US 31 Hamilton County Reconstruction

Located on the north side of Indianapolis, US 31 underwent a $358 million transformation and upgrade including 13 miles of signalized arterial roads to a full freeway facility, sustainable design of 46 bridges, 21 roundabouts, and 11 interchanges. As a major connector between I-465 and SR 38, it was imperative to upgrade US 31 to meet federal freeway standards.

Keeping safety in mind, our team provided an innovative solution — a system of “back-to-back” roundabouts — some of the first-ever built by INDOT and one of the country’s most complex series designed to provide a seamless freeway corridor. The newly reconstructed six-lane freeway was completed two years ahead of schedule and over $100 million under budget. CHA’s final design reduced congestion, improved safety, and provided reliable, efficient commerce and regional travel.
