Do you believe new road infrastructure projects significantly improve your community's daily commute?

Olathe is set to open a new roundabout at the intersection of 119th Street and Northgate Street on October 28, 2026. This intersection has been closed since March 2026 as part of a major local infrastructure project.

Why it matters

The extension is designed to create a continuous route between K-7 and I-35, aiming to facilitate smoother east-west travel. City officials also expect the improved connectivity to encourage further commercial development in the area.

The total cost for the 119th Street Extension Project is $55.7 million, covering a 1-mile gap between Northgate Street and Woodland Road. The project scope includes a four-lane divided roadway and the construction of an 800-foot bridge.

The details

The project serves as a key component of the 2025-2029 Capital Improvement Plan, which includes adding turn lanes at Iowa Street, Lone Elm Road, and Woodland Road. Work on the 800-foot four-lane bridge is currently underway to bridge the remaining infrastructure gap.

March 2026: The intersection closed for construction.
October 28, 2026: The roundabout opens to traffic.
November 2026: The 800-foot bridge is expected to open.
Spring 2027: Art is scheduled to be installed in the roundabout.

Market Landscape

This construction project follows the directives set forth in the city's adopted 2025-2029 Capital Improvement Plan. The expansion prioritizes critical infrastructure development to align with projected commercial growth and regional traffic patterns.

Commuters can expect the intersection of 119th Street and Northgate Street to reopen for travel starting October 28, 2026. Residents should anticipate continued construction activity in the area until the bridge project is completed in November.

The takeaway

The opening of this roundabout marks a significant milestone in the 1-mile extension effort to improve regional connectivity. Local travelers should remain alert for ongoing construction as the project nears its final completion date in late 2026.

What happens next

The city will open the 800-foot bridge on 119th Street by the end of November 2026, followed by the installation of public art in the roundabout during the spring of 2027.
