County Line Road (I-25 east side to Inverness)

Project Description

This $14 Million project involves advancing improvements located on both the west side and east side of I-25.  This multi-year project focused initially on completing the improvements on the west side of I-25, (approximately $5.5 Million), which occurred over three construction seasons (done to minimize impacts to the adjacent businesses).

The final west side construction phase (widening and reconstructing the southbound I-25 off-ramp) was substantially completed by August 1, 2019.   West side funding partners included CDOT, Centennial, Lone Tree, Park Meadows Metro District, SPIMD and Douglas County. In July 2019, the County awarded to professional service contracts to advance the proposed improvements located on the east side of I-25, which include a detailed subsurface utility engineering and final design.

The proposed east side improvements are estimated to cost $8.5 Million and include fully reconstructing the County Line Road / Inverness Parkway / Inverness Drive West closely space paired intersections that currently operate at a poor level of service.  Improvements combine two T-intersections into a single four-legged intersection. Funding partners for the east side improvements include $1 Million from the Southeast Partnership Improvement Metropolitan District (SPIMD), $1 Million from Arapahoe County and $1 Million of in-kind contributions from the Inverness Metro Improvement District for significant ROW dedication and landscaping, (which isn’t included in the $8.5 Million project cost estimate). Douglas County’s contribution to the improvements located on the east side of I-25 is estimated to be $6 Million.  Utility relocation is anticipated to occur in 2020 and construction to occur in 2021.
