Motorists traveling through one of Fishers’ busiest west-side intersections should prepare for construction later this spring as the city moves forward with roadway improvements at 116th Street and Allisonville Road.

City officials say construction on the project is expected to begin on or after March 30 and continue through October 2026. The work is aimed at improving traffic flow and safety at the heavily traveled crossing, which serves as a key north-south gateway into Fishers from Indianapolis and Carmel.

Originally, the project called for the construction of a roundabout. However, after updated traffic studies and additional analysis, the city decided to move in a different direction. Instead of a roundabout, crews will realign the eastbound approach of 116th Street and adjust pavement markings at the intersection to better accommodate traffic, particularly vehicles turning north onto Allisonville Road.

City officials say the revised design should help keep traffic moving more efficiently without requiring the larger reconstruction that a roundabout would have required.

The intersection sits along the Allisonville Road corridor, an area the city has identified for long-term improvements as part of broader redevelopment and mobility efforts on the west side of Fishers. The corridor includes nearby investments such as the new roundabout at 96th Street and Allisonville Road, upgrades to signal systems, beautification efforts, and new commercial development.

During construction, drivers can expect lane shifts, restrictions, and slower travel through the intersection, particularly during peak commuting hours. However, both the intersection and nearby businesses will remain open throughout the project, according to city officials.

As with most roadway projects in Indiana, work schedules may shift depending on weather conditions.

Fishers officials say the improvements should help the intersection accommodate projected traffic volumes for years to come, providing a safer and more efficient route for drivers traveling through the area.

The intersection of 116th Street and Allisonville Road was built in the late 1990s and has experienced steadily increasing traffic as Fishers has grown into one of the fastest-growing communities in Indiana, with a population approaching 107,000 residents.

When completed in the fall of 2026, city leaders say the project will represent another step in modernizing key transportation corridors across Fishers while supporting continued growth on the city’s west side.
