The US 31 Corridor project from Indianapolis to South Bend, Indiana is one of the most beneficial projects for the state. The advantages are well documented, and include both economic development benefits and travel and safety benefits.

With the completion of the US 31 corridor, businesses will see an estimated travel time savings of $454 M for Indiana trucks and another $1.2 B for automotive trips made for business purposes. An improved highway will also lead to new opportunities for business expansion and increased tourism, according to studies. These same studies show that new economic activity arising from the completion of the corridor will generate an additional 5010 jobs in the state by 2034. Overall, the economic impact of the expansion of existing businesses, the attraction of new businesses and the changes in tourist activity would produce a projected economic benefits of $1.3 B over 30 years.

Further benefits from the completion of this corridor are related to travel and safety. The reduced travel time, down to 121.9 minutes for traveling the entire 122-mile corridor, will generate $5.3 B in savings over a 30-year period. Improved safety will yield savings of another $2.6 B over 30 years. Further, vehicle operating costs will have a net projected savings of $7.3 B.
