INDOT to rebuild north-side 465; Carmel officials outline phased work and local impacts

At the Homeplace Advisory Board’s February 2025 meeting, Tony Green, South Central District counselor, and Jeremy Cashman of Carmel’s city engineering team described a multi-year Interstate 465 reconstruction and related local projects that will affect travel and nearby neighborhoods.

Green said INDOT plans to redesign stretches of north-side I‑465 to increase capacity and safety, and that work is expected to start in “probably the next 3, 4 months.” He told the board the project will include new lanes on the north side and specific changes at the 106th Street exit: “The difference is gonna be the Hundred And Sixth Street. What they're looking at is carving out the individuals who wanna go to 96 And A Hundred And Sixth Street. There'll be a separate lane, and those individuals will have to go to a stoplight.”

The stoplight at the 106th exit was described as a change from the current loop exit; city staff said INDOT’s design team discussed alternatives, including roundabouts or other transition treatments, but public-safety and traffic-volume concerns are driving the initial design.

Jeremy Cashman said INDOT is in a middle-of-the-road design stage and contractors are pricing work; Carmel staff are meeting with INDOT every two weeks to digest details and coordinate phasing. “There will probably be some limitations at the time, but most of what they went through with us today was there are different ways they're detouring traffic to maintain,” Cashman said, adding that INDOT is working to preserve interstate connectivity during construction.

Board and staff members also outlined progress on separate but overlapping local projects. City engineers described a three-phase program for College Boulevard between 96th Street and 106th Street, including two roundabouts:

- Phase 1: work between north of 96th up to about 101st/90th Street, with construction dates noted in city materials as roughly March 17 to July 3; the 96th/College roundabout was included in this phase. - Phase 2: the 102nd Street roundabout connecting into Parkwood, beginning after phase 1. - Phase 3: converting the corridor up through 106th into a rebuilt College Boulevard with widened lanes, curbs and multiuse paths; staff estimated about 12 months for all three phases.

Staff warned the combination of College Boulevard construction and INDOT’s 465/US‑31 work could cause localized congestion, especially during the early stages of the interstate project. Jack Reinhart, a board member, said engineers are coordinating with the police department to monitor cut-through traffic and asked residents to report specific neighborhood traffic concerns to the Carmel Police Department.

Residents asked staff about immediate local impacts. Evelyn Sellers, who lives at the corner of 100th and Second and College, asked when contractors will restore her yard; Cashman replied that utility cutovers are typically scheduled in advance and that city staff would have someone meet with her to discuss the schedule and points of contact. Ron Woods asked whether homes on Cornell near 101st — a small eight-house area that runs toward I‑465 — could be taken for the expansion; Cashman said, “No. You should be in good shape.”

Officials emphasized that more-detailed detour and schedule information will be publicized as INDOT and the city finalize contractor schedules. Cashman and Green said the city would share contacts for the College Boulevard contractor and for project updates.

Residents should expect sustained construction activity: Green told the board he was told the INDOT program “is gonna take about 3 years to complete.”
