Project History

The roadway to a road project
The North Meadows Extension is not just one of the largest road projects in the state. It is also one of the most complex.

Once completed, the 2-mile road will bridge over the BNSF Railway line, Plum Creek, and a Union Pacific Railroad line. It will intersect with two highways and have a total grade change of more than 20 stories.


The need for the road dates back to the mid-1980s when The Meadows development was told a second connection to U.S. Highway 85 would be needed to accommodate traffic volumes associated with new residents moving to The Meadows. An initial master plan, developed in 2003, showed a need not only for a connection to U.S. 85, but also to Interstate 25.

Public meetings were held in 2003 and 2004. At the time, the Castle Pines Village community came out in numbers to reject the idea of another connection to I-25, because of the impacts it would create to the southern area of Castle Pines Village. Support from CDOT and Douglas County was also lukewarm at the time, so more public input was necessary.

That public input led to the 2005 approval of a bond issue to help construction three new major transportation projects. Called the Transportation Action Plan, or TAP for short. Two of the projects are now park of Plum Creek Parkway. The third project is the North Meadows Extension.

History of the North Meadows Extension

April 2005

More than 75 percent of Castle Rock voters approved a $30 million Transportation Action Plan bond issue to help build three roadway projects in Town, including the North Meadows Extension.

February 2006

To alleviate congestion, it is decided a new I-25 interchange is needed. Later that year, the new North Meadows Extension interchange became part of the Denver Regional Council of Government's Fiscally Constrained 2030 Regional Transportation Plan.

February 2007

The Town hosted an open house to gather input to begin the project's Environmental Assessment, a federally required process that describes the project's benefits and impacts on the surrounding area.

April 2008

The Town hosted an open house to evaluate where the road should travel. At first, the project team had more than 20 options to consider

December 2008

The Colorado Department of Transportation approved an option that would save up to $14 million - a signalized intersection at U.S. Highway 85, rather than an overpass. Still, this option would have meant moving 1 mile of Union Pacific Railroad line, which the railroad. indicated it would not do.

April 2009

The Town hosted an open house to discuss alignment alternatives. More than 600 people attended, and more than 230 comment cards were submitted after the event.

August 2009

Town Council hosted a public hearing about alignment alternatives. Town Council directed staff to continue talks with Union Pacific about moving the rail line, due to the potential cost savings of that option.

September 2009

Town Council met with state legislators about the rail line issue.

February 2010

Union Pacific again stated it would not move the rail line, the benefits to the railroad would not outweigh the costs. Town Council decided not to continue negotiations with the railroad.

April 2010

The Town hosted an open house to gather input on the complete draft of the Environmental Assessment. Town Council chose the Castlegate alignment, after having an original 20 options and hosting eight open houses, including three before the bond issue was passed in 2005.

Late 2010

Environmental Assessment is completed.

March 2011

The Federal Highway Administration reviewed the Environmental Assessment and signed a Finding of No Significant Impact, meaning the project would not negatively impact the area and, therefore, could move forward.

July 2011

A value engineering study generated more than 110 ideas for cost-savings on this project, following an increase in material costs. Town Council voted to move forward with 26 viable cost-reduction options. (The public saw some of these options during a September 2011 open house).

December 2011

Town Council chose design firm Tsiouvaras Simmons Holderness to lead design. Formal design began.

May 2012

Residents helped decide the project will cross over the BNSF Railway tracks northwest of Castle View High School, rather than under the tracks. Town Council chose Kraemer North America as the project's general contractor.

February 2013

The Town hosted an open house to gather input on the project's landscaping and other aesthetics. More than 100 people attended or provided comments online.

July 2013

The Town and Douglas County enter into an intergovernmental agreement in which the county contributes $10.5 million toward the project, specifically to construction regional areas of the project between U.S. 85 and I-25.

October 2013

A groundbreaking ceremony marked the official start of construction on the project.

November 2013

Town Council approved a contract, outlining certain conditions for the construction contractor and establishing a maximum construction budget. Council also approved the ordering of certain materials for the bridge over the BNSF Railway line, as allowed by CDOT.

August 2014

Town Council approves contracts that allow the Town to work on all three phases of the project.

February 2016

Town Council and Douglas County agree to another IGA to widen the portion of the project between I-25 and U.S. 85 to four lanes. 

March 2015

Town Council votes unanimously on a name for the new roadway. The portion between I-25 and U.S. 85 will become Castle Rock Parkway. The rest will become North Meadows Drive, as it is a continuation of the existing North Meadows Drive near Castle View High School.

August 2016

Town hosts a sneak peek event. 

Sept. 1, 2016

Road opens to the public!
