuters and local businesses for travel and access in the Brookfield area and nearby communities.

What the project covers

Waukesha County’s project description identifies the road as CTH JJ/Bluemound Road and sets the limits at CTH J/Pewaukee Road on one end and U.S. 18 on the other. The published construction window runs from June 8 through Aug. 28, 2026.

The county’s description specifically names the Town of Brookfield. The Town of Brookfield is a separate jurisdiction from the City of Brookfield, and the available information does not establish that this project affects the City of Brookfield proper. The work should not be described as a City of Brookfield project.

What travelers should expect

The approved project information identifies construction-related delays, access changes and work-zone conditions as practical concerns for people using the major east-west corridor. It does not, however, provide a specific daily lane closure, detour route or closure schedule.

The available summary also does not identify the contractor, project cost or exact phases of work. Those details cannot be inferred from the overall construction dates. Travelers and people relying on access to nearby businesses should check current county traffic information before using the corridor, rather than assume that a particular closure or detour is in effect.

Where to find updates

Waukesha County Public Works maintains a road-project and closure guide covering active improvements, short-term closures and emergency closures. The guide also includes 2026 paving-location information for CTH JJ/Bluemound Road.

That guide is the county’s identified source for current project and closure information. Conditions may change as work proceeds, so the guide is the appropriate place to check for updates affecting travel, access and work-zone conditions.

Completion target

Aug. 28, 2026, is the project’s published completion target, not a guaranteed completion date. The available source packet does not report that construction is complete and does not include a later county update changing the schedule. Unless the county issues a new notice, the project remains scheduled to continue through that date.
