View CDOT’s Fall-Winter 2009 Metro Denver Projects in a larger map

CDOT and the contractors building metro Denver highway improvements plan to carry on through much of the cold weather season with projects ranging from intersection improvements and signals to heavy construction such as bridge replacement.

Twenty-seven construction projects valued at a total of $324.3 million are either already underway or will start in the next six months. They range from the $40.1 million design-build reconstruction of the Hampden Avenue freeway including new bridges over Federal Boulevard, Pierce Street and Wadsworth Boulevard, to the $150,000 installation of an experimental noise wall made of recycled tires along the Sixth Avenue Frontage Road between Coors and Alkire streets.

The details of these projects are on the map above. Clicking on the blue balloons will bring up the stats including cost, contractor, CDOT resident engineer on the project, scope of work, work hour traffic impacts and planned duration of the job.

You can drag the map around with your cursor, plus zoom in and out to see the locations on the ground.

So far, 14 companies are at work or have been awarded contracts for this work, with 11 projects still to be awarded. Two companies have two contracts each. The general contractors working on metro Denver CDOT projects over the fall-winter season are Edward Kraemer and Sons, Hamon Contractors, SEMA Construction, Zak Dirt, Castle Rock Construction, Jalisco International, American Civil Constructors, Flatiron Constructors, DKS Enterprises, Structures Inc., New Design Construction Co., ABCO Construction, Brannan Sand and Gravel and Concrete Express.

Among some of the larger projects is replacement of the Alameda bridge over Interstate 25 – an original Valley highway bridge built in 1958. This is one phase of a plan to upgrade and widen the remaining six-lane segment of I-25 in Denver to eight lanes at this persistent bottleneck.

The list also includes widening Interstate 225 to six lanes from Second Avenue to Mississippi avenues, allowing for the extension of the six-lane profile farther south and loosening up the congestion jamming around Alameda Avenue.

Another large project is widening Federal Boulevard in Denver to six full lanes in each direction, plus eight-foot sidewalks, from Alameda to Sixth Avenue.
