The Underground District has been constructing underground facilities for over 50 years and is recognized as a leader in the tunneling industry. We have completed more than 100 underground-related projects totaling more than $1 billion. Our work includes projects related to transportation, environmental facilities, power, mining, bridges and telecommunications. We incorporate state-of-the-art technology with proven construction methods to ensure excellence and ongoing success. Kiewit’s decentralized organizational structure allows us to compete both locally and nationally. Our projects range from fast-track mining jobs to a $1 billion undersea rail tunnel.
The Underground District conducts its operations primarily through Kiewit Infrastructure Co., part of the Kiewit Infrastructure Group and a subsidiary of Kiewit Corporation.
