To mitigate congestion along Interstate 25 (I-25), the Colorado Department of Transportation and Regional Transportation District initiated the $1.67 billion Transportation Expansion Project (T-REX). The first design-build project in the country designed to accommodate future growth, the T-REX was planned to avoid disrupting traffic and with an ambitious five-year design and construction schedule.
Kleinfelder’s ability to understand, accommodate, and engage in remediation for existing and sometimes undesirable site conditions helped the T-REX project achieve timely and under-budget completion.
