Major Reconstruction Of Highway 285 Begins

3 Bridges To Be Replaced As Part Of 18-Month Project

The Colorado Department of Transportation has started on a major project along U.S. Highway 285, known as Hampden Avenue, in Lakewood and southwest Denver.

The four-mile, $40.1 million design-build project will reconstruct Hampden Avenue and replace three bridges between Federal Boulevard and Kipling Street. The three bridges to be replaced were constructed before 1965 and are considered structurally deficient.

"Much of the pavement along this corridor is in poor condition and must be completely replaced in order to restore the service life of the roadway,” said CDOT Project Manager Tony Gross. “We also have three bridges in poor condition that must be replaced. By reconstructing and replacing these elements of our highway system, we will greatly improve an infrastructure that has deteriorated over the years.”

Construction will begin next week near the Hampden Avenue and Federal Boulevard interchange and move west. Hampden Avenue will be realigned to allow crews to reconstruct the median, but two lanes will remain open during the project.

"The two lanes of Hampden will stay open except for bridge demolition, girder installation and traffic realignments. We'll have some speed reductions going each way at times to get this thing built but we'll keep a close eye on that to try to reduce traffic delays,” said Gross.

In all, the project will make the following improvements:

  • Reconstruct approximately four miles of Hampden Avenue between Federal Boulevard and Kipling Parkway
  • Replace the bridges on Hampden Avenue over Wadsworth Boulevard, Pierce Street and Federal Boulevard
  • Add additional through lanes and reconstruct the Hampden Avenue/Wadsworth Boulevard intersection
  • Rehabilitate the bridge decks on Hampden Avenue over Estes Street, Bear Creek, Raleigh Street and Sheridan Boulevard
  • Widen the inside shoulder of Hampden Avenue between Wadsworth Boulevard and Sheridan Boulevard
  • Add an additional left turn lane from southbound Knox Court to eastbound Hampden Avenue
  • Construct drainage and water quality improvements to accommodate potential future widening or other construction projects

    The project is scheduled to be completed by the end of June 2011. For more information about this project, visit Highway 285 Project
