Interstate 69 is about to get a little wider northeast of Indianapolis.

The Indiana Department of Transportation has selected Columbus-based Milestone Contractors LP and Indianapolis-based United Consulting Engineers and Architects for an $85 million project to widen the busy interstate through much of Hamilton County.

INDOT officials presented the plan Thursday night to residents at Noblesville City Hall. The project will add another travel lane in both directions along I-69 for 15 miles, from the 116th Street exit in Fishers to State Road 38 near Pendleton in Madison County.

Plans also include adding a southbound lane between 116th Street and the future 106th Street interchange, reconfiguring exit 210 at Campus Parkway into a diverging-diamond design and widening the Campus Parkway bridge over I-69.

The project is part of the Major Moves 2020 initiative, which is Gov. Mike Pence’s plan to spend $400 million to rehabilitate existing highways.

Construction is expected to start in the spring and continue through fall 2017.

It’s the third road project scheduled for the area near I-69 in Fishers with overlapping construction timelines. INDOT introduced designs for the $34 million new interchange at 106th Street and I-69 in September. The project would create a two-lane, oval-shaped roundabout on 106th Street over the highway with ramps to and from both directions.

Construction on that project is expected to start in April 2016 and be finished in June 2017.

During that time, 106th Street traffic would be detoured to Hague Road, 96th Street and Lantern Road. All lanes on I-69 would remain open during the day, but there would be nighttime closures for bridge construction and other work.

INDOT and local officials say the new exit is needed to reduce traffic congestion and improve safety along I-69 between 96th and 116th streets.

Fishers is also expected to start construction by summer 2016 on a $6 million project to reduce congestion to the east of I-69 along 116th Street.

The project includes adding a new eastbound lane on 116th Street from I-69 to Cumberland Road and removing the traffic signal at USA Parkway. A new traffic signal would be installed at 116th Street and Exit Five Parkway with double left turn lanes from eastbound 116th Street onto Exit Five Parkway and at Oak Drive onto 116th Street westbound.

Oak Drive also would be widened and extended south to intersect with USA Parkway.

Construction is expected to be completed by summer 2017.

INDOT officials said Thursday night that lane shifts would occur during construction of the widening project, but two travel lanes in each direction would be open. Lane closures would only be permitted during non-peak times on nights and weekends.
