The Colorado Dept. of Transportation has selected the team of Felsburg Holt & Ullevig (FHU) and Edward Kraemer and Sons Inc. for the U.S. 6 design-build project. It will reconstruct 6th Ave. (U.S. 6) from Knox Court to just east of I-25, replace five bridges that are either structurally deficient or functionally obsolete and improve the Federal Boulevard-U.S. 6 interchange.


“We are extremely excited to have a team selected for this critical transportation improvement project,” said Kevin Sullivan, CDOT Project Director. “This project will provide many benefits to the Denver metro area and for the state of Colorado. We will not only make our transportation system safer and more efficient, but we can also support economic and job growth.”


FHU and Edward Kraemer and Sons Inc. were selected from three design-build teams that submitted proposals. CDOT evaluated the proposals based on the project goals and criteria to manage impacts during construction, maximize the use of available funds and demonstrate a commitment to enhance the established project values of maximizing safety, quality, environmental and project communications.


CDOT’s original scope of the project included the following components:

• Replacement of five bridges: U.S. 6 over Bryant Street, U.S. 6 over the South Platte River, U.S. 6 over the Burlington Northern Santa Fe Railroad east of I-25, U.S. 6 over I-25 and Federal Boulevard over U.S. 6;

• Improvements to the I-25/U.S. 6 interchange that will improve mobility

• Partial closure of the Bryant Street interchange to help improve safety and mobility

• Completion of the diamond interchange at U.S. 6-Federal Boulevard with slip ramps to Bryant Street;

• A braided ramp providing access from Federal Boulevard to eastbound U.S. 6

• Improvements to Federal Boulevard between 5th Avenue and 7th Avenue;

• Upgrading portions of the South Platte River Trail to current standards;

• Reconstruction of U.S. 6 with collector-distributor roads and auxiliary lanes from Federal Boulevard to the BNSF Railroad Bridge;
