Marquette County CTH E roadwork starts July 13: detours + resident access rules

Oxford-area drivers should plan ahead starting Monday, July 13, 2026. Marquette County says crews will begin pavement replacement on County Trunk Highway E (CTH E) between CTH J and CTH B, with traffic control using flagging operations.

The county’s guidance includes two key impacts: resident-only access during flagging and a signed detour for other drivers. It also notes that access to United Co-op will be maintained from CTH J (with minor delays expected).

What’s happening on CTH E

Marquette County’s notice focuses on pavement replacement along CTH E from CTH J to CTH B. During the project, the county will use flagging to manage traffic while crews work in sections of the highway.

Resident-only access during flagging: what to expect

When flagging is in effect, the county says CTH E will be open to resident traffic only. If your trip normally uses CTH E as a through route, follow the county’s traffic control plan and on-site signage so you don’t get routed into the wrong access area.

Detour route for other drivers

Marquette County says other traffic will be directed to a signed detour using CTH J and CTH B. During the flagging period, assume that detour guidance will be the default routing—then adjust based on the signs you see when you reach the work zone.

United Co-op access: maintained from CTH J

The county also addresses United Co-op access. Marquette County says access will be maintained from CTH J, but drivers should expect minor delays at times during construction and flagging.

Work hours and the projected completion week

Marquette County lists anticipated work hours of 6 a.m. to 7 p.m., Monday–Friday. The county also says weekend work is possible, so plan for the corridor to be active outside the standard weekday schedule.

For timing, the county projects completion during the week of Sept. 7, 2026, weather dependent. That means readers should expect schedule adjustments if conditions change.

Where to check for updates

Traffic rules can change as flagging phases move, so keep an eye on Marquette County’s current and upcoming highway projects hub for the latest project updates alongside the day-to-day notice.
