I-25 widening between Lincoln Avenue and County Line Road in Douglas County substantially complete

March 11, 2016 - Denver Metro/CDOT Region 1 - Representatives gathered this morning to recognize the substantial completion of the Interstate 25 widening project between Lincoln Avenue and County Line Road.

LONE TREE – Representatives from CDOT, Douglas County, the City of Lone Tree, the Denver Regional Council of Governments, the Federal Highway Administration and prime contractor Interstate Highway Construction gathered this morning to recognize the substantial completion of the Interstate 25 widening project between Lincoln Avenue and County Line Road.

Both directions of I-25 are now in their final configuration, adding an additional lane in each direction in northern Douglas County. This is the last section of I-25 to be widened between the Broadway/Santa Fe Drive area in Denver and south Castle Rock. Southbound I-25 has been in final configuration since Saturday.

Motorists are already experiencing significant travel time improvement with a fourth through lane. Peak hour travel speeds on northbound I-25 jumped 270-percent after the fourth lane opened in November. Considering 120,000 vehicles per day travel the corridor, the total daily user cost benefit is projected to exceed the $32 million project cost in under two years. 

The project exemplifies the importance of multi-agency and private partnering. “With the help of funding from DRCOG, Douglas County, the Denver South Transportation Management Association, the Southeast Public Improvement Metropolitan District, the City of Lone Tree and Park Meadows, we were finally able to deliver on the plans to widen this section of I-25, which were made years ago,” said Shailen Bhatt, CDOT Executive Director.

“Our investment of public monies in a dependable transportation network not only puts Douglas County at a competitive advantage for our share of limited state and federal dollars, it also creates a magnet for business and jobs and improves the quality of life for those we all serve,” said Roger Partridge, Douglas County Commissioner.

By the numbers:

  • 120,000 vehicles per day drive through the project
  • 70 million vehicles passed through the work zone during construction
  • 38,210 tons of recycled concrete and 86,120 tons of recycled asphalt from the old highway were placed back into the roadway
  • 270-percent increase in peak hour travel speed since four lanes opened on northbound I-25
