We have helped our clients implement hundreds of projects, from large national and regional projects and programs to small, locally important initiatives. Here are some highlights of projects we are currently working on:

I-70 Mountain Corridor, Floyd Hill

Peak, in partnership with Atkins Global, is leading the Environmental Assessment, conducting technical analyses, and supporting a comprehensive Context Sensitive Solutions stakeholder process for this project. The Project will add a third lane on I-70 through the mountains in Jefferson and Clear Creek counties and advance transportation improvements on a critical bottleneck of the I-70 Mountain Corridor. The Project builds on recent transportation investments consistent with the Programmatic EIS, which Peak staff also helped managed for CDOT. 

Front Range Passenger Rail Implementation, Colorado

Peak is part of the HNTB team and leading the planning for passenger rail along Colorado's Front Range, connecting major population centers of Pueblo, Colorado Springs, Denver, and Fort Collins. We are building on prior project development alternatives analysis, stakeholder engagement, environmental data collection, and agency coordination completed in 2020 for the Southwest Chief and Front Range Passenger Rail Commission, now the Front Range Passenger Rail District. 

Advancing Lincoln Avenue

Peak is supporting the City of Lone Tree, Douglas County, and Wilson Engineering on the pre-NEPA and NEPA project development to develop and implement a multimodal vision for Lincoln Avenue between Oswego Street and Park Meadows Drive, including the interchange with Interstate 25, the Havana Avenue intersection, RTD light rail stations, numerous trails and bicycle facilities, and a planned transit mobility hub.


Lincoln Avenue is a vital regional arterial in Douglas County. This stretch of Lincoln Avenue is the gateway to Lone Tree’s City Center and the heart of significant existing and planned developments; health facilities; shopping; residential areas; business centers; and regional road, transit, and trail systems. Providing safe and reliable travel options for those who work in, live in, and commute through the area is vital to the community’s success.
