Will the planned I-75 construction lead to major traffic delays in your area this weekend?
Interstate 75 in Cincinnati will close in both directions between September 25 and September 28, 2026, to allow for bridge beam installation. This work is a core component of the Linn Street Bridge Reconstruction project.
Why it matters
The closure is required to safely facilitate the installation of bridge beams over the interstate. This critical phase of the construction project will significantly impact regional traffic flow for the duration of the weekend.
Great Lakes Construction holds a $46.7 million contract for the Linn Street project. The work includes plans to reconfigure the bridge to accommodate two 10-foot driving lanes.

This firm is the primary contractor responsible for the execution of the Linn Street Bridge Reconstruction project.
The details
Crews will begin implementing lane closures on September 25, 2026, leading up to the full interstate shutdown at 11 p.m. Motorists traveling through the area are advised to use signed detours involving Interstate 71 and SR-562 to navigate around the construction zone.
Timeline
September 25, 2026, 9 p.m.: Entrance ramps begin closing.
September 25, 2026, 11 p.m.: Full interstate closure begins.
September 27, 2026, 8:30 p.m.: U.S. 50 to I-75 South ramp closes.
September 28, 2026, 5 a.m.: Full interstate closure ends.
January 2027: U.S. 50 ramp closure ends.
Market Landscape
This project reflects the ongoing regional commitment to upgrading aging transportation corridors and bridges. It aligns with broader industry trends focusing on large-scale infrastructure renewal to improve safety and transit capacity.
Drivers should prepare for significant delays and plan to use the I-71 and SR-562 detours throughout the closure weekend. Those who frequently use the U.S. 50 ramp to reach southbound I-75 will face an extended four-month route adjustment beginning in late September.
The takeaway
Commuters should anticipate major disruptions to their weekend travel plans in the Cincinnati area. Early preparation and familiarity with designated detour routes are essential for navigating the construction period efficiently.
What happens next
The U.S. 50 to I-75 South ramp is scheduled to remain closed until January 2027. Additionally, the Linn Street Bridge is expected to reopen in the fall of 2027, with full project completion anticipated in the spring of 2029.
