Signia By Hilton and Indiana Convention Center Expansion

Construction has begun on the 143,500-square-foot center expansion, including a 50,000-sq.-ft. ballroom, that will connect to a new 800-room Signia by Hilton, creating an unrivaled convention package.

The new property will stand 38 stories tall and will include a top-level bar with skyline views. This project is anticipated to open fall 2026.

Indy already touts the most hotels and hotel rooms connected by enclosed skywalks into a center in the U.S., and this expansion will boost those numbers to 12 properties and 5,200+ hotel rooms all under one roof.
